Azure VMware Solution Recoverability Design Considerations
Azure VMware Solution Design Series Availability Design Considerations Recoverability Design Considerations Performance Design Considerations Security Design Considerations VMware HCX Design with Azure VMware Solution Overview A global enterprise wants to migrate thousands of VMware vSphere virtual machines (VMs) to Microsoft Azure as part of their application modernization strategy. The first step is to exit their on-premises data centers and rapidly relocate their legacy application VMs to the Azure VMware Solution as a staging area for the first phase of their modernization strategy. What should the Azure VMware Solution look like? Azure VMware Solution is a VMware validated first party Azure service from Microsoft that provides private clouds containing VMware vSphere clusters built from dedicated bare-metal Azure infrastructure. It enables customers to leverage their existing investments in VMware skills and tools, allowing them to focus on developing and running their VMware-based workloads on Azure. In this post, I will introduce the typical customer workload recoverability requirements, describe the Azure VMware Solution architectural components, and describe the recoverability design considerations for Azure VMware Solution private clouds. In the next section, I will introduce the typical recoverability requirements of a customer’s workload. Customer Workload Requirements A typical customer has multiple application tiers that have specific Service Level Agreement (SLA) requirements that need to be met. These SLAs are normally named by a tiering system such as Platinum, Gold, Silver, and Bronze or Mission-Critical, Business-Critical, Production, and Test/Dev. Each SLA will have different availability, recoverability, performance, manageability, and security requirements that need to be met. For the recoverability design quality, customers will normally have an uptime percentage requirement with a recovery point objective (RPO), recovery time objective (RTO), work recovery time (WRT), maximum tolerable downtime (MTD) and a Disaster Recovery Site requirement that defines each SLA level. This is normally documented in the customer’s Business Continuity Plan (BCP). For example: SLA Name Uptime RPO RTO WRT MTD DR Site Gold 99.999% (5.26 min downtime/year) 5 min 3 min 2 min 5 min Yes Silver 99.99% (52.6 min downtime/year) 1 hour 20 min 10 min 30 min Yes Bronze 99.9% (8.76 hrs downtime/year) 4 hours 6 hours 2 hours 8 hours No Table 1 – Typical Customer SLA requirements for Recoverability The recoverability concepts introduced in Table 1 have the following definitions: Recovery Point Objective (RPO): Defines the maximum age of the restored data after a failure. Recovery Time Objective (RTO): Defines the maximum time to restore the service. Work Recovery Time (WRT): Defines how long it takes for the recovered service to be brought online and begin serving customers again. Maximum Tolerable Downtime (MTD): Sum of the RTO and WRT, which is the total time required to recover from a disaster and start serving the business again from the Disaster Recovery Site. This value needs to fit within the downtime value of the SLA for each year. Figure 1 – Recoverability Concepts A typical legacy business-critical application will have the following application architecture: Load Balancer layer: Uses load balancers to distribute traffic across multiple web servers in the web layer to improve application availability. Web layer: Uses web servers to process client requests made via the secure Hypertext Transfer Protocol (HTTPS). Receives traffic from the load balancer layer and forwards to the application layer. Application layer: Uses application servers to run software that delivers a business application through a communication protocol. Receives traffic from the web layer and uses the database layer to access stored data. Database layer: Uses a relational database management service (RDMS) cluster to store data and provide database services to the application layer. Depending upon the recoverability requirements for each service, the disaster recovery protection mechanisms could be a mix of manual runbooks and disaster recovery automation solutions with replication and clustering mechanisms connected to many different regions to meet the customer SLAs. Figure 2 – Typical Legacy Business-Critical Application Architecture In the next section, I will introduce the architectural components of the Azure VMware Solution. Architectural Components The diagram below describes the architectural components of the Azure VMware Solution. Figure 3 – Azure VMware Solution Architectural Components Each Azure VMware Solution architectural component has the following function: Azure Subscription: Used to provide controlled access, budget, and quota management for the Azure VMware Solution. Azure Region: Physical locations around the world where we group data centers into Availability Zones (AZs) and then group AZs into regions. Azure Resource Group: Container used to place Azure services and resources into logical groups. Azure VMware Solution Private Cloud: Uses VMware software, including vCenter Server, NSX software-defined networking, vSAN software-defined storage, and Azure bare-metal ESXi hosts to provide compute, networking, and storage resources. Azure NetApp Files, Azure Elastic SAN, and Pure Cloud Block Store are also supported. Azure VMware Solution Resource Cluster: Uses VMware software, including vSAN software-defined storage, and Azure bare-metal ESXi hosts to provide compute, networking, and storage resources for customer workloads by scaling out the Azure VMware Solution private cloud. Azure NetApp Files, Azure Elastic SAN, and Pure Cloud Block Store are also supported. VMware HCX: Provides mobility, migration, and network extension services. VMware Site Recovery: Provides Disaster Recovery automation and storage replication services with VMware vSphere Replication. Third party Disaster Recovery solutions Zerto Disaster Recovery and JetStream Software Disaster Recovery are also supported. Dedicated Microsoft Enterprise Edge (D-MSEE): Router that provides connectivity between Azure cloud and the Azure VMware Solution private cloud instance. Azure Virtual Network (VNet): Private network used to connect Azure services and resources together. Azure Route Server: Enables network appliances to exchange dynamic route information with Azure networks. Azure Virtual Network Gateway: Cross premises gateway for connecting Azure services and resources to other private networks using IPSec VPN, ExpressRoute, and VNet to VNet. Azure ExpressRoute: Provides high-speed private connections between Azure data centers and on-premises or colocation infrastructure. Azure Virtual WAN (vWAN): Aggregates networking, security, and routing functions together into a single unified Wide Area Network (WAN). In the next section, I will describe the recoverability design considerations for the Azure VMware Solution. Recoverability Design Considerations The architectural design process takes the business problem to be solved and the business goals to be achieved and distills these into customer requirements, design constraints and assumptions. Design constraints can be characterized by the following three categories: Laws of the Land – data and application sovereignty, governance, regulatory, compliance, etc. Laws of Physics – data and machine gravity, network latency, etc. Laws of Economics – owning versus renting, total cost of ownership (TCO), return on investment (ROI), capital expenditure, operational expenditure, earnings before interest, taxes, depreciation, and amortization (EBITDA), etc. Each design consideration will be a trade-off between the availability, recoverability, performance, manageability, and security design qualities. The desired result is to deliver business value with the minimum of risk by working backwards from the customer problem. Design Consideration 1 – Azure Region: Azure VMware Solution is available in 30 Azure Regions around the world (US Government has 2 additional Azure Regions). Select the relevant Azure Regions that meet your geographic requirements. These locations will typically be driven by your design constraints and the required distance the Disaster Recovery Site needs to be from the Primary Site. The Primary Site can be located on-premises, in a co-location or in the public cloud. Figure 4 – Azure VMware Solution Region for Disaster Recovery Design Consideration 2 – Deployment topology: Select the Azure VMware Solution Disaster Recovery Pod topology that best matches the uptime and geographic requirements of your SLAs. For very large deployments, it may make sense to have separate Disaster Recovery Pods (private clouds) dedicated to each SLA for cost efficiency. The management and control plane cluster (Cluster-1) can be shared with customer workload VMs or be a dedicated cluster for management and control, including customer enterprise services, such as Active Directory, DNS, & DHCP. Additional resource clusters can be added to support customer workload demand. This also includes the option of using separate clusters for each customer SLA. The best practice for Disaster Recovery design is to follow a pod architecture where each protected site has a matching private cloud in the Disaster Recovery Azure Region. Complex mesh topologies should be avoided for operational simplicity. The required workload Service Level Agreement values must be mapped to the appropriate Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO) and use a naming convention that is easy to understand. For example, Gold, Silver and Bronze or Tier-1, Tier-2 and Tier-3. Each pod should be designated with an SLA capability for operational simplicity. On a smaller scale, the pod concept could be per cluster instead of per private cloud. The Disaster Recovery pods are provisioned to support the necessary replicated storage capacity during steady state. When a disaster is declared, the necessary compute resources will be added to the private cloud. This can be configured automatically using this Auto-Scale function with Azure Automation Accounts and PowerShell Runbooks. Figure 5 – Azure VMware Solution DR Shared Services Figure 6 – Azure VMware Solution Dedicated DR Pods Design Consideration 3 – Disaster Recovery Solution: The Azure VMware Solution supports the following first-party