Expanding the multicloud advantage: Database migration paths into Azure
Broaden your customer base and enhance your app’s exposure by bringing your AWS-based solution to Azure and listing it on Microsoft Marketplace. This guide walks you through how Azure database services compare to those on AWS—spotlighting differences in architecture, scalability, and feature sets—so you can make confident choices when replicating your app’s data layer to Azure. This post is part of a series on replicating apps from AWS to Azure. View all posts in this series For software development companies looking to expand or replicate their marketplace offerings from AWS to Microsoft Azure, one of the most critical steps is selecting the right Azure database services. While both AWS and Azure provide robust managed database options, their architecture, service availability, and design approaches vary. To deliver reliable performance, scale globally, and meet operational requirements, it’s essential to understand how Azure databases work—and how they compare to AWS—before you replicate your app. AWS to Azure database mapping When replicating your app from AWS to Azure, start by mapping your existing database services to the closest Azure equivalents. Both clouds offer relational, NoSQL, and analytics databases, but they differ in architecture, features, and integration points. Choosing the right Azure service helps keep your app performant, secure, and manageable—and aligns with Azure Marketplace requirements for an Azure-native deployment. AWS Service Azure Equivalent Recommended Use Cases & Key Differences Amazon RDS (MySQL/PostgreSQL) Azure Database for MySQL / PostgreSQL Fully managed relational DB with built-in HA, scaling, and security. Building Generative AI apps. Amazon RDS (SQL Server) Azure SQL Database or Azure SQL Managed Instance Use Azure SQL Database for modern apps; choose Managed Instance for near 100% compatibility with on-prem SQL Server. SQL Server on EC2 SQL Server on Azure VMs Best for lift-and-shift scenarios requiring full OS-level control. Amazon RDS (Oracle) Oracle Database@Azure Managed Oracle workloads with Azure integration. Amazon Aurora (PostgreSQL/MySQL) Azure Database for PostgreSQL (Flexible Server) or Azure Database for MySQL Similar managed experience for large workloads, consider Azure HorizonDB (public preview)—built on PostgreSQL to compete with Aurora & AlloyDB. Learn more. Amazon DynamoDB Azure Cosmos DB (NoSQL API) Global distribution, multi-model support, and guaranteed SLAs for latency and throughput. Amazon Keyspaces (Cassandra) Azure Managed Instance for Apache Cassandra Managed Cassandra with elastic scaling and Azure-native security. Cassandra on EC2 Azure Managed Instance for Apache Cassandra Same as above; ideal for lift-and-shift Cassandra clusters. Amazon DocumentDB MongoDB Atlas MongoDB on EC2 Azure DocumentDB Azure DocumentDB Azure DocumentDB Drop-in compatibility for MongoDB workloads with global replication and vCore-based pricing. Amazon Redshift Azure Synapse Analytics Enterprise analytics with integrated data lake and Power BI connectivity. Amazon ElastiCache (Redis) Azure Cache for Redis Low-latency caching with clustering and persistence options. Match your use case After mapping AWS services to Azure equivalents, the next step is selecting the right service for your workload. Start by considering the data model (relational, document, key-value), then factor in performance, consistency, and global reach. Building AI apps: Generative AI, vector search, advanced analytics. Relational workloads: Use Azure SQL Database, Azure SQL Managed Instance, or Azure Database for MySQL/PostgreSQL for transactional apps; enable zone redundancy for HA. Review schema compatibility, stored procedures, triggers, and extensions. Inventory all databases, tables, indexes, users, and dependencies before migration. Document any required refactoring for Azure. NoSQL workloads: Choose Azure Cosmos DB for globally distributed apps; select the API (No SQL, MongoDB, Cassandra) that matches your existing schema. Validate data: Model mapping and test migration in a sandbox environment to ensure data integrity and application connectivity. Analytics: For large-scale queries and BI integration, Azure Synapse Analytics offers MPP architecture and tight integration with Azure Data Lake. Inventory all analytics assets, ETL pipelines, and dependencies. Plan for migration using Azure Data Factory or Synapse pipelines. Test performance benchmarks and optimize query plans post-migration. Caching: Azure Cache for Redis accelerates app performance with in-memory data and clustering. Update application connection strings and drivers to use Azure endpoints. Implement retry logic and connection pooling for reliability. Validate cache warm-up and failover strategies. Hybrid scenarios: Combine Cosmos DB with Synapse Link (for Synapse