Broadcom has announced changes are coming to its VMware licensing model on hyperscalers beginning in its new fiscal year on November 1, 2025. If you’re an Azure VMware Solution customer, here’s what you need to know about the new requirements and how they will affect your cloud deployments. What’s changing? Broadcom is changing its VMware licensing policies across all hyperscaler platforms to require customers to “bring your own” portable subscription for VMware Cloud Foundation (VCF). This means customers must purchase portable VCF subscriptions directly from Broadcom to use with cloud services in the future, including Azure VMware Solution. Azure VMware Solution already supports “bring your own” licensing model The good news is that Azure VMware Solution is ready for this change. The Azure VMware Solution VCF BYOL option is available in all 35 AVS regions worldwide, allowing customers to run AVS using their own VCF subscriptions. This BYOL solution is priced lower than AVS with bundled VCF subscription. No product changes to Azure VMware Solution These updates are about licensing only—there are no product changes to how Azure VMware Solution works. Microsoft will continue to deliver Azure VMware Solution as a fully managed VCF private cloud service on Azure. In practice, this means that Microsoft takes care of all infrastructure and VMware host level software management, patches and upgrades. You don’t need to worry about hardware maintenance or manual VMware host updates. Key dates and transition details Microsoft will stop selling Azure VMware Solution with VCF subscriptions included after October 15, 2025. After this date, new Azure VMware Solution node purchases will require you to provide a VCF subscription purchased from Broadcom. Microsoft will honor existing Reserved Instance commitments to Azure VMware Solution customers. If you purchase Azure VMware Solution Reserved Instances (RIs) on or before October 15, 2025, you can continue to use your Azure VMware Solution nodes without any licensing or product changes until your RI term ends. Azure VMware Solution with license included PayGo nodes can continue to operate without any licensing or product changes through October 31, 2026. Alternatively, customers can switch from Azure VMware Solution PayGo and purchase an Azure VMware Solution RI with license included by October 15, 2025. Helpful resources We’re committed to making this transition as smooth as possible for our customers and partners. Here are some helpful links with more details: How to use portable VCF subscriptions with Azure VMware Solution How to purchase an Azure VMware Solution RI Broadcom Blog announcing the VMware licensing change If you need to purchase VCF subscriptions and do not have a Broadcom contract, leverage one of the Broadcom channel partners here. We will be reaching out directly to current Azure VMware Solution customers with more details. If you have any questions, reach out to your Microsoft account representative so we can help you navigate this transition.
Azure VMWare (AVS) Cost Optimization Using Azure Migrate Tool
What is AVS? Azure VMware Solution provides private clouds that contain VMware vSphere clusters built from dedicated bare-metal Azure infrastructure. Azure VMware Solution is available in Azure Commercial and Azure Government. The minimum initial deployment is three hosts, with the option to add more hosts, up to a maximum of 16 hosts per cluster. All provisioned private clouds have VMware vCenter Server, VMware vSAN, VMware vSphere, and VMware NSX. As a result, you can migrate workloads from your on-premises environments, deploy new virtual machines (VMs), and consume Azure services from your private clouds. Learn More: https://learn.microsoft.com/en-us/azure/azure-vmware/introduction What is Azure Migrate Tool? Azure Migrate is a comprehensive service designed to help you plan and execute your migration to Azure. It provides a unified platform to discover, assess, and migrate your on-premises resources, including servers, databases, web apps, and virtual desktops, to Azure. The tool offers features like dependency analysis, cost estimation, and readiness assessments to ensure a smooth and efficient migration process. Learn More: https://learn.microsoft.com/en-us/azure/migrate/migrate-services-overview How Azure Migrate can be used to Discover and Assess AVS? Azure Migrate enables the discovery and assessment of Azure VMware Solution (AVS) environments by collecting inventory and performance data from on-premises VMware environments, either through direct integration with vCenter (via Appliance) or by importing data from tools like RVTools. Using