and third-party Disaster Recovery solutions. Depending upon your recoverability and cost efficiency requirements, the best solution can be selected from Table 2 below. For cost efficiency, a best effort RPO and RTO can be met using backup replication of daily snapshots to the Disaster Recovery Site or using the Disaster Recovery replication feature of VMware HCX (Solution 4). If these solutions are not viable, you can also consider application, database or message bus clustering as an option. Solution RPO RTO DR Automation 1. VMware Site Recovery 5min – 24hr Minutes Yes, with Protection Groups & Recovery Plans 2. Zerto DR Seconds Minutes Yes, with Virtual Protection Groups (VPGs) 3. JetStream Software DR Seconds Minutes Yes, with Protection Domains, Runbooks & Runbook Groups 4. VMware HCX 5min – 24hr Hours No, manual process only Table 2 – Disaster Recovery Vendor Products Note: Azure Site Recovery can be used to protect Azure VMware Solution but is not listed here since we are describing how to use Azure VMware Solution to protect on-premises VMware vSphere solutions. Solution 1 – VMware Site Recovery supports Disaster Recovery automation with an RPO of 5 minutes to 24 hours with VMware SRM Virtual Appliance, VMware vSphere Replication and VMware vSAN. Currently, using VMware Site Recovery with Azure NetApp Files is not supported. When designing a solution with VMware Site Recovery, these Azure VMware Solution limits should be considered. Figure 7 – Azure VMware Solution with VMware Site Recovery Manager Solution 2 – Zerto Disaster Recovery supports Disaster Recovery automation with an RPO of seconds using continuous replication with the Zerto Virtual Manager (ZVM), Zerto Virtual Replication Appliance (ZVRA) and VMware vSAN. When designing a solution with Zerto Disaster Recovery, this Zerto Architecture Guide should be considered. Figure 8 – Azure VMware Solution with Zerto Disaster Recovery Solution 3 – JetStream Software Disaster Recovery supports Disaster Recovery automation with an RPO of seconds using continuous replication with the JetStream Manager Virtual Appliance (MSA), JetStream DR Virtual Appliance (DRVA) and VMware vSAN. When designing a solution with JetStream Software Disaster Recovery, these JetStream Software resources should be considered. Figure 9 – Azure VMware Solution with JetStream Software Disaster Recovery Solution 4 – VMware HCX Disaster Recovery supports manual Disaster Recovery with an RPO of 5 minutes to 24 hours with VMware HCX Manager, VMware vSphere Replication and VMware vSAN. When designing a solution with VMware HCX, these Azure VMware Solution limits should be considered. Figure 10 – Azure VMware Solution with VMware HCX Disaster Recovery Design Consideration 5 – SKU type: Three SKU types can be selected for provisioning an Azure VMware Solution private cloud. The smaller AV36 SKU can be used at the Disaster Recovery Site to build a pilot light cluster with the minimum storage resources for cost efficiency while the Primary Site can use the larger and more expensive AV36P and AV52 SKUs. The AV36 SKU is widely available in most Azure regions and the AV36P and AV52 SKUs are limited to certain Azure regions. Azure VMware Solution does not support mixing different SKU types within a private cloud (AV64 SKU is the exception). You can check Azure VMware Solution SKU availability by Azure Region here. The AV64 SKU is currently only available for mixed SKU deployments in certain regions. Figure 11 – AV64 Mixed SKU Topology Design Consideration 6 – Runbook Application Groups: After the application dependency assessment is complete, this data will be used to create the runbook application groups to ensure that the application SLAs are met during a disaster event. If the application dependency assessment is incomplete, the runbook application groups can be initially designed using the process knowledge from your application architecture team and IT operations. The idea is to ensure each application is captured in a runbook that allows the application to be recovered completely and consistently using the runbook architecture and order of operations. Figure 12 – VMware Site Recovery Application Recovery Plans Design Consideration 7– Storage Policies: Table 3 lists the pre-defined VM Storage Policies available for use with VMware vSAN. The appropriate redundant array of independent disks (RAID) and failures to tolerate (FTT) settings per policy need to be considered to match the customer workload SLAs. Each policy has a trade-off between availability, performance, capacity, and cost that needs to be considered. To comply with the Azure VMware Solution SLA, you are responsible for using an FTT=2 storage policy when the cluster has 6 or more nodes in a standard cluster. You must also retain a minimum slack space of 25% for backend vSAN operations. Deployment Type Policy Name RAID Failures to Tolerate (FTT) Site Standard RAID-1 FTT-1 1 1 N/A Standard RAID-1 FTT-2 1 2 N/A Standard RAID-1 FTT-3 1 3 N/A Standard RAID-5 FTT-1 5 1 N/A Standard RAID-6 FTT-2 6 2 N/A Standard VMware Horizon 1 1 N/A Table 3 – VMware vSAN Storage Policies Design Consideration 8 – Network Connectivity: Azure VMware Solution private clouds can be connected using IPSec VPN and Azure ExpressRoute circuits, including a variety of Azure Virtual Networking topologies such as Hub-Spoke and Virtual WAN with Azure Firewall and third-party Network Virtualization Appliances. For more information, refer to the Azure VMware Solution networking and interconnectivity concepts. The Azure VMware Solution Cloud Adoption Framework also has example network scenarios that can be considered. Design Consideration 9 – Layer 2 Network Extension: VMware HCX can be used to provide Layer 2 network extension functionality to maintain the same IP address schema between sites. Figure 13 – VMware HCX Layer 2 Network Extension with VMware Site Recovery Design Consideration 10 – Anti-Patterns: Try to avoid using these anti-patterns in your recoverability design. Anti-Pattern 1 – Stretched Clusters: Azure VMware Solution Stretched Clusters is the only option for meeting an RPO of 0 requirement. Remember that stretched clusters are considered an availability solution, not disaster recovery, because it is a single fault domain for the management and control plane running in dual Availability Zones (AZs). Azure VMware Solution stretched clusters (GA) currently does not support the VMware Site Recovery add-on. Figure 14 – Azure VMware Solution Private Cloud with Stretched Clusters Anti-Pattern 2 – Ransomware Protection: A Disaster Recovery Automation solution does not provide protection against a ransomware attack. Ransomware protection requires additional security functionality where an isolated and secure area is used to filter through a series of data restores to validate the point in time copy is free from ransomware. This process can take months and it is necessary to access data backups that may be months or years old. This is because the ransomware demand for money is merely the end of a long period of reconnaissance by an attacker and every system needs to be checked for active security vulnerabilities and spyware agents. Disaster Recovery Automation assumes that ransomware is not present, and that data corruption has not replicated to the Disaster Recovery Site. That said, some Disaster Recovery Automation vendors now have a Ransomware Protection feature that can be leveraged as part of the solution. In the following section, I will describe the next steps that would need to be made to progress this high-level design estimate towards a validated detailed design. Next Steps The Azure VMware Solution sizing estimate should be assessed using Azure Migrate. With large enterprise solutions for strategic and major customers, an Azure VMware Solution Solutions Architect from Azure, VMware, or a trusted VMware Partner should be engaged to ensure the solution is correctly sized to deliver business value with the minimum of risk. This should also include an application dependency assessment to understand the mapping between application groups and identify areas of data gravity, application network traffic flows, and network latency dependencies. Summary In this post, we took a closer look at the typical recoverability requirements of a customer workload, the architectural building blocks, and the recoverability design considerations for the Azure VMware Solution. We also discussed the next steps to continue an Azure VMware Solution design.

For the availability design quality, customers will normally have an uptime percentage requirement with an availability zone (AZ) or region requirement that defines each SLA level. For example: SLA Name Uptime AZ/Region Gold 99.999% (5.26 min downtime/year) Dual Regions Silver 99.99% (52.6 min downtime/year) Dual AZs Bronze 99.9% (8.76 hrs downtime/year) Single AZ Table 1 – Typical Customer SLA requirements for Availability A typical legacy business-critical application will have the following application architecture: Load Balancer layer: Uses load balancers to distribute traffic across multiple web servers in the web layer to improve application availability. Web layer: Uses web servers to process client requests made via the secure Hypertext Transfer Protocol (HTTPS). Receives traffic from the load balancer layer and forwards to the application layer.

Receives traffic from the web layer and uses the database layer to access stored data. Database layer: Uses a relational database management service (RDMS) cluster to store data and provide database services to the application layer. Depending upon the availability requirements for the service, the application components could be many and spread across multiple sites and regions to meet the customer SLA. Figure 1 – Typical Legacy Business-Critical Application Architecture In the next section, I will introduce the architectural components of the Azure VMware Solution. Architectural Components The diagram below describes the architectural components of the Azure VMware Solution. Figure 2 – Azure VMware Solution Architectural Components Each Azure VMware Solution architectural component has the following function: Azure Subscription: Used to provide controlled access, budget and quota management for the Azure VMware Solution. Azure Region: Physical locations around the world where we group data centers into Availability Zones (AZs) and then group AZs into regions.