as target) or Fabric Mirroring (for Fabric as target) for real-time analytics without ETL overhead. Assess network isolation, security, and compliance requirements. Deploy Private Endpoints and configure RBAC as needed. Document integration points and monitor hybrid data flows. Factor in security and compliance Encryption: Confirm default encryption meets compliance requirements; enable customer-managed keys (CMK) if needed. Enable Transparent Data Encryption (TDE) and review encryption for backups and in-transit data. Access control: Apply Azure RBAC and database-level roles for granular permissions. Audit user roles and permissions regularly to ensure least privilege. Network isolation: Use Private Endpoints within a virtual network to keep traffic off the public internet. Configure Network Security Groups (NSGs) and firewalls for additional protection. Identity integration: Prefer Managed Identities for secure access to databases. Integrate with Azure Active Directory for centralized identity management. Compliance checks: Verify certifications like GDPR, HIPAA, or industry-specific standards. Use Azure Policy and Compliance Manager to automate compliance validation Audit logging and threat detection: Enable audit logging and advanced threat detection with Microsoft Defender for all database services. Review logs and alerts regularly. Optimize for cost Compute tiers: Choose General Purpose for balanced workloads; Business Critical for low-latency and high IOPS. Review workload sizing and adjust tiers as needed for cost efficiency. Autoscaling: Enable autoscale for Cosmos DB and flexible servers to avoid overprovisioning. Monitor scaling events and set thresholds to control spend. Reserved capacity: Commit to 1–3 years for predictable workloads to unlock discounts. Evaluate usage patterns before committing to reservations. Serverless: Use serverless compute for workloads with completely ad hoc usage and low frequency of access. This eliminates the need for pre-provisioned resources and reduces costs for unpredictable workloads. Monitoring: Use Azure Cost Management and query performance insights to optimize spend. Set up budget alerts and analyze cost trends monthly. Include basic resource monitoring to detect adverse usage patterns early. Storage and backup costs: Review storage costs, backup retention policies, and configure lifecycle management for backups and archives. Data migration from AWS to Azure Migrating your data from AWS to Azure is a key step in replicating your app’s database layer for Azure Marketplace. The goal is a one-time transfer—after migration, your app runs fully on Azure. Azure Database Migration Service (DMS): Automates migration from RDS, Aurora, or on-prem to Azure Database, Azure SQL Managed Instance, Azure Database for MySQL/PostgreSQL, and SQL Server on Azure VM (for MySQL/PostgreSQL/SQL Server). Supports online and offline migrations; run pre-migration assessments and schema validation. Azure Data Factory: Orchestrates data movement from DynamoDB, Redshift, or S3 to Azure Cosmos DB or Synapse. Use mapping data flows for transformations and data cleansing. MongoDB migrations: Use the online migration utility designed for medium to large-scale migrations to Azure DocumentDB. Ensure schema compatibility and validate performance benchmarks before cutover. Cassandra migrations: Use Cassandra hybrid cluster or dual write proxy for Azure Managed Instance for Apache Cassandra. Validate schema compatibility and test migration in a sandbox environment. Offline transfers: For very large datasets, use Azure Data Box for secure physical migration. Plan logistics and security for device handling. Migration best practices: Schedule migration during a maintenance window, validate data integrity post-migration, and perform cutover only after successful data validation & verifications. Final readiness before marketplace listing Validate performance: Benchmark with real data and confirm chosen SKUs deliver required throughput and latency. Test application functionality under expected load and validate query performance for all critical scenarios. Lock down security: Ensure RBAC roles, Private Endpoints, and encryption meet compliance requirements. Review audit logs, enable threat detection, and verify access controls for all database and storage resources. Control costs: Verify autoscaling, reserved capacity, and cost alerts are active. Review storage and backup policies, and set up budget alerts for ongoing cost control. Enable monitoring: Set up dashboards for query performance, latency, and capacity. Configure alerts for failures, anomalies, and capacity thresholds. Monitor with Azure Monitor and Log Analytics for real-time operational insights. Documentation and support: Update migration runbooks, operational guides, troubleshooting documentation, and escalation contacts for post-migration support.