Azure Migrate, organizations can analyze the compatibility of their VMware workloads for migration to AVS, assess costs, and evaluate performance requirements. The process involves creating an Azure Migrate project, discovering VMware VMs, and generating assessments that provide insights into resource utilization, right-sizing recommendations, and estimated costs in AVS. This streamlined approach helps plan and execute migrations effectively while ensuring workloads are optimized for the target AVS environment. Note: We will be narrating the RVtools Import method in this article. What Is RVTools? RVTools is a lightweight, free utility designed for VMware administrators to collect, analyze, and export detailed inventory and performance data from VMware vSphere environments. Developed by Rob de Veij, RVTools connects to vCenter or ESXi hosts using VMware's vSphere Management SDK to retrieve comprehensive information about the virtual infrastructure. Key Features of RVTools: Inventory Management: Provides detailed information about virtual machines (VMs), hosts, clusters, datastores, networks, and snapshots. Includes details like VM names, operating systems, IP addresses, resource allocations (CPU, memory, storage), and more. Performance Insights: Offers visibility into resource utilization, including CPU and memory usage, disk space, and VM states (e.g., powered on/off). Snapshot Analysis: Identifies unused or orphaned snapshots, helping to optimize storage and reduce overhead. Export to Excel: Allows users to export all collected data into an Excel spreadsheet (.xlsx) for analysis, reporting, and integration with tools like Azure Migrate. Health Checks: Identifies configuration issues, such as disconnected hosts, orphaned VMs, or outdated VMware Tools versions. User-Friendly Interface: Displays information in tabular form across multiple tabs, making it easy to navigate and analyze specific components of the VMware environment. Hand-on LAB Disclaimer: The data used for this LAB has no relationship with real world scenarios. This sample data is self-created by the author and purely for understanding the concept. To discover and assess your Azure VMware Solution (AVS) environment using an RVTools extract report in the Azure Migrate tool, follow these steps: Prerequisites RVTools Setup: Download and install RVTools from the RVTools Download Ensure connectivity to your vCenter server. Extract the data by running RVTools and saving the output as an Excel (.xlsx) file Permissions: You need at least the Contributor role on the Azure Migrate project. Ensure that you have appropriate permissions in your vCenter environment to collect inventory and performance data. File Requirements: The RVTools file must be saved in .xlsx format without renaming or modifying the tabs or column headers. Note: Sample Sheet: Please check the attachment included with this article. Note that this is not the complete format; some tabs and columns have been removed for simplicity. During the actual discovery and assessment process, please do not modify the tabs or columns. Procedure Step 1: Export Data from RVTools Follow the steps provided in official website to get RVTools Extract Sample Sheet: Please check the attachment included with this article. Note that this is not the complete format; some tabs and columns have been removed for simplicity. During the actual discovery and assessment process, please do not modify the tabs or columns. Step 2: Discover Log in to the Azure portal. Navigate to Azure Migrate and select your project or create new project. Under Migration goals, select Servers, databases and web apps. On Azure Migrate | Servers, databases and web apps page, under Assessment tools, select Discover and then select Using import. In Discover page, in File type, select VMware inventory (RVTools XLSX). In the Step 1: Import the file section, select the RVTools XLSX file and then select Import. Wait for some time to Import Once import completed check for Error Messages if any and rectify those and re upload, otherwise wait 10-15 minutes to reflect imported VMs in the discovery. Post discovery Reference Link: https://learn.microsoft.com/en-us/azure/migrate/vmware/tutorial-import-vmware-using-rvtools-xlsx?context=%2Fazure%2Fmigrate%2Fcontext%2Fvmware-context Step 3: Assess After the upload is complete, navigate to the Servers tab. Click on Assess -->Azure VMware Solution to assess the discovered machines. Edit assessment settings based on your requirements and Save Target region: Select the Azure region for the migration. Node Type: Specify the Azure VMware Solution series (e.g., AV36, AV36P). Pricing model: Select