Azure Virtual WAN (vWAN): Aggregates networking, security, and routing functions together into a single unified Wide Area Network (WAN). In the next section, I will describe the availability design considerations for the Azure VMware Solution. Availability Design Considerations The architectural design process takes the business problem to be solved and the business goals to be achieved and distills these into customer requirements, design constraints and assumptions. Design constraints can be characterized by the following three categories: Laws of the Land – data and application sovereignty, governance, regulatory, compliance, etc. Laws of Physics – data and machine gravity, network latency, etc. Laws of Economics – owning versus renting, total cost of ownership (TCO), return on investment (ROI), capital expenditure, operational expenditure, earnings before interest, taxes, depreciation, and amortization (EBITDA), etc. Each design consideration will be a trade-off between the availability, recoverability, performance, manageability, and security design qualities. The desired result is to deliver business value with the minimum of risk by working backwards from the customer problem. Design Consideration 1 – Azure Region and AZs: Azure VMware Solution is available in 30 Azure Regions around the world (US Government has 2 additional Azure Regions). Select the relevant Azure Regions and AZs that meet your geographic requirements. These locations will typically be driven by your design constraints. Design Consideration 2 – Deployment topology: Select the Azure VMware Solution topology that best matches the uptime and geographic requirements of your SLAs. For very large deployments, it may make sense to have separate private clouds dedicated to each SLA for cost efficiency. The Azure VMware Solution supports a maximum of 12 clusters per private cloud. Each cluster supports a minimum of 3 hosts and a maximum of 16 hosts per cluster. Each private cloud supports a maximum of 96 hosts. VMware vSphere HA provides protection against ESXi host failures and VMware vSphere DRS provides distributed resource management. VMware vSphere Fault Tolerance is not supported by the Azure VMware Solution. These features are preconfigured as part of the managed service and cannot be changed by the customer. VMware vCenter Server, VMware HCX Manager, VMware SRM and VMware vSphere Replication Manager are individual appliances and are protected by vSphere HA. VMware NSX Manager is a cluster of 3 unified appliances that have a VM-VM anti-affinity placement policy to spread them across the hosts of the cluster. The VMware NSX Edge cluster is a pair of appliances that also use a VM-VM anti-affinity placement policy. Topology 1 – Standard: The Azure VMware Solution standard private cloud is deployed within a single AZ in an Azure Region, which delivers an infrastructure SLA of 99.9%. Figure 3 – Azure VMware Solution Private Cloud Standard Topology Topology 2 – Multi-AZ: Azure VMware Solution private clouds in separate AZs per Azure Region. VMware HCX is used to connect private clouds across AZs. Application clustering is required to provide the multi-AZ availability mechanism. The customer is responsible for ensuring their application clustering solution is within the limits of bandwidth and latency between private clouds. This topology will deliver an SLA of greater than 99.9%, however it will be dependent upon the application clustering solution used by the customer. The Azure VMware Solution does not support AZ selection during provisioning. This is mitigated by having separate Azure Subscriptions with quota in each separate AZ. You can open a ticket with Microsoft to configure a Special Placement Policy to deploy your Azure VMware Solution private cloud to a particular AZ per subscription. Figure 4 – Azure VMware Solution Private Cloud Multi-AZ Topology Topology 3 – Stretched: The Azure VMware Solution stretched clusters private cloud is deployed across dual AZs in an Azure Region, which delivers a 99.99% infrastructure SLA. This also includes a third AZ for the Azure VMware Solution witness site. Stretched clusters support policy-based synchronous replication to deliver a recovery point objective (RPO) of zero. It is possible to use placement policies and storage policies to mix SLA levels within stretched clusters, by pinning lower SLA workloads to a particular AZ, which will experience downtime during an AZ failure. This feature is GA and is currently only available in Australia East, West Europe, UK South and Germany West Central Azure Regions. Figure 5 – Azure VMware Solution Private Cloud with Stretched Clusters Topology Topology 4 – Multi-Region: Azure VMware Solution private clouds across Azure regions. VMware HCX is used to connect private clouds across Azure Regions. Application clustering is required to provide the multi-region availability mechanism. The customer is responsible for ensuring their application clustering solution is within the limits of bandwidth and latency between private clouds. This topology will deliver an SLA of greater than 99.9%, however it will be dependent upon the application clustering solution used by the customer. An additional enhancement could be using Azure VMware Solution stretched clusters in one or both Azure Regions. Figure 6 – Azure VMware Solution Private Cloud Multi-Region Topology Design Decision 3 – Shared Services or Separate Services Model: The management and control plane cluster (Cluster-1) can be shared with customer workload VMs or be a dedicated cluster for management and control, including customer enterprise services, such as Active Directory, DNS, and DHCP. Additional resource clusters can be added to support customer workload demand. This also includes the option of using separate clusters for each customer SLA. Figure 7 – Azure VMware Solution Shared Services Model Figure 8 – Azure VMware Solution Separate Services Model Design Consideration 4 – SKU type: Three SKU types can be selected for provisioning an Azure VMware Solution private cloud. The smaller AV36 SKU can be used to minimize the impact radius of a failed node. The larger AV36P and AV52 SKUs can be used to run more workloads with less nodes which increases the impact radius of a failed node. The AV36 SKU is widely available in most Azure regions and the AV36P and AV52 SKUs are limited to certain Azure regions. Azure VMware Solution does not support mixing different SKU types within a private cloud (AV64 SKU is the exception). You can check Azure VMware Solution SKU availability by Azure Region here. The AV64 SKU is currently only available for mixed SKU deployments in certain regions. Figure 9 – AV64 Mixed SKU Topology Design Consideration 5 – Placement Policies: Placement policies are used to increase the availability of a service by separating the VMs in an application availability layer across ESXi hosts. When an ESXi failure occurs, it would only impact one VM of a multi-part application layer, which would then restart on another ESXi host through vSphere HA. Placement policies support VM-VM and VM-Host affinity and anti-affinity rules. The vSphere Distributed Resource Scheduler (DRS) is responsible for migrating VMs to enforce the placement policies. To increase the availability of an application cluster, a placement policy with VM-VM anti-affinity rules for each of the web, application and database service layers can be used. Alternatively, VM-Host affinity rules can be used to segment the web, application, and database components to dedicated groups of hosts. The placement policies for stretched clusters can use VM-Host affinity rules to pin workloads to the preferred and secondary sites, if needed. Figure 10 – Azure VMware Solution Placement Policies – VM-VM Anti-Affinity Figure 11 – Azure VMware Solution Placement Policies – VM-Host Affinity Design Consideration 6 – Storage Policies: Table 2 lists the pre-defined VM Storage Policies available for use with VMware vSAN. The appropriate redundant array of independent disks (RAID) and failures to tolerate (FTT) settings per policy need to be considered to match the customer workload SLAs. Each policy has a trade-off between availability, performance, capacity, and cost that needs to be considered. The storage policies for stretched clusters include a designation for the dual site (synchronous replication), preferred site and secondary site policies that need to be considered. To comply with the Azure VMware Solution SLA, you are responsible for using an FTT=2 storage policy when the cluster has 6 or more nodes in a standard cluster. You must also retain a minimum slack space of 25% for backend vSAN operations. Deployment Type Policy Name RAID Failures to Tolerate (FTT) Site Standard RAID-1 FTT-1 1 1 N/A Standard RAID-1 FTT-2 1 2 N/A Standard RAID-1 FTT-3 1 3 N/A Standard RAID-5 FTT-1 5 1 N/A Standard RAID-6 FTT-2 6 2 N/A Standard VMware Horizon 1 1 N/A Stretched RAID-1 FTT-1 Dual Site 1 1 Site mirroring Stretched RAID-1 FTT-1 Preferred 1 1 Preferred Stretched RAID-1 FTT-1 Secondary 1 1 Secondary Stretched RAID-1 FTT-2 Dual Site 1 2 Site mirroring Stretched RAID-1 FTT-2 Preferred 1 2 Preferred Stretched RAID-1 FTT-2 Secondary 1 2 Secondary Stretched RAID-1 FTT-3 Dual Site 1 3 Site mirroring Stretched RAID-1 FTT-3 Preferred 1 3 Preferred Stretched RAID-1 FTT-3 Secondary 1 3 Secondary Stretched RAID-5 FTT-1 Dual Site 5 1 Site mirroring Stretched RAID-5 FTT-1 Preferred 5 1 Preferred Stretched RAID-5 FTT-1 Secondary 5 1 Secondary Stretched RAID-6 FTT-2 Dual Site 6 2 Site mirroring Stretched RAID-6 FTT-2 Preferred 6 2 Preferred Stretched RAID-6 FTT-2 Secondary 6 2 Secondary Stretched VMware Horizon 1 1 Site mirroring Table 2 – VMware vSAN Storage Policies Design Consideration 7 – Network Connectivity: Azure VMware Solution private clouds can be connected using IPSec VPN and Azure ExpressRoute circuits, including a variety of Azure Virtual Networking topologies such as Hub-Spoke and Azure Virtual WAN with Azure Firewall and third-party Network Virtualization Appliances. Multiple Azure ExpressRoute circuits can be used to provide redundant connectivity. VMware HCX also supports redundant Network Extension appliances to provide high availability for Layer-2 network extensions. For more information, refer to the Azure VMware Solution networking and interconnectivity concepts. The Azure VMware Solution Cloud Adoption Framework also has example network scenarios that can be considered. And, if you are interested in Azure ExpressRoute design: Understanding ExpressRoute private peering to address ExpressRoute resiliency ExpressRoute MSEE hairpin design considerations In the following section, I will describe the next steps that would need to be made to progress this high-level design estimate towards a validated detailed design.