Broaden your customer base and enhance your app’s exposure by bringing your AWS-based solution to Azure and listing it on Microsoft Marketplace. This guide will walk you through how Azure storage services compare to those on AWS—spotlighting important differences in architecture, scalability, and feature sets—so you can make confident choices when replicating your app’s storage layer to Azure. This post is part of a series on replicating apps from AWS to Azure. View all posts in this series For software development companies looking to expand or replicate their marketplace offerings from AWS to Microsoft Azure, one of the most critical steps is selecting the right Azure storage services. While both AWS and Azure provide robust cloud storage options, their architecture, service availability, and design approaches vary. To deliver reliable performance, scale globally, and meet operational requirements, it’s essential to understand how Azure storage works—and how it compares to AWS—before you replicate your app. AWS to Azure storage mapping When replicating your app from AWS to Azure, start by mapping your existing storage services to the closest Azure equivalents. Both clouds offer robust object, file, and block storage, but they differ in architecture, features, and integration points. Choosing the right Azure service helps keep your app performant, secure, and manageable—and aligns with Microsoft Marketplace requirements for an Azure‑native deployment. AWS Service Azure Equivalent Recommended use cases & key differences Amazon S3 Azure Blob Storage (enable ADLS Gen2 for hierarchical namespace + POSIX ACLs) Object storage with strong consistency and tiering (Hot/Cool/Archive). Blob is part of an Azure Storage account; ADLS Gen2 unlocks data‑lake/analytics features. Amazon EFS Azure Files (SMB/NFS) General‑purpose shared file systems and lift‑and‑shift app shares. Azure Files supports full-featured SMB and fully POSIX compatible NFS shared filesystems on Linux. Amazon FSx for Windows File Server Azure Files (SMB) Windows workloads that need full NTFS semantics, ACLs, and directory integration. Use Premium for low‑latency shares. Amazon FSx for NetApp ONTAP Azure NetApp Files Enterprise file storage with predictable throughput/latency, multiprotocol (SMB/NFS), and advanced data management. Amazon EBS Azure Managed Disks (Premium SSD v2 or Ultra Disk for top performance) Low‑latency block storage for VMs/DBs with provisioned IOPS/MBps; choose Premium SSD v2/Ultra for tighter SLOs. Local NVMe on EKS Azure Container Storage Extreme performance for Kubernetes workloads with a familiar cloud-native developer experience Many EBS volumes (fleet scale) Azure Elastic SAN (VMs & AKS only) Pooled, large‑scale block for Azure VMs via iSCSI or AKS via Azure Container Storage; simplifies fleet provisioning and management. Tip: Some AWS services map to multiple Azure options. For example, EFS → Azure Files for straightforward SMB/NFS shares, or → Azure NetApp Files when you need stricter latency SLOs and multiprotocol at scale. Match your use case After mapping AWS services to Azure equivalents, the next step is selecting the right service for your workload. Start by considering the access pattern, object, file, or block, and then factor in performance, protocol, and scale. Object storage & analytics: Use Azure Blob Storage for unstructured data like images, logs, and backups. If you need hierarchical namespace and POSIX ACLs, enable Azure Data Lake Storage Gen2 on top of Blob. General file sharing / SMB apps: Choose Azure Files (SMB) for lift‑and‑shift scenarios and Windows workloads. Integrate with Entra ID for NTFS ACL parity, and select the Premium tier for low‑latency performance. NFS or multiprotocol file workloads: Start with Azure Files (NFS) for basic needs, or move to Azure NetApp Files for predictable throughput, multiprotocol support, and enterprise‑grade SLAs. High‑performance POSIX workloads: For HPC or analytics pipelines requiring massive throughput, use Azure Managed Lustre. Persistent storage for containers: Azure’s CSI drivers brings Kubernetes support for most Azure disk, files, and blob offerings. Azure Container Storage brings Kubernetes support for unique disk backends that are unsupported by the Azure Disks CSI driver, such as local NVMe. Block storage for VMs and databases: Use Azure Managed Disks for most scenarios, with Premium SSD v2 or Ultra Disk for provisioned IOPS and sub‑millisecond latency. For large fleets or shared performance pools, choose Azure Elastic SAN (VMs & AKS only). Quick tip: Start simple—Blob for object, Azure Files for SMB and NFS, Managed Disks for block—and scale up to NetApp Files, Elastic SAN, or Managed Lustre when performance or compliance demands it. Factor in security and compliance Encryption: Confirm default encryption meets your compliance requirements; enable customer‑managed keys (CMK) if needed. Access control: Apply Azure RBAC for role‑based permissions and ACLs for granular control at the container or file share level. Network isolation: Use Private Endpoints to keep traffic off the public internet and connect storage to your VNet. Identity integration: Prefer Managed Identities or SAS tokens over account keys for secure access. Compliance checks: Verify your chosen service meets certifications like GDPR, HIPAA, or industry‑specific standards. Optimize for cost Tiering: Use Hot, Cool, and Archive tiers in Blob Storage based on access frequency; apply Premium tiers only where low latency is critical. Lifecycle management: Automate data movement and deletion with lifecycle policies to avoid paying for stale