pay-as-you-go or reserved instance pricing. Discount: Specify any available discounts. Note: We will be explaining all the parameters in optimize session. As of now just review and leave parameters as it is. In Assess Servers, select Next. In Select servers to assess > Assessment name > specify a name for the assessment. In Select or create a group > select Create New and specify a group name. Select the appliance and select the servers you want to add to the group. Then select Next. In Review + create assessment, review the assessment details, and select Create Assessment to create the group and run the assessment. Step 4: Review the Assessment View an assessment In Windows, Linux and SQL Server > Azure Migrate: Discovery and assessment, select the number next to Azure VMware Solution. In Assessments, select an assessment to open it. As an example (estimations and costs, for example, only): Review the assessment summary. You can select Sizing assumptions to understand the assumptions that went in node sizing and resource utilization calculations. You can also edit the assessment properties or recalculate the assessment. Step 5: Optimize We have received a report without any optimization in our previous steps. Now we can follow below steps to optimize the cost and node count even further High level steps: Find limiting factor Find which component in settings are mapped for optimization depending on limiting factor Try to adjust the mapped component according to Scenario and Comfort Find Limiting factor: First understand which component (CPU, memory and storage) is deciding your ESXI Node count. This will be highlighted in the report The limiting factor shown in assessments could be CPU or memory or storage resources based on the utilization on nodes. It is the resource, which is limiting or determining the number of hosts/nodes required to accommodate the resources. For example, in an assessment if it was found that after migrating 8 VMware VMs to Azure VMware Solution, 50% of CPU resources will be utilized, 14% of memory is utilized and 18% of storage will be utilized on the 3 Av36 nodes and thus CPU is the limiting factor. Find which option in the setting can be used to optimize: This is depending on the limiting factor. For eg: If Limiting factor is CPU, which means you have high CPU requirement and CPU oversubscription can be used to optimize ESXI Node. Likewise, if storage is the limiting factor editing FTT, RAID or introducing External storage like ANF will help you to reduce Node count. Even reducing one node count will create a huge impact in dollar value. Let's understand how over commitment or over subscription works with simple example. Let's suppose I have two VMs with below specification Name CPU Memory Storage VM1 9 vCPU 200 GB 500 GB VM2 4 vCPU 200 GB 500 GB Total 13 vCPU 400 GB 1000 GB We have EXSI Node which has below capacity: vCPU 10 Memory 500 GB storage 1024 GB Now without optimization I need two ESXI node to accommodate 13 vCPU of total requirement. But let's suppose VM1 and VM2 doesn't consume entire capacity all the time. The total capacity usage at a time will not go beyond 10. then I can accommodate both VM in same ESXI node, Hence I can reduce my node count and cost. Which means it is possible to share resources among both VMs. Without optimization With optimization Parameters effecting Sizing and Pricing CPU Oversubscription Specifies the ratio of number of virtual cores tied to one physical core in the Azure VMware Solution node. The default value in the calculations is 4 vCPU:1 physical core in Azure VMware Solution. API users can set this value as an integer. Note that vCPU Oversubscription > 4:1 may impact workloads depending on their CPU usage. Memory overcommit factor Specifies the ratio of memory overcommit on the cluster. A value of 1 represents 100% memory use, 0.5, for example is 50%, and 2 would be using 200% of available memory. You can only add values from 0.5 to 10 up to one decimal place. Deduplication and compression factor Specifies the anticipated deduplication and compression factor for your workloads. Actual value can be obtained from on-premises vSAN or storage configurations. These vary by workload. A value of 3 would mean 3x so for 300GB disk only 100GB storage would be used. A value of 1 would mean no deduplication or compression. You can only add values from 1 to 10 up to one decimal place. FTT : How many device failure can be tolerated for a VM RAID : RAID stands for Redundant Arrays of Independent Disks Explains how data should be stored for redundancy Mirroring : Data will be duplicated as it is to another disk E.g.: To protect a 100 GB VM