Azure VMware Solution Design Series Availability Design Considerations Recoverability Design Considerations Performance Design Considerations Security Design Considerations VMware HCX Design with Azure VMware Solution Overview A global enterprise wants to migrate thousands of VMware vSphere virtual machines (VMs) to Microsoft Azure as part of their application modernization strategy. The first step is to exit their on-premises data centers and rapidly relocate their legacy application VMs to the Azure VMware Solution as a staging area for the first phase of their modernization strategy. What should the Azure VMware Solution look like? Azure VMware Solution is a VMware validated first party Azure service from Microsoft that provides private clouds containing VMware vSphere clusters built from dedicated bare-metal Azure infrastructure. It enables customers to leverage their existing investments in VMware skills and tools, allowing them to focus on developing and running their VMware-based workloads on Azure. In this post, I will introduce the typical customer workload performance requirements, describe the Azure VMware Solution architectural components, and describe the performance design considerations for Azure VMware Solution private clouds. In the next section, I will introduce the typical performance requirements of a customer’s workload. Customer Workload Requirements A typical customer has multiple application tiers that have specific Service Level Agreement (SLA) requirements that need to be met. These SLAs are normally named by a tiering system such as Platinum, Gold, Silver, and Bronze or Mission-Critical, Business-Critical, Production, and Test/Dev. Each SLA will have different availability, recoverability, performance, manageability, and security requirements that need to be met. For the performance design quality, customers will normally have CPU, RAM, Storage and Network requirements. This is normally documented for each application and then aggregated into the total performance requirements for each SLA. For example: SLA Name CPU RAM Storage Network Gold Low vCPU:pCore ratio (<1 to 2), Low VM to Host ratio (1-8) No RAM oversubscription (<=1) High Throughput or High IOPS (for a particular I/O size), Low Latency High Throughput, Low Latency Silver Medium vCPU:pCore ratio (3 to 10), Medium VM to Host ratio (9-15) Medium RAM oversubscription ratio (1.1-1.4) Medium Latency Medium Latency Bronze High vCPU:pCore ratio (10-15), High VM to Host ratio (16+) High RAM oversubscription ratio (1.5-2.5) High Latency High Latency Table 1 – Typical Customer SLA requirements for Performance The performance concepts introduced in Table 1 have the following dimensions: CPU: CPU model and speed (this can be important for legacy single threaded applications), number of cores, vCPU to physical core ratios, CPU Ready times. Memory: Random Access Memory size, Input/Output (I/O) speed and latency, oversubscription ratios. Storage: Capacity, Read/Write Input/Output per Second (IOPS) with Input/Output (I/O) size, Read/Write Throughput, Read/Write Input/Output Latency. Network: In/Out Speed, Network Latency (Round Trip Time). A typical legacy business-critical application will have the following application architecture: Load Balancer layer: Uses load balancers to distribute traffic across multiple web servers in the web layer to improve application availability. Web layer: Uses web servers to process client requests made via the secure Hypertext Transfer Protocol (HTTPS). Receives traffic from the load balancer layer and forwards to the application layer. Application layer: Uses application servers to run software that delivers a business application through a communication protocol. Receives traffic from the web layer and uses the database layer to access stored data. Database layer: Uses a relational database management service (RDMS) cluster to store data and provide database services to the application layer. The application can also be classified as OLTP or OLAP, which have the following characteristics: Online Transaction Processing (OLTP) is a type of data processing that consists of executing several transactions occurring concurrently. For example, online banking, retail shopping, or sending text messages. OLTP systems tend to have a performance profile that is latency sensitive, choppy CPU demands, with small amounts of data being read and written. Online Analytical Processing (OLAP) is a technology that organizes large business databases and supports complex analysis. It can be used to perform complex analytical queries without negatively impacting transactional systems (OLTP). For example, data warehouse systems, business performance analysis, or marketing analysis. OLAP systems tend to have a performance profile that is latency tolerant, requires large amounts of storage for records processing, has a steady state of CPU, RAM and storage throughput. Depending upon the performance requirements for each service, infrastructure design could be a mix of technologies used to meet the different performance SLAs with cost efficiency. Figure 1 – Typical Legacy Business-Critical Application Architecture In the next section, I will introduce the architectural components of the Azure VMware Solution. Architectural Components The diagram below describes the architectural components of the Azure VMware Solution. Figure 2 – Azure VMware Solution Architectural Components Each Azure VMware Solution architectural component has the following function: Azure Subscription: Used to provide controlled access, budget, and quota management for the Azure VMware Solution. Azure Region: Physical locations around the world where we group data centers into Availability Zones (AZs) and then group AZs into regions. Azure Resource Group: Container used to place Azure services and resources into logical groups. Azure VMware Solution Private Cloud: Uses VMware software, including vCenter Server, NSX software-defined networking, vSAN software-defined storage, and Azure bare-metal ESXi hosts to provide compute, networking, and storage resources. Azure NetApp Files, Azure Elastic SAN, and Pure Cloud Block Store are also supported. Azure VMware Solution Resource Cluster: Uses VMware software, including vSAN software-defined storage, and Azure bare-metal ESXi hosts to provide compute, networking, and storage resources for customer workloads by scaling out the Azure VMware Solution private cloud. Azure NetApp Files, Azure Elastic SAN, and Pure Cloud Block Store are also supported. VMware HCX: Provides mobility, migration, and network extension services. VMware Site Recovery: Provides Disaster Recovery automation and storage replication services with VMware vSphere Replication. Third party Disaster Recovery solutions Zerto Disaster Recovery and JetStream Software Disaster Recovery are also supported. Dedicated Microsoft Enterprise Edge (D-MSEE): Router that provides connectivity between Azure cloud and the Azure VMware Solution private cloud instance. Azure Virtual Network (VNet): Private network used to connect Azure services and resources together. Azure Route Server: Enables network appliances to exchange dynamic route information with Azure networks. Azure Virtual Network Gateway: Cross premises gateway for connecting Azure services and resources to other private networks using IPSec VPN, ExpressRoute, and VNet to VNet. Azure ExpressRoute: Provides high-speed private connections between Azure data centers and on-premises or colocation infrastructure. Azure Virtual WAN (vWAN): Aggregates networking, security, and routing functions together into a single unified Wide Area Network (WAN). In the next section, I will describe the performance design considerations for the Azure VMware Solution. Performance Design Considerations The architectural design process takes the business problem to be solved and the business goals to be achieved and distills these into customer requirements, design constraints and assumptions. Design constraints can be characterized by the following three categories: Laws of the Land – data and application sovereignty, governance, regulatory, compliance, etc. Laws of Physics – data and machine gravity, network latency, etc. Laws of Economics – owning versus renting, total cost of ownership (TCO), return on investment (ROI), capital expenditure, operational expenditure, earnings before interest, taxes, depreciation, and amortization (EBITDA), etc. Each design consideration will be a trade-off between availability, recoverability, performance, manageability, and security design qualities. The desired result is to deliver business value with the minimum of risk by working backwards from the customer problem. Design Consideration 1 – Azure Region: Azure VMware Solution is available in 30 Azure Regions around the world (US Government has 2 additional Azure Regions). Select the relevant Azure Regions that meet your geographic requirements. These locations will typically be driven by your design constraints and the required Azure services that will be dependent upon the Azure VMware Solution. For highest throughput and lowest network latency, the Azure VMware Solution and dependent Azure services such as third-party backup/recovery and Azure NetApp Filer volumes should be placed in the same Availability Zone in an Azure Region. Unfortunately, the Azure VMware Solution does not have a Placement Policy Group feature to allow Azure services to be automatically deployed in the same Availability Zone. You can open a ticket with Microsoft to configure a Special Placement Policy to deploy your Azure VMware Solution private cloud to a particular AZ to ensure that your Azure services are placed as closely together as possible. In addition, the proximity of the Azure Region to the remote users and applications consuming the service should also be considered for network latency and throughput. Figure 3 – Azure VMware Solution Availability Zone Placement for Performance Design Consideration 2 – SKU type: Table 2 lists the three SKU types can be selected for provisioning an Azure VMware Solution private cloud. Depending upon the workload performance requirements, the AV36 and AV36P nodes can be used for general purpose compute and the AV52 nodes can be used for compute intensive and storage heavy workloads. The AV36 SKU is widely available in most Azure regions and the AV36P and AV52 SKUs are limited to certain Azure regions. Azure VMware Solution does not support mixing different SKU types within a private cloud (AV64 SKU is the exception). You can check Azure VMware Solution SKU availability by Azure Region here. The AV64 SKU is currently only available for mixed SKU deployments in certain regions. Figure 4 – AV64 Mixed SKU Topology Currently, Azure VMware Solution does not have SKUs that support GPU hardware. The Azure VMware Solution does not natively support Auto-Scale, however you can use this Auto-Scale function instead. For more information, refer to SKU types. SKU Type Purpose CPU (Cores/GHz) RAM (GB) vSAN Cache Tier (TB, raw) vSAN Capacity Tier (TB, raw) Network Interface Cards AV36 General Purpose Compute Dual Intel Xeon Gold 6140 CPUs (Skylake microarchitecture) with 18 cores/CPU @ 2.3 GHz, Total 36 physical cores (72 logical cores with hyperthreading) 576 3.2 (NVMe) 15.20 (SSD) 4x 25 Gb/s NICs (2 for management & control plane, 2 for customer traffic) AV36P General Purpose Compute Dual Intel Xeon Gold 6240 CPUs (Cascade Lake microarchitecture) with 18 cores/CPU @ 2.6 GHz / 3.9 GHz Turbo, Total 36 physical cores (72 logical cores with hyperthreading) 768 1.5 (Intel Cache) 19.20 (NVMe) 4x 25 Gb/s NICs (2 for management & control plane, 2 for customer traffic) AV52 Compute/Storage heavy workloads Dual Intel Xeon Platinum 8270 CPUs (Cascade Lake microarchitecture) with 26 cores/CPU @ 2.7 GHz / 4.0 GHz Turbo, Total 52 physical