data. Reserved capacity: Commit to 1–3 years of capacity for predictable workloads to unlock discounts. Right‑sizing: Choose the smallest disk, volume, or file share that meets your needs; scale up only when required. Monitoring: Set up cost alerts and review usage regularly to catch anomalies early; use Azure Cost Management for insights. Avoid hidden costs: Co‑locate compute and storage to prevent cross‑region egress charges. Data migration from AWS to Azure Migrating your data from AWS to Azure is a key step in replicating your app’s storage layer for Marketplace. The goal is a one‑time transfer—after migration, your app runs fully on Azure. Azure Storage Mover: A managed service that automates and orchestrates large‑scale data transfers from AWS S3, EFS, or on‑premises sources to Azure Blob Storage, Azure Files, or Azure NetApp Files. Ideal for bulk migrations with minimal downtime. AzCopy: A command‑line tool for fast, reliable copying of data from AWS S3 to Azure Blob Storage. Great for smaller datasets or scripted migrations. Azure Data Factory: Built‑in connectors to move data from AWS storage services to Azure, with options for scheduling and transformation. Azure Data Box: For very large datasets, provides a physical device to securely transfer data from AWS to Azure offline. Final readiness before marketplace listing Validate performance under load: Benchmark with real data and confirm your chosen SKUs deliver the IOPS and latency your app needs. Lock down security: Ensure RBAC roles are applied correctly, Private Endpoints are in place, and encryption meets compliance requirements.

Software development companies looking to migrate or replicate their applications from AWS to Azure need to understand how networking services in both platforms compare. While AWS and Azure offer similar networking capabilities, key differences in architecture and service offerings can impact the overall solution design. This article provides a comparative overview of the networking services in AWS and Azure, focusing on their unique features and distinctions. By understanding these differences, software companies can make more informed decisions when architecting cloud-native solutions on either platform. The article explores networking services at a high level, with a deeper dive into critical areas such as peering, routing, and elastic load balancing, where the platforms diverge most significantly. Networking services overview Virtual networks & subnets AWS uses Virtual Private Cloud (VPC) to create isolated networks, spanning all Availability Zones within a region. VPCs support public and private subnets, with VPC peering routing traffic between VPCs using private IPv4 or IPv6 addresses. Azure uses Virtual Networks (VNets), which provide isolation within a region and can span multiple Availability Zones. Azure's VNet peering connects multiple VNets, making them appear as one for connectivity purposes, routing traffic through Microsoft's private network. In AWS, subnets are confined to a specific AZ, while Azure subnets are not tied to a specific Availability Zone. This allows zonal resources to retain their private IPs even when placed in different zones within a region. Peering In AWS and Azure, transitive peering is not natively supported with standard VPC Peering connections. For example, VPC-A and VPC-C cannot communicate directly if they are only peered through VPC-B. To enable transitive routing, AWS offers Transit Gateway, which connects multiple VPCs, allowing traffic between VPC-A and VPC-C. Azure provides Azure Virtual WAN, a centralized hub-and-spoke architecture that simplifies global network connections with built-in transitive routing. VNet Peering uses static routing without BGP, while Azure Virtual WAN supports BGP for branch and ExpressRoute connectivity. Additionally, Azure Virtual WAN now supports BGP for inter-regional hub-to-hub routing, enabling dynamic route propagation across hubs, similar to AWS Transit Gateway peering across regions. See Azure Virtual WAN Pricing for cost considerations. Below is an example of Azure VNet Peering. Traffic management services AWS features Elastic Load Balancing (ELB) with Classic, Application, and Network Load Balancers. Azure has Azure Load Balancer, Azure Application Gateway, and Traffic Manager for load distribution and traffic management. Below is an application of Multi-region load balancing with Traffic Manager, Azure Firewall, and Application Gateway. AWS provides a suite of load balancers including Application Load Balancer (ALB) for Layer 7 traffic, Network Load Balancer (NLB) for high-performance Layer 4 workloads, and Classic Load Balancer (CLB) as a legacy option. These services integrate with a broad set of AWS offerings such as EC2, ECS, and Lambda, and are complemented by Global Accelerator for improving global traffic performance. Azure’s approach to traffic management is more modular. Azure Load Balancer handles Layer 4 traffic and comes in Basic and Standard SKUs for varying scale and resiliency. For Layer 7 scenarios, Azure offers Application Gateway with features like SSL termination and integrated WAF. Azure Front Door adds global Layer 7 load balancing with content acceleration, while Azure Traffic Manager enables DNS-based routing with geo-failover. These services are often used in combination to build resilient architectures, rather than mirroring AWS's load balancer offerings one-to-one. Content delivery and optimization Both AWS and Azure provide robust content delivery network (CDN) services to accelerate the global delivery of content, applications, and APIs. AWS offers CloudFront, a