object by using RAID-1 (Mirroring) with an FTT of 1, you consume 200 GB. Erasure Coding : Erasure coding divides data into chunks and calculates parity information (redundant data) across multiple storage devices. This allows data reconstruction even if some chunks are lost, similar to RAID, but typically more space-efficient E.g.: to protect a 100 GB VM object by using RAID-5 (Erasure Coding) with an FTT of 1, you consume 133.33 GB. Comfort Factor: Azure Migrate considers a buffer (comfort factor) during assessment. This buffer is applied on top of server utilization data for VMs (CPU, memory and disk). The comfort factor accounts for issues such as seasonal usage, short performance history, and likely increases in future usage. For example, a 10-core VM with 20% utilization normally results in a 2-core VM. However, with a comfort factor of 2.0x, the result is a 4-core VM instead. AVS SKU Sizes Optimization Result In this example we got to know that CPU is my limiting factor hence I have adjusted CPU over subscription value from 4:1 to 8:1 Reduced node count from 6 (3 AV36P+3 AV64) to 5 AV36P Reduced Cost by 31% Note: Over-provisioning or over-committing can put your VMs at risk. However, in Azure Cloud, you can create alarms to warn you of unexpected demand increases and add new ESXi nodes on demand. This is the beauty of the cloud: if your resources are under-provisioned, you can scale up or down at any time. Running your resources in an optimized environment not only saves your budget but also allows you to allocate funds for more innovative ideas.Azure VMware Solution Broadcom VMSA-2025-0004 Remediation

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. VMware HCX is the mobility and migration software used by the Azure VMware Solution to connect remote VMware vSphere environments to the Azure VMware Solution. These remote VMware vSphere environments can be on-premises, co-location or cloud-based instances. Figure 1 – Azure VMware Solution with VMware HCX Service Mesh Broadcom has announced the end-of-life (EOL) for VMware HCX version 4.10.x, effective July 27, 2025. To proactively address this change and ensure continued support, Microsoft will begin upgrading all Azure VMware Solution customers using HCX Manager to HCX version 4.11.0. What Changes are introduced as part of HCX 4.11.0? With the release of HCX 4.11.0, Broadcom has made significant changes to the way HCX will be available for download and upgrades. Local Mode From HCX 4.11.0 onwards, HCX will only be available in local mode. This means that HCX systems running 4.11.0 or later will no longer receive upgrade notifications under the System updates section from Broadcom. Once HCX systems are upgraded to 4.11.0 using the offline bundle they will operate in Local mode only. Connection to VMware & Hybridity Depot. As of 4.11.0 activation key-based licensing has been deprecated. Activation keys in HCX 4.11.0 will stop working 450 days after the upgrade to HCX 4.11.0 takes place. HCX systems running versions prior to 4.11.0 that are currently using the activation keys will stop working when connect.hcx.vmware.com is decommissioned later this year. Please note, the following HCX functionality is deprecated in HCX 4.11.0 and will be removed in a future release. HCX is 4.11.0 will no longer be supported as of December 24 th , 2025. Customers should plan to migrate to an alternative solution at the earliest if they use any of the following features. HCX V2T Migration HCX WAN Optimization HCX Disaster Recovery vCenter Server Plug-in for HCX HCX UI – Tracking page in Migration interface What actions will customers need to take? To ensure smooth migration, customers will be required to upgrade any paired HCX connectors and service mesh appliances to HCX 4.11.0. Furthermore, customers may be required to execute a resync operation on each HCX service mesh on both the source and connector sides to ensure that no errors have occurred due to the upgrade. All Azure VMware Solution customers have now been notified of their preliminary scheduled upgrade date. Customers have the option to reschedule using the Azure VMware Solution portal but must complete this upgrade during US work hours before July 31. Microsoft will only upgrade the HCX Cloud Manager, the on-prem HCX manager and service mesh appliances will need to be upgraded by the customer. Once upgraded, customers will find previous and current versions of the HCX connector bundles, including HCX 4.11.0, in their vSAN datastore for cluster-1, under a folder named “AVS_Official_HCX_Connector_Binaries” The HCX 4.11.0 bundle should be used by customers to upgrade their on-prem HCX connector.