cores (104 logical cores with hyperthreading) 1,536 1.5 (Intel Cache) 38.40 (NVMe) 4x 25 Gb/s NICs (2 for management & control plane, 2 for customer traffic) AV64 General Purpose Compute Dual Intel Xeon Platinum 8370C CPUs (Ice Lake microarchitecture) with 32 cores/CPU @ 2.8 GHz / 3.5 GHz Turbo, Total 64 physical cores (128 logical cores with hyperthreading) 1,024 3.84 (NVMe) 15.36 (NVMe) 1x 100 Gb/s Table 2 – Azure VMware Solution SKUs Design Consideration 3 – Deployment topology: Select the Azure VMware Solution topology that best matches the performance requirements of your SLAs. For very large deployments, it may make sense to have separate private clouds dedicated to each SLA for optimum performance. The Azure VMware Solution supports a maximum of 12 clusters per private cloud. Each cluster supports a minimum of 3 hosts and a maximum of 16 hosts per cluster. Each private cloud supports a maximum of 96 hosts. VMware vCenter Server, VMware HCX Manager, VMware SRM and VMware vSphere Replication Manager are individual appliances that run in Cluster-1. VMware NSX Manager is a cluster of 3 unified appliances that have a VM-VM anti-affinity placement policy to spread them across the hosts of the cluster. The VMware NSX Edge cluster is a pair of appliances that also use a VM-VM anti-affinity placement policy. All northbound customer traffic traverses the NSX Edge cluster. All vSAN storage traffic traverses the VLAN-backed Portgroup of the Management vSphere Distributed Switch, which is part of the management and control plane. The management and control plane cluster (Cluster-1) can be shared with customer workload VMs or be a dedicated cluster for management and control, including customer enterprise services, such as Active Directory, DNS, & DHCP. Additional resource clusters can be added to support customer demand. This also includes the option of using dedicated clusters for each customer SLA. Topology 1 – Mixed: Run mixed SLA workloads in each cluster of the Azure VMware Solution private cloud. Figure 5 – Azure VMware Solution Mixed Workloads Topology Topology 2 – Dedicated Clusters: Use separate clusters for each SLA in the Azure VMware Solution private cloud. Figure 6 – Azure VMware Solution Dedicated Clusters Topology Topology 3 – Dedicated Private Clouds: Use dedicated Azure VMware Solution private clouds for each SLA for optimum performance. Figure 7 – Azure VMware Solution Dedicated Private Cloud Instances Topology Design Consideration 4 – Network Connectivity: Azure VMware Solution private clouds can be connected using IPSec VPN and Azure ExpressRoute circuits, including a variety of Azure Virtual Networking topologies such as Hub-Spoke and Azure Virtual WAN with Azure Firewall and third-party Network Virtualization Appliances. Azure Public IP connectivity with NSX is also available. From a performance perspective, Azure ExpressRoute and AVS Interconnect should be used instead of Azure Virtual WAN and IPSec VPN. The following design considerations (5-9) elaborate on network performance design. For more information, refer to the Azure VMware Solution networking and interconnectivity concepts. The Azure VMware Solution Cloud Adoption Framework also has example network scenarios that can be considered. Design Consideration 5 – Azure VNet Connectivity: Use FastPath for connecting an Azure VMware Solution private cloud to an Azure VNet for highest throughput and lowest latency. For maximum performance between Azure VMware Solution and Azure native services, a VNet Gateway with the Ultra performance or ErGw3AZ SKU is needed to enable the Fast Path feature when creating the connection. FastPath is designed to improve the data path performance to your VNet. When enabled, FastPath sends network traffic directly to virtual machines in the VNet, bypassing the gateway, resulting in 10 Gbps or higher throughput. For more information, refer to Azure ExpressRoute FastPath. Figure 8 – Azure VMware Solution connected to VNet Gateway with FastPath Design Consideration 6 – Intra-region Connectivity: Use AVS Interconnect for connecting Azure VMware Solution private clouds together in the same Azure Region for the highest throughput and lowest latency. You can select Azure VMware Solution private clouds from another Azure Subscription or Azure Resource Group, the only constraint is it must be in the same Azure Region. A maximum of 10 private clouds can be connected per private cloud instance. For more information, refer to AVS Interconnect. Figure 9 – Azure VMware Solution with AVS Interconnect Design Consideration 7 – Inter-region/On-Premises Connectivity: Use ExpressRoute Global Reach for connecting Azure VMware Solution private clouds together in different Azure Regions or to on-premises vSphere environments for the highest throughput and lowest latency. For more information, refer to Azure VMware Solution network design considerations. Figure 10 – Azure VMware Solution with ExpressRoute Global Reach Figure 11 – Azure VMware Solution with ExpressRoute Global Reach to On-premises vSphere infrastructure Design Consideration 8 – Host Connectivity: Use NSX Multi-Edge to increase the throughput of north/south traffic from the Azure VMware Solution private cloud. This configuration is available for a management cluster (Cluster-1) with four or more nodes. The additional Edge VMs are added to the Edge Cluster and increase the amount of traffic that can be forwarded through the 25Gbps uplinks across the ESXi hosts. This feature needs to be configured by opening an SR. For more information, refer to Azure VMware Solution network design considerations. Figure 12 – Azure VMware Solution Multi-Edge with NSX Design Consideration 9 – Internet Connectivity: Use Public IP on the NSX Edge if high speed internet access direct to the Azure VMware Solution private cloud is needed. This allows you to bring an Azure-owned Public IPv4 address range directly to the NSX Edge for consumption. You should configure this public range on a network virtual appliance (NVA) to secure the private cloud. For more information, refer to Internet Connectivity Design Considerations. Figure 13 – Azure VMware Solution Public IP Address with NSX Design Consideration 10 – VM Optimization: Use VM Hardware tuning, and Resource Pools to provide peak performance for workloads. VMware vSphere Virtual Machine Hardware should be optimized for the required performance: vNUMA optimization for CPU and RAM Shares Reservations & Limits Latency Sensitive setting Paravirtual network & storage adapters Multiple SCSI controllers Spread vDisks across SCSI controllers Resource Pools can be used to apply CPU and RAM QoS policies for each SLA running in a mixed cluster. For more information, refer to Performance Best Practices. Design Consideration 11 – Placement Policies: Placement policies can be used to increase the performance of a service by separating the VMs in an application availability layer across ESXi hosts. This allows you to pin workloads to a particular host for exclusive access to CPU and RAM resources. Placement policies support VM-VM and VM-Host affinity and anti-affinity rules. The vSphere Distributed Resource Scheduler (DRS) is responsible for migrating VMs to enforce the placement policies. For more information, refer to Placement Policies. Figure 14 – Azure VMware Solution Placement Policies Design Consideration 12 – External Datastores: Use a first-party or third-party storage solution to offload lower SLA workloads from VMware vSAN into a separate tier of storage. Azure VMware Solution supports attaching Azure NetApp Files as Network File System (NFS) datastores for offloading virtual machine storage from VMware vSAN. This allows the VMware vSAN datastore to be dedicated to Gold SLA virtual machines. Azure VMware Solution also supports the use of Azure Elastic SAN and Pure Cloud Block Stores as attached iSCSI datastores. For more information, refer to Azure NetApp Files datastores. Figure 15 – Azure VMware Solution External Datastores with Azure NetApp Files Design Consideration 13 – Storage Policies: Table 3 lists the pre-defined VM Storage Policies available for use with VMware vSAN. The appropriate redundant array of independent disks (RAID) and failures to tolerate (FTT) settings per policy need to be considered to match the customer workload SLAs. Each policy has a trade-off between availability, performance, capacity, and cost that needs to be considered. The highest performing VM Storage Policy for enterprise workloads is the RAID-1 policy. To comply with the Azure VMware Solution SLA, you are responsible for using an FTT=2 storage policy when the cluster has 6 or more nodes in a standard cluster. You must also retain a minimum slack space of 25% for backend vSAN operations. For more information, refer to Configure Storage Policy. Deployment Type Policy Name RAID Failures to Tolerate (FTT) Site Standard RAID-1 FTT-1 1 1 N/A Standard RAID-1 FTT-2 1 2 N/A Standard RAID-1 FTT-3 1 3 N/A Standard RAID-5 FTT-1 5 1 N/A Standard RAID-6 FTT-2 6 2 N/A Standard VMware Horizon 1 1 N/A Table 3 – VMware vSAN Storage Policies Design Consideration 14 – Mobility: VMware HCX can be tweaked to improve throughput and performance. VMware HCX Manager can be upsized through Run Command. The number of network extension (NE) instances can be increased to allow Portgroups to be distributed over instances to increase layer 2 extension (L2E) performance. You can also establish a dedicated Mobility Cluster, accompanied by a dedicated Service Mesh for each distinct workload cluster, thereby increasing mobility performance. The Azure VMware Solution supports a maximum of 10 service meshes per private cloud, this is due to the allocation of the /22 management IP schema. Application Path Resiliency & TCP Flow Conditioning are also options that can be enabled to improve mobility performance. TCP Flow Conditioning dynamically optimizes the segment size for traffic traversing the Network Extension path. Application Path Resiliency technology creates multiple Foo-Over-UDP (FOU) tunnels between the source and destination Uplink IP pair for improved performance, resiliency, and path diversity. For more information, refer to VMware HCX Best Practices. Figure 16 – VMware HCX with Dedicated Mobility Cluster Design Consideration 15 – Anti-Patterns: Try to avoid using these anti-patterns in your performance design. Anti-Pattern 1 – Stretched Clusters: Azure VMware Solution Stretched Clusters should primarily be used to meet a Multi-AZ or Recovery Point Objective of zero requirement. If stretched clusters are used, there will be a write throughput and write latency impact for all synchronous writes using the site mirroring storage policy. For more information, refer to Stretched Clusters. Figure 17 – Azure VMware Solution Private Cloud with Stretched Clusters In the following section, I will describe the next steps that need to be made to progress this high-level design estimate towards a validated detailed design. Next Steps The Azure VMware Solution sizing estimate should be assessed using Azure Migrate. With large enterprise solutions for strategic and major customers, an Azure VMware Solution Solutions Architect from Azure, VMware, or a trusted VMware Partner should be engaged to ensure the solution is correctly sized to deliver business value with the minimum of risk. This should also include an application dependency assessment to understand the mapping between application groups and identify areas of data gravity, application network traffic flows, and network latency dependencies. Summary In this post, we took a closer look at the typical performance requirements of a customer workload, the architectural building blocks, and the performance design considerations for the Azure VMware Solution. We also discussed the next steps to continue an Azure VMware Solution design.