globally distributed CDN service that integrates seamlessly with AWS services, enabling the fast delivery of web content, videos, and APIs to end users. On the Azure side, Azure Front Door acts as a modern, high-performance CDN that also includes advanced load balancing, security features, and seamless integration with Azure services. While both services focus on enhancing global content delivery, Azure Front Door goes a step further by offering enhanced scalability and secure user experiences for content-heavy applications and APIs. Routing & gateways AWS uses route tables associated with subnets in a VPC to direct traffic within and outside the network—for example, toward Internet Gateways, NAT Gateways, or VPN/Transit Gateways. Azure uses User-Defined Routes (UDRs), which can be applied to subnets in a Virtual Network (VNet) and managed centrally via Azure Network Manager. The diagram shows a spoke network group of two VNets accessing a DNS service through a Firewall, where UDRs created by Network Manager make this routing possible. AWS relies on explicit route configurations and services like Transit Gateway for transitive routing across VPCs. Azure creates system routes by default and allows UDRs to customize traffic flow to resources like VPN Gateways, NAT Gateways, or Network Virtual Appliances (NVAs). For internet egress, Azure currently allows implicit SNAT via Standard Public IPs or Load Balancers without outbound rules, but this behavior will be retired on September 30, 2025. After that, outbound access will require explicit configuration using a NAT Gateway, Load Balancer outbound rule, or Azure Firewall. Both platforms provide VPN solutions for hybrid connectivity. AWS supports Site-to-Site VPN for linking on-premises data centers with VPCs, and Client VPN for individual users. Azure offers Site-to-Site (S2S) and Point-to-Site (P2S) VPNs, as well as VNet-to-VNet connections for secure inter-region communication. These VPN services work with their respective routing infrastructures to support secure hybrid and multi-region deployments. DNS services DNS plays a foundational role in service discovery and network communication across both AWS and Azure environments. AWS offers Route 53, a scalable DNS service that supports both public and private hosted zones. It provides features like health checks, weighted routing, and integration with AWS services for domain resolution. Azure delivers similar functionality through Azure DNS for public DNS hosting and Azure Private DNS for internal name resolution within VNets. Azure Private DNS zones can be linked to one or more VNets, enabling seamless name resolution without custom DNS servers. These services are often used alongside load balancers and private endpoints to ensure consistent, secure access to application components. Private connectivity Both AWS and Azure offer dedicated, high-performance private connections to enhance security and reduce latency for hybrid and multi-cloud architectures. AWS provides Direct Connect, which establishes a dedicated network connection from an on-premises data center to AWS. This ensures a more consistent network experience, particularly for workloads requiring low latency or high throughput. Similarly, Azure offers ExpressRoute, a private, dedicated connection from on-premises infrastructure to Azure, bypassing the public internet. These private links typically use technologies like MPLS or Ethernet, depending on the provider and partner, offering better performance and reliability than traditional VPNs. ExpressRoute connections are often used for mission-critical workloads, offering greater reliability, faster speeds, and enhanced security. Security groups and network ACLs Network-level security AWS offers Security Groups (stateful) and Network ACLs (stateless) for network-level security. Security Groups are applied at the instance level, while NACLs work at the subnet boundary, adding an extra layer of filtering. Azure uses Network Security Groups (NSGs) and Application Security Groups (ASGs), which are fully stateful and simplify rule management. NSGs can be applied at both the subnet and network interface level. While Azure lacks a direct equivalent to stateless NACLs, NSGs typically offer enough granularity for most use cases. Azure also offers more granular traffic control with User-Defined Routes (UDRs) and the option to disable "Allow forwarded traffic" in virtual network peering settings. This ensures tight control or blocking of traffic even between peered VNets. Web Application Firewall (WAF) When it comes to Web Application Firewalls, AWS and Azure differ in design and deployment models. AWS WAF can be deployed as a standalone resource and attached to services like CloudFront, API Gateway, or the Application Load Balancer. This offers a high degree of flexibility but may require more hands-on setup and configuration. In contrast, Azure WAF is designed to work in close integration with services such as Application Gateway and Azure Front Door. While not standalone, central WAF policies allow consistent policy reuse across deployments. From a performance perspective, AWS WAF is recognized for its robust application-layer controls and ability to handle high traffic loads efficiently. Azure WAF is often noted for its ease of setup and the depth of its reporting and diagnostics. Private access to PaaS services and Private Endpoints As cloud-native applications increasingly depend on managed services like storage, databases, and messaging queues, securely connecting to these services without exposing traffic to the public internet becomes a critical design