Firewall integration in Azure VMware Solution
2020 has been a year like no other. In just a few months' time, businesses have transformed and have accelerated their efforts to migrate to the cloud. Following our announcement of Azure VMware Solution (AVS) last year, we have been helping customers accelerate this move to cloud by providing an easy lift and shift migration. Albeit customers love the same operational experience for VMware workloads and use familiar VMware technologies like vCenter, NSX Manager, HCX etc. in AVS, they also want to leverage security integrations that they have invested in for years. Below are a few common questions that we get from customers around this topic. How can they use the same firewalls/tools that they have been using for years? How do they maintain the same security posture? How can they use the same firewall for both Azure and VMware workloads in AVS? In this blog series, we plan to discuss native security options, 3 rd party firewall integration with AVS along with a deep dive into configuration details. First in the series, this blog would summarize the security options available at your disposal. Let’s start with the built-in security capabilities that you can leverage in AVS. Built-in security/firewall with VMware NSX-T - VMware NSX-T is the default networking stack in AVS and it provides out-of-box security features that you can use to protect your workloads. Following are the capabilities that you can leverage. Distributed Firewall (DFW) -A stateful L3-L7 firewall that powers micro-segmentation and runs on your ESXi hosts in your AVS private cloud. DFW rules are enforced on the vNIC level of a VM workload and what that means is that the traffic is either allowed or dropped on the vNIC level based on the rule you defined. So, there is no more hair-pinning that traffic through a centralized or perimeter firewall. From a feature standpoint, it's rich and allows you to define security rules using network or application constructs. You could group the workloads using static (IPSet/NSX constructs like Segment etc.) or dynamic membership (VM tags, guest OS etc.). Even when you have a perimeter firewall, you should secure your East-West traffic. Gateway Firewall - A L4-L7 aware stateful North-South firewall that can be configured on NSX-T Tier-1 Gateway in AVS. It can also be used as an Inter-tenant or Inter-zone firewall i.e. filtering traffic between different tenants of your organization each with a dedicated Tier-1 Gateway. Azure Firewall - A managed, stateful firewall with built-in HA and SLA of 99.99% (when deployed in two or more availability zones). Customers can configure L3-L7 policies to filter traffic and take advantage of threat intelligence-based filtering to alert and deny traffic from/to known malicious IP addresses and domains. Please refer to the Azure firewall feature set here. If you are already using Azure firewall capabilities deployed in Azure Virtual WAN to protect resources in VNETs, you can connect the same virtual WAN hub over an express route connection to AVS and route internet traffic from AVS to Azure firewall. Let's switch gears and talk about the 3rd party firewall integration with Azure VMware Solution. There is a strong desire from customers to continue using the same firewall in AVS that they have been using in an on-premises datacenter. Based on the use-case, you could deploy a 3rd party firewall NVA in AVS private cloud or SDDC or leverage a firewall from Azure marketplace. Let's double click on both options. 3rd Party firewall deployed as NVA in AVS private cloud or SDDC -Before we discuss this integration, it's important to understand NSX-T deployment in AVS private cloud. When you create a private cloud in AVS, a default NSX-T Tier-0 Gateway configured in Active/Active mode and a default NSX-T Tier-1 Gateway configured in Active/Standby mode is deployed for you. Users can connect segments (logical switches) and provide East-West and North-South connectivity to the workloads connected on these segments. A 3rd party firewall NVA can be connected southbound to the default NSX-T Tier-1 gateway and this firewall can act as a North-South firewall or East-West firewall depending upon your use case. This integration is supported in following topologies. Option 1: Workload segments are directly connected to the firewall and the gateway on workloads is 3 rd party firewall. This topology restricts the users with numerous segments as the vNICs on the NVA becomes a limiting factor. Option 2: Workload segments are connected to an isolated Tier-1 and this Tier-1 gateway provides northbound connectivity to a 3 rd party firewall. This topology solves the problem of limited number of vNICs on NVA as you connect 100s of workload segments to an isolated Tier-1 which connects to the firewall NVA northbound. In this topology, isolated Tier-1s simulate security zones and the firewall can provide East-West filtering between security zones and North-South filtering for all traffic. We will discuss routing and other configuration details for these topologies in next part of this blog series. 3rd Party firewall deployed in Azure VNET – Customers can also deploy a 3 rd party firewall in Azure VNET and route traffic from AVS to this firewall via Azure Virtual WAN hub. To redirect internet traffic from AVS VMs to the firewall NVA, you need to connect AVS to an express route gateway in Azure virtual WAN and propagate a default route. Next, you configure a default route in Azure Virtual WAN hub to direct internet bound traffic to a NVA in spoke VNET. We will go through the configuration details in greater detail in upcoming blogs.