In this post, I will introduce the typical customer workload security requirements, describe the Azure VMware Solution architectural components, describe the zero trust security model, and describe the security design considerations for Azure VMware Solution private clouds. In the next section, I will introduce the typical security requirements of a customer’s workload. Customer Workload Requirements A typical customer has multiple application tiers that have specific Service Level Agreement (SLA) requirements that need to be met. These SLAs are normally named by a tiering system such as Platinum, Gold, Silver, and Bronze or Mission-Critical, Business-Critical, Production, and Test/Dev. Each SLA will have different availability, recoverability, performance, manageability, and security requirements that need to be met. For the security design quality, customers will normally have governance, regulatory, and compliance requirements. This is normally documented for each application and then aggregated into the information security policy requirements for each SLA or line of business. For example: Line of Business Governance, Regulatory, & Compliance Finance ISO/IEC 27001:2022, GLBA, PCI DSS 4.0 US Government NIST Cybersecurity Framework, FISMA, FedRAMP Health Care ISO/IEC 27001:2022, HIPAA, PCI DSS 4.0 Table 1 – Typical Customer requirements for Information Security The security concepts introduced in Table 1 have the following definitions: Governance: The process of making and enforcing decisions within an IT organization or system. It encompasses decision-making, rule-setting, and enforcement mechanisms to guide the functioning of IT in alignment with the business goals and strategies. Regulatory: The set of laws, regulations, and guidelines that govern the collection, storage, processing, and sharing of sensitive information. These regulations are designed to ensure that organizations protect sensitive information from unauthorized access, use, disclosure, and destruction. Compliance with these regulations is mandatory and non-compliance can result in legal penalties, fines, and reputational damage. Compliance: The act or process of following the rules, regulations, and standards that apply to the IT organization or system. It can also refer to the ability of an IT system to adapt to changing requirements or demands. A typical legacy business-critical application will have the following application architecture: Load Balancer layer: Uses load balancers to distribute traffic across multiple web servers in the web layer to improve application availability. Web layer: Uses web servers to process client requests made via the secure Hypertext Transfer Protocol (HTTPS). Receives traffic from the load balancer layer and forwards to the application layer. Application layer: Uses application servers to run software that delivers a business application through a communication protocol. Receives traffic from the web layer and uses the database layer to access stored data. Database layer: Uses a relational database management service (RDMS) cluster to store data and provide database services to the application layer. Depending upon the security requirements for each service, infrastructure design could be a mix of technologies used to meet the different security policies with cost efficiency. Figure 1 – Typical Legacy Business-Critical Application Architecture In the next section, I will introduce the architectural components of the Azure VMware Solution. Architectural Components The diagram below describes the architectural components of the Azure VMware Solution. Figure 2 – Azure VMware Solution Architectural Components Each Azure VMware Solution architectural component has the following function: Azure Subscription: Used to provide controlled access, budget, and quota management for the Azure VMware Solution. Azure Region: Physical locations around the world where we group data centers into Availability Zones (AZs) and then group AZs into regions. Azure Resource Group: Container used to place Azure services and resources into logical groups. Azure VMware Solution Private Cloud: Uses VMware software, including vCenter Server, NSX software-defined networking, vSAN software-defined storage, and Azure bare-metal ESXi hosts to provide compute, networking, and storage resources. Azure NetApp Files, Azure Elastic SAN, and Pure Cloud Block Store are also supported. Azure VMware Solution Resource Cluster: Uses VMware software, including vSAN software-defined storage, and Azure bare-metal ESXi hosts to provide compute, networking, and storage resources for customer workloads by scaling out the Azure VMware Solution private cloud. Azure NetApp Files, Azure Elastic SAN, and Pure Cloud Block Store are also supported. VMware HCX: Provides mobility, migration, and network extension services. VMware Site Recovery: Provides Disaster Recovery automation and storage replication services with VMware vSphere Replication. Third party Disaster Recovery solutions Zerto Disaster Recovery and JetStream Software Disaster Recovery are also supported. Dedicated Microsoft Enterprise Edge (D-MSEE): Router that provides connectivity between Azure cloud and the Azure VMware Solution private cloud instance. Azure Virtual Network (VNet): Private network used to connect Azure services and resources together. Azure Route Server: Enables network appliances to exchange dynamic route information with Azure networks. Azure Virtual Network Gateway: Cross premises gateway for connecting Azure services and resources to other private networks using IPSec VPN, ExpressRoute, and VNet to VNet. Azure ExpressRoute: Provides high-speed private connections between Azure data centers and on-premises or colocation infrastructure. Azure Virtual WAN (vWAN): Aggregates networking, security, and routing functions together into a single unified Wide Area Network (WAN). In the next section, I will introduce the Zero Trust Security Model which should be used as the framework for securing your Azure cloud resources. Zero Trust Security Model A holistic approach to Zero Trust should extend to your entire digital estate: inclusive of identities, endpoints, network, data, apps, and infrastructure. Zero Trust architecture serves as a comprehensive end-to-end strategy and requires integration across the elements. The foundation of Zero Trust security is identities. Both human and non-human identities need strong authorization, connecting from either personal or corporate endpoints with compliant devices, requesting access based on strong policies grounded in Zero Trust principles of explicit verification, least-privilege access, and assumed breach. As a unified policy enforcement, the Zero Trust policy intercepts the request, explicitly verifies signals from all six foundational elements based upon policy configuration and enforces least-privilege access. Signals include the role of the user, location, device compliance, data sensitivity, and application sensitivity. In addition to telemetry and state information, the risk assessment from threat protection feeds into the policy engine to automatically respond to threats in real time. Policy is enforced at the time of access and continuously evaluated throughout the session. This policy is further enhanced by policy optimization. Governance and compliance are critical to a strong Zero Trust implementation. Security posture assessment and productivity optimization are necessary to measure the telemetry throughout the services and systems. Telemetry and analytics feeds into the threat protection system. Large amounts of telemetry and analytics enriched by threat intelligence generate high-quality risk assessments that can be either manually investigated or automated. Attacks happen at cloud speed and, because humans can’t react quickly enough or sift through all the risks, your defense systems must also act at cloud speed. The risk assessment feeds into the policy engine for real-time automated threat protection and additional manual investigation if needed. Traffic filtering and segmentation is applied to the evaluation and enforcement from the Zero Trust policy before access is granted to any public or private network. Data classification, labeling, and encryption should be applied to emails, documents, and structured data. Access to apps should be adaptive, whether SaaS or on-premises. Runtime control is applied to infrastructure with serverless, containers, IaaS, PaaS, and internal sites with just-in-time (JIT) and version controls actively engaged. Finally, telemetry, analytics, and assessment from the network, data, apps, and infrastructure are fed back into the policy optimization and threat protection systems. Figure 3 – Zero Trust Security Model Many legacy monolithic application stacks may use the older defense in depth security model, however, we introduced the zero trust security model here for consideration. For more information, refer to the Microsoft Security Adoption Framework, and the Microsoft Cybersecurity Reference Architectures. In the next section, I will describe the security design considerations for the Azure VMware Solution. Security Design Considerations The architectural design process takes the business problem to be solved and the business goals to be achieved and distills these into customer requirements, design constraints and assumptions. Design constraints can be characterized by the following three categories: Laws of the Land – data and application sovereignty, governance, regulatory, compliance, etc. Laws of Physics – data and machine gravity, network latency, etc. Laws of Economics – owning versus renting, total cost of ownership (TCO), return on investment (ROI), capital expenditure, operational expenditure, earnings before interest, taxes, depreciation, and amortization (EBITDA), etc. Each design consideration will be a trade-off between availability, recoverability, performance, manageability, and security design qualities. The desired result is to deliver business value with the minimum of risk by working backwards from the customer problem. Design Consideration 1 – Governance, Regulatory, & Compliance: Learn how Microsoft cloud services protect your data, and how you can manage cloud data security and compliance for your organization with these certifications, regulations, and standards. Also included are reports, whitepapers, artifacts, and industry/regional resources. You can also use the Microsoft cloud security benchmark to address the common challenges customers have when securing their Azure infrastructure. For