consideration. In AWS, VPC Endpoints—available as Interface or Gateway types—allow private connectivity to supported services from within a VPC. Azure provides a similar capability through Private Link, leveraging Private endpoints enabling private access to Azure services such as Azure Storage, SQL Database, or even custom services behind a Load Balancer. Azure Private Link also supports private access to customer or partner services published via Azure Private Link Service. Both approaches improve security posture by keeping traffic on the cloud provider's internal backbone, reducing exposure to external threats. For software development companies building multi-tiered cloud-native applications, these features offer a straightforward way to lock down service-to-service communication without relying on public endpoints. Endpoint policy management In AWS, endpoint management is handled via VPC Endpoint Policies, API Gateway, and AWS PrivateLink. These resource-specific policies are applied to services like S3, DynamoDB, or API Gateway, offering granular control, but requiring more configuration. In contrast, Azure’s endpoint management is more centralized. Services like Azure Application Gateway, Front Door, and Private Endpoint are governed through Network Security Groups (NSGs), Azure Firewall, and WAF policies. Azure's centralized policy enforcement, particularly for Private Endpoints, provides simplified access control and reduces the need for per-service configurations. AWS offers granular control at the cost of additional configuration complexity. Service mesh for Microservices For applications composed of many microservices, managing east-west traffic, enforcing security policies, and gaining observability into service communication can become complex. A service mesh addresses these challenges by abstracting service-to-service communication into a dedicated infrastructure layer. AWS offers App Mesh, which integrates with ECS, EKS, and Fargate, providing features like traffic shifting, retries, circuit breaking, and mTLS encryption. Azure supports service meshes primarily through open-source solutions like Istio and Linkerd, facilitated by managed integrations via the AKs service mesh add-on, simplifying operations on AKS. Additionally, Azure provides Dapr, which complements service mesh by offering higher-level application concerns such as state management, pub/sub messaging and simplified service invocation. For cloud-native software development companies adopting Kubernetes or containerized architectures, a service mesh brings consistency, security, and fine-grained control to internal traffic management. Monitoring and observability Azure Network Watcher provides tools for monitoring, diagnosing, and logging network performance across IaaS resources in Azure. Key features include topology visualization, connection monitoring, and various diagnostic tools like IP flow verification, NSG diagnostics, and packet capture. Additionally, Traffic Analytics provides insights into network traffic patterns. These tools support both hybrid and fully cloud-based network infrastructures, enabling efficient troubleshooting and performance optimization. On the AWS side, VPC Flow Logs and Reachability Analyzer provide comparable visibility and connectivity diagnostics.

Co-sell with 35,000 Microsoft sellers: Sell even more with collaborative sales through the marketplace, Expand to new markets with recurring revenue: Scale through 500,000 Microsoft partners, who can sell on your behalf or sell jointly to customers. This article walks you through the essentials of publishing and selling through the marketplace, including offer types, billing and pricing models, tools, incentives, and financial programs that can accelerate your success. 2. Selecting the right marketplace offer type When publishing to the marketplace, choosing the right offer type is key. Each type supports different ways customers use and deploy your solution. Common Offer Types and What They’re Best For Software as a Service (SaaS) Best for apps deployed on your Azure infrastructure that customers access through subscriptions. For customers who want a turnkey ready-to-use, hosted solution with minimal set-up. Azure Virtual Machine (VM) Best for software that runs on a pre-configured virtual machine. Similar to Amazon Machine Image (AMI) offers. For customers who want full control over a virtual machine running your software. Azure Container Ideal for containerized apps that customers deploy and run themselves like Amazon Elastic Container Service (ECS) or Elastic Kubernetes Service (EKS). For customers who want to run your app in their own container environment. Azure Application Used to deploy multiple Azure resources like VMs, storage, or networking. This is ideal for customers who want packaged deployments that automate setup in the customer’s environment. Azure also supports other offer types. See the full list at App Advisor – Offer Types. 