more information visit Security, governance, and compliance disciplines for Azure VMware Solution. Design Consideration 2 – Azure Region: Select the relevant Azure Regions that meet your governance, regulatory, and compliance requirements. Azure VMware Solution is available in 30 Azure Regions around the world. Azure VMware Solution is also available in two Azure Government regions and in scope for FedRAMP HIGH authorization. Azure VMware Solution in Azure Government is currently pending authorization for DoD IL4/IL5. Design Consideration 3 – Identity & Access Management: Use role-based access control to provide secure access to the Azure VMware Solution. Use Microsoft Entra Privileged Identity Management to allow time-bound access to the Azure portal and control pane operations. Use privileged identity management audit history to track operations that highly privileged accounts perform. For more information refer to Security considerations for Azure VMware Solution workloads and Enterprise-scale identity and access management. Design Consideration 4 – LDAPS Integration: Select an external identity source for your Azure VMware Solution. The local cloud administrator user accounts for vCenter Server and NSX Manager should be used as emergency access accounts for "break glass" scenarios in your private cloud. It's not intended to be used for daily administrative activities or for integration with other services. Use an external identity source to give your administrators and operators access to the Azure VMware Solution. This allows them to use their corporate credentials when accessing the Azure VMware Solution. For more information refer to Identity and access. This MTC blog post also provides a detailed procedure to Configure LDAPS within Azure VMware Solution. Design Consideration 5 – SIEM Logging: Select the Azure VMware Solution Diagnostic setting to stream platform logs and metrics to your Security Information & Event Management (SIEM) solution. Azure VMware Solution supports Azure Log Analytics, Azure Event Hub, and Azure Blob Storage as logging targets. The log stream contains the following: vCenter Server logs ESXi logs vSAN logs NSX Manager logs NSX Data Center Distributed Firewall logs NSX Data Center Gateway Firewall logs NSX Data Center Edge Appliance logs The Azure VMware Solution does not currently support Syslog Forwarding to a customer Syslog server, however you can use this Syslog Forwarding function instead. For more information refer to Configure VMware syslogs for Azure VMware Solution. Figure 4 – Azure VMware Solution Logging Options Design Consideration 6 – VMware vSAN Encryption: Use a Customer Managed Key to augment the Azure VMware Solution vSAN encryption process. Customer-managed keys give you control over the encrypted vSAN data on Azure VMware Solution. You can use Azure Key Vault to generate customer managed keys and centralize the key management process. For more information refer to Configure customer-managed key encryption at rest in Azure VMware Solution. Figure 5 – Customer Managed Keys with Azure VMware Solution Design Consideration 7 – VM Security: Use Trusted Launch with Azure VMware Solution to increase the security of your Virtual Machines. Trusted Launch comprises of Secure Boot, Virtual Trusted Platform Module (vTPM), and Virtualization-based Security (VBS) to provide a formidable defense against modern cyber threats. Trusted Launch is a requirement for Windows 11 compatibility. For more information refer to Trusted Launch for Azure VMware Solution virtual machines. Design Consideration 8 – Firewall Placement: Select the placement locations of network security firewalls within the Azure VMware Solution or Azure native services, including the zones of trust topology to meet your traffic flow requirements. Zones of trust refer to the concept of segmenting a network into different areas based upon the level of trust assigned to the devices and users within that area. This is used as part of the Zero Trust security model, where access to resources is granted on a need-to-know basis and is strictly enforced through continuous authentication and authorization. Traffic flows refer to the movement of data between different zones of trust in a network. Understanding traffic flows is important for network design, capacity planning, and information security. For Azure VMware Solution, the zones of trust need to account for the Azure VMware Solution private clouds, Azure native services, the internet, and other non-Azure locations. Figure 6 – Zones of Trust There are four options in the Azure Cloud Adoption Framework that describe different ways to secure and manage the network traffic between the Azure VMware Solution and other Azure resources, on-premises, and the internet: Option 1: Use a Secured Virtual WAN hub with default route propagation to route all traffic through an Azure Firewall or a third-party security provider. Option 2: Use Network Virtual Appliances in Azure Virtual Network to inspect all network traffic and apply firewall rules or policies. Option 3: Egress from Azure VMware Solution with or without NSX or NVA to control the outbound traffic from Azure VMware Solution to other destinations. Option 4: Use third-party firewall solutions in a hub virtual network with Azure Route Server to enable dynamic routing between Azure VMware Solution and the firewall appliances. Each option has its own benefits and trade-offs depending upon your requirements and preferences. In addition, we have VMware NSX features that can be used to secure north-south and east-west traffic, including the optional use of host-based endpoint solutions. Figure 7 – Azure Firewall and 3 rd party NVA options Option 1 – Secured Virtual WAN hub: Use a Secured Virtual WAN hub with default route propagation to route all traffic through an Azure Firewall or a third-party security provider. This solution doesn't work for on-premises filtering and Global Reach bypasses the Virtual WAN hubs. For more information refer to Azure Cloud Adoption Framework. Figure 8 – Option 1: Secured Virtual WAN hub Option 2 – Third-party Firewalls for all traffic: Use Network Virtual Appliances in Azure Virtual Network to inspect all network traffic and apply firewall rules or policies. Choose this option if you want to use your existing NVA and centralize all traffic inspection in your hub virtual network. For more information refer to Azure Cloud Adoption Framework. Figure 9 – Option 2: Third-party Firewalls for all traffic The diagram below provides an example of how FortiNet FortiGate NVAs can be used to build Scenario 2. For more information refer to Azure routing and network interfaces. Figure 10 – Example design of Option 2 with FortiNet FortiGate NVAs Option 3 – Egress from Azure VMware Solution: Egress from Azure VMware Solution with or without NSX or an NVA to control the outbound traffic from Azure VMware Solution to other destinations. Choose this option if you need to inspect traffic from two or more Azure VMware Solution private clouds. This option lets you use NSX native features. You can also combine this option with NVAs running on Azure VMware Solution between Tier-0 and Tier-1 Gateways. For more information refer to Azure Cloud Adoption Framework. Figure 11 – Option 3: Egress from Azure VMware Solution Option 4 – Third-party Firewall for internet traffic: Use a third-party firewall solution in a hub virtual network with Azure Route Server to enable dynamic routing between Azure VMware Solution and the firewall appliances. Choose this option to advertise the default route from an NVA in your Azure hub virtual network to an Azure VMware Solution. For more information refer to Azure Cloud Adoption Framework. Figure 12 – Option 4: Third-party Firewall for internet traffic Option 5 – NSX Gateways: Use NSX Gateways to secure North-South network traffic. You can use the network filtering capabilities of the Tier-0 and Tier-1 Gateways in NSX to provide North-South traffic filtering. For more information refer to Azure VMware Solution Network Security. Figure 13 – VMware NSX Gateway Firewall policies for North-South traffic Option 6 – Micro segmentation with DFW: Use NSX Distributed Firewall to secure East-West network traffic. You can use the Distributed Firewall in NSX to provide East-West micro segmentation of traffic flows. For more information refer to Azure VMware Solution Network Security. Figure 14 – VMware NSX Micro-segmentation (DFW) for East-West traffic Option 7 – Microsoft Defender for Cloud: Use a Microsoft Defender for Cloud or a third-party host-based security solution to secure your traffic from the guest operating system. Microsoft Defender for Cloud provides advanced threat protection across your Azure VMware Solution and on-premises virtual machines (VMs). It assesses the vulnerability of Azure VMware Solution VMs and raises alerts as needed. These security alerts can be forwarded to Azure Monitor for resolution. You can define security policies in Microsoft Defender for Cloud. For more information refer to Integrate Microsoft Defender for Cloud with Azure VMware Solution. Figure 15 – Microsoft Defender for Cloud with Azure VMware Solution Design Consideration 9 – Internet Access: Azure VMware Solution has three options within each private cloud instance that can be configured. These are explicitly described separate from the firewall scenarios in Design Consideration 8 even though they overlap. Option 1 – Internet Disabled: Use Azure native networking to provide internet access. There are multiple ways to generate a default route in Azure and send it towards your Azure VMware Solution private cloud or on-premises. The options are as follows: An Azure firewall in a Virtual WAN Hub. A third-party Network Virtual Appliance in a Virtual WAN Hub Spoke Virtual Network. A third-party Network Virtual Appliance in a Native Azure Virtual Network using Azure Route Server. A default route from on-premises transferred to Azure VMware Solution over Global Reach. For more information refer to Internet connectivity design considerations. Figure 16 – Azure VMware Solution Internet Disabled Option 2 – Managed SNAT: Managed SNAT service provides a simple method for outbound internet access from an Azure VMware Solution private cloud. Features of Managed SNAT include the following: Easily enabled. No control over SNAT rules, all sources that reach the SNAT service are allowed. No visibility of connection logs. Two Public IPs are used and rotated to support up to 128k simultaneous outbound connections. No inbound DNAT capability is