3. How marketplace billing and pricing work A key advantage of publishing through the marketplace is the seamless integration with Azure’s billing system, which simplifies procurement for customers and streamlines revenue collection for software development companies. Integrated Azure billing When customers purchase through the marketplace, charges are seamlessly applied to their existing Azure account, eliminating separate invoicing and procurement workflows. Purchases can count toward Azure Consumption Commitment, enhancing appeal for enterprise buyers, while customers benefit from consolidated billing and simplified expense tracking. Publisher earnings Microsoft manages billing and collection. After deducting a standard transaction fee, earnings are disbursed on a regular schedule—reducing overhead and ensuring predictable cash flow. Pricing models The marketplace supports a variety of pricing models to align with your business model and customer expectations: Flat-rate: A fixed monthly or annual fee for access to your solution. Per user pricing: Charges based on the number of users accessing the solution. Usage-based (metered): Charges based on actual usage metrics (e.g., API calls, compute hours). After choosing your pricing model, you can configure multiple tiered plans (SKUs) for different service levels or feature sets at varying price. Renewing a private offer with an existing paid customer—whether the original deal was through the marketplace or not— reduces your transaction fee by 50% for the entire renewal term. How to grow sales with negotiated deals For many enterprise customers, closing deals means negotiating pricing and terms. Most co-sell deals also happen through negotiated terms. If co-selling with Microsoft sellers is a path you want to pursue, make sure you learn about these options. Private offers: Depending on the plan you have selected, you can create personalized pricing and terms for specific customers that are only visible to them. Offers can include custom billing schedules, discounts, and contract durations. Multiparty private offers: If you sell through channel partners or need to for a specific deal, then you can use multiparty private offers (MPO) to offer negotiated terms and pricing. MPO is currently available in the United States, United Kingdom and Canada, with support for more geographies coming soon. The Private Offers API allows you to programmatically create and manage custom deals with enterprise customers. These capabilities allow you to maintain pricing flexibility while benefiting from the streamlined procurement and billing experience of the marketplace. Learn more on your options for negotiated deals through marketplace. Transactable professional services In addition to software, you can also list professional services (e.g., onboarding, training, consulting) as transactable items. This allows customers to purchase both your product and value-added services through a single, unified channel—further increasing your Azure Consumption Commitment alignment and revenue potential. These offers are currently not discoverable via storefront search and must be shared via direct link with customers. Transactable services are supported in select markets and must follow specific publishing guidelines.

Private offers overview - Marketplace customer documentation | Microsoft Learn Marketplace FAQs – Microsoft Tech CommunityExpanding the multicloud advantage: Picking the right Azure regions for AWS developers
This post is part of a series on replicating apps from AWS to Azure. View all posts in this series. As a software development company, expanding or replicating your Marketplace offer from AWS to Microsoft Azure, one of the most foundational steps is selecting the right Azure region. While AWS and Azure both offer extensive global infrastructure, the architecture, service availability, and underlying design philosophies differ. For software companies aiming to deliver consistent performance, scale globally, and meet operational expectations, understanding how Azure regions work—and how they compare to AWS—is essential. Choosing the right Azure region is a critical step in successfully replicating your AWS-based app. Understanding how Azure regions differ from AWS—across availability, service coverage, and compliance—can help you make smarter decisions that improve performance, reduce latency, and meet customer expectations. This article will guide you through key regional considerations to help you plan your multicloud expansion with confidence. You can also join ISV Success to get access to over $126K USD in cloud credits, AI services, developer tools, and 1:1 technical consults to help you replicate your app and publish to Azure Marketplace. To replicate your app faster get cloud-ready reference code to replicate AWS apps to Azure. This guide breaks down everything software development companies need to know to make informed region decisions based on your business and operational requirements like availability, reliability, resiliency, performance, security, compliance, and cost. Key factors for region selection 1. Understanding the Region and Availability Zone Models Before you map your AWS architecture to Azure, it's important to understand how the two platforms structure their global infrastructure. Both AWS and Azure use regions and Availability Zones (AZs) to deliver high availability and resilience. AWS regions typically include 3–6 AZs—physically separated data centers that support fault-tolerant architectures. Azure also offers multiple AZs in supported regions (usually three or more) and introduces a unique concept: region pairs—predefined, geographically aligned region combinations designed for disaster recovery and sequential update rollout. While not all Azure regions currently include AZs, Azure’s expansive global footprint—more regions than any other cloud provider—gives software companies exceptional flexibility to deploy close to customers, meet data residency requirements, and scale with confidence. As you plan your region strategy, it’s also essential to consider Azure's broad geographic coverage. Azure offers an extensive and diverse network of regions, including emerging markets, such as South Africa, the Middle East, and parts of Eastern Europe. This expanded reach can help software companies unlock new opportunities in underserved markets. Expanded Market Access: Azure's unique regional presence enables software companies to serve new customer segments and comply with local data regulations. Geographic Flexibility: With over 60 regions worldwide, you can design a global presence tailored to your users' needs. Just be sure to check the Azure Products by Region to confirm that your required services are available in each region you’re considering. 