available. For more information refer to Internet connectivity design considerations. Figure 17 – Azure VMware Solution Managed SNAT Internet Access Option 3 – Public IP Address (PIP): Use an allocated Azure Public IPv4 address directly with the NSX Edge for consumption. PIP allows the Azure VMware Solution private cloud to directly consume and apply public network addresses in NSX as required. These addresses are used for the following types of connections: Outbound SNAT Inbound DNAT Load balancing using VMware NSX Advanced Load Balancer and other third-party Network Virtual Appliances Applications directly connected to a workload VM interface. This option also lets you configure the public address on a third-party Network Virtual Appliance to create a DMZ within the Azure VMware Solution private cloud. The Azure Public IP addresses are customer owned and are not actively scanned by Microsoft. Microsoft Defender for Cloud or a suitable 3 rd party solution should be used fully secure the internet connection. These options are discussed in Design Consideration 8. For more information refer to Internet connectivity design considerations. Figure 18 – Azure VMware Solution VMware NSX Public IP Address (PIP) The use of a “T1 Sandwich” with a third-party NVA, allows you to scale beyond the 10 vNIC limitation for VMware vSphere virtual machine hardware. The result is an increase in the number of networks you can protect with an NVA. The diagram below provides an example of how a CheckPoint NVA can be used with a T1 Sandwich topology. Figure 19 – VMware NSX T1 Gateway Sandwich with CheckPoint In the following section, I will describe the next steps that need to be made to progress this high-level design estimate towards a validated detailed design. Next Steps The Azure VMware Solution sizing estimate should be assessed using Azure Migrate. With large enterprise solutions for strategic and major customers, an Azure VMware Solution Solutions Architect from Azure, VMware, or a trusted VMware Partner should be engaged to ensure the solution is correctly sized to deliver business value with the minimum of risk. This should also include an application dependency assessment to understand the mapping between application groups and identify areas of data gravity, application network traffic flows, and network latency dependencies. Summary In this post, we took a closer look at the typical security requirements of a customer workload, the architectural building blocks, the zero trust security model, and the security design considerations for the Azure VMware Solution. We also discussed the next steps to continue an Azure VMware Solution design.

Azure VMware Solution encryption with customer-managed keys is now Generally Available. Customer-managed keys give customers maximum control over their encrypted vSAN data on Azure VMware Solution. With this feature, customers can use Azure Key Vault to generate customer managed keys and centralize the key management process. Azure VMware Solution is a VMware validated first party Azure service from Microsoft that provides private clouds containing VMware vSphere clusters built from dedicated bare-metal Azure infrastructure. It enables customers to leverage their existing investments in VMware skills and tools, allowing them to focus on developing and running their VMware-based workloads on Azure. Azure VMware Solution provides default data at rest encryption for private cloud’s vSAN datastore, and it is performed with service-managed keys, automatically and transparently managed by Microsoft. However, many industries require data that not only encrypted data at rest but do so by using encryption keys that customers have full control over as per regulations and compliance requirement. Customer-managed keys don’t disable default vSAN datastore encryption. Instead, they add a second layer of encryption on top of the default one. This means that customer-managed keys also deliver double encryption, a feature that is sometimes part of the same compliance requirements. Azure VMware Solution customers need to enable system-assigned managed identity on their private cloud to access keys within customer owned Azure Key Vault. A user with required permission on Azure Key Vault must first grant Get, wrap key, and unwrap key permissions to private cloud managed identity. Customer can revoke access anytime by removing Azure VMware Solution’s access to customer-owned Azure Key Vault or disabling keys used for private cloud encryption, making it impossible for Azure VMware Solution to read or write any data within customer’s private cloud. Moreover, customers can use Azure Key Vault monitoring to ensure only Azure VMware Solution is accessing keys. Benefits Full control of data access via the ability to remove the key and make the private cloud data inaccessible. Full control over the key lifecycle, including rotation of the key to aligning with corporate policies.

Azure VMware Solution proudly introduces Public Preview of Trusted Launch for Virtual Machines. This advanced feature comprises Secure Boot, Virtual Trusted Platform Module (vTPM), and Virtualization-based Security (VBS), collectively forming a formidable defense against modern cyber threats. In today's digitally connected world, security is paramount. Organizations rely heavily on virtual machines (VMs) to run critical workloads, and ensuring the integrity and security of these VMs is a top priority. This not only paves the way for Windows 11 compatibility by fulfilling vTPM prerequisites but also significantly elevates security and functionality for a myriad of operating systems. Let's explore how Trusted Launch is raising the bar and setting a new standard in VM security. Azure VMware Solution is a VMware validated first party Azure service from Microsoft that provides private clouds containing VMware vSphere clusters built from dedicated bare-metal Azure infrastructure. It enables customers to leverage their existing investments in VMware skills and tools, allowing them to focus on developing and running their VMware-based workloads on Azure. Understanding Trusted Launch At its core, Trusted Launch is a comprehensive security solution that encompasses three key components: Secure Boot, Virtual Trusted Platform Module (vTPM), and Virtualization-based security (VBS). Each of these components plays a vital role in fortifying the security posture of VMs. 1. Secure Boot: The Foundation of Trust Secure Boot is the first line of defense in Trusted Launch. It establishes a "root of trust" for VMs by ensuring that only signed operating systems and drivers are allowed to boot. This prevents the installation of malware-based rootkits and bootkits, which can compromise the security of the entire system. With Secure Boot enabled, every aspect of the boot process, from the boot loader to the kernel and kernel drivers, must be digitally signed by trusted publishers. This creates a robust shield against unauthorized modifications and ensures that the VM starts in a secure and trusted state. 2. Virtual Trusted Platform Module (vTPM): Your Secure Vault The vTPM is a virtualized version of a hardware Trusted Platform Module (TPM) 2.0 device. It serves as a dedicated secure vault for storing keys, certificates, and secrets. What sets vTPM apart is its ability to operate in a secure environment outside the reach of any VM, making it tamper-resistant and highly secure. One of the key functions of vTPM is attestation. It measures the entire boot chain of a VM, including UEFI, OS, system components, and drivers, to certify that the VM booted securely. This attestation mechanism is invaluable for verifying the integrity of VMs and ensuring that they have not been compromised. 3. Virtualization-based Security (VBS): Elevating Security Measures VBS is the final piece of the Trusted Launch puzzle. It leverages the hypervisor to create isolated, secure memory regions within the VM. VBS uses virtualization to enhance system security by creating an isolated, hypervisor-restricted, specialized subsystem. It provides protection against unauthorized access of credential, prevent malware from running on windows system and ensures only trusted code runs from bootloader onwards. Trusted Launch is more than a security feature—it's a commitment to ensuring your virtualized environments meet the highest standards of security and trust. By embracing Trusted Launch, you gain: Enhanced Security Posture: The combined power of Secure Boot, vTPM, and VBS elevates your security posture, making your virtualized environment more resilient against a multitude of cyber threats. Compliance and Regulatory Alignment: Trusted Launch aligns with stringent compliance requirements, ensuring your environment complies with industry standards and regulations. Peace of Mind: By utilizing Trusted Launch, you can trust that your VMs are booting securely, protecting against advanced attacks and unauthorized access. In the domain of Virtual Desktop Infrastructure (VDI), Trusted Launch emerges as a transformative force, especially in the context of Windows 11 enablement. As organizations gear up for the Windows 11 transition, Trusted Launch provides a pivotal security foundation. It not only ensures seamless compliance with regulatory requirements but also serves as a robust defense against persistent malware—a critical concern in VDI ecosystems. By enabling vTPM and integrating Secure Boot, Trusted Launch lays the groundwork for running Windows 11 securely within VDI environments, elevating the overall security posture and enabling a smooth and secure migration to this next-generation operating system. This is a significant leap towards a future where VDI operates on a trusted and resilient platform, setting the stage for a new era of secure virtualization. In a cyberspace ecosystem where threats continually evolve in complexity, Trusted Launch emerges as a beacon of hope, enhancing VM security to unprecedented levels. By seamlessly integrating Secure Boot, vTPM, and VBS, Trusted Launch fortifies VMs against advanced threats, providing a secure foundation for workloads. As Trusted Launch takes its place in Azure VMware Solution, the future of VM security appears brighter than ever, promising a secure and trusted boot process as the standard. Embrace Trusted Launch to secure tomorrow's virtual landscape today. Stay tuned for more updates as we continue to enhance and refine Trusted Launch to meet the evolving needs of secure cloud computing. Your security is our priority, and Trusted Launch is a testament to that commitment.