2. Availability Zones and high availability Software companies coming from AWS are accustomed to architecting for resiliency using multi-AZ deployments, which distribute workloads across isolated data centers within a region to avoid a single point of failure. Azure supports a similar model—but with important considerations. Check AZ Support: about half of Azure regions support availability zones. You can verify this on Microsoft’s Azure region availability page. Region Pairs: If your target region doesn’t support AZs, leverage region pairs to implement cross-region redundancy. Example: If you’re used to deploying across us-west-1 and us-west-2 in AWS for failover, you might consider Azure’s West US and West Central US, which are region pairs designed for this purpose. 3. Service availability by region Azure continuously expands its global reach, with advanced and preview services becoming available in select regions first-providing early access and ensuring a phased, reliable rollout across location. Verify service coverage: Use the Azure Products by Region tool to ensure your required services—like Azure Container Apps, Cosmos DB, or Azure OpenAI—are supported in your target region. Verify SKU coverage: When deploying services such as AKS (Azure Kubernetes Service), it’s vital to confirm not only the availability of the service in your chosen region but also the support for the specific VM SKU required for the AKS node pool. When planning your Azure deployment, it’s crucial not only to verify the availability of core services in your chosen region but also to ensure that all required features, SKUs, and dependent services—such as networking, identity, storage, and monitoring—are supported. This comprehensive approach prevents unexpected issues during provisioning and guarantees the full operational functionality of your solution. 4. Disaster recovery and resilience Azure offers parallel capabilities to cross-region replication available in AWS but implements differently. Region Pairs: Azure automatically geo-replicates platform services like Azure Storage and Azure SQL between paired regions. Manual Replication: Use Azure Site Recovery for infrastructure-level disaster recovery between any two regions. Zonal and Regional Redundancy: Zonal and regional redundancy are available to meet your fault tolerance requirements—Zonal redundancy enables automatic failover across zones for services with multi AZ enabled in a single region, protecting against localized datacenter failures while maintaining low-latency access. Regional resiliency provides resiliency against full region outage by replicating services across geographically separate region—ideal for disaster recovery scenarios. Multi-AZ failover protects against localized datacenter issues within a region, offering high availability with low latency. Multi-region failover safeguards against full region outages by replicating services across geographically separate Azure regions. 5. Network latency and performance optimization Latency isn't just about user experience—it's also critical for communication between services and data centers. Optimizing network design ensures your applications perform reliably under real-world conditions. Virtual Network Peering: Azure's VNet peering (similar to AWS VPC Peering) enables private, low-latency communication between virtual networks, both within a region and across regions, without traffic traversing the public internet. Azure ExpressRoute: For scenarios requiring consistent, ultra-low latency between on-premises infrastructure and Azure, ExpressRoute provides a dedicated private connection. This is Azure’s counterpart to AWS Direct Connect. Private Endpoint: Allow access to Azure services via Private Link, over a private IP within your VNet—bypassing the public internet. This reduces exposure to internet congestion and can improve network latency, while also enhancing security. Content Delivery: To speed up access to static assets and media globally, Azure CDN offers a solution comparable to AWS CloudFront, using distributed edge locations to reduce load times. For latency testing, use Azure Speed Test or Network Performance Monitor to evaluate performance across Azure regions. This is similar to how AWS professionals might use CloudWatch or the AWS Network Performance Dashboard to test latency and identify the best-performing regions for their user base. Additional tools are available like Network Watcher and Flow Logs. Latency is critical for real-time applications (e.g., video conferencing, online gaming), financial services and IoT and edge computing solutions. It’s less critical with batch processing, archival and backup storage and internal business applications and admin system. 6. Compliance and data residency Now let’s talk about compliance—something every software company must consider, even if it’s not their primary driver. Azure provides robust options for regulated industries: Examples of Sovereign Clouds: Azure Government: for U.S. federal and state agencies Azure China: operated independently by 21Vianet Azure Germany: for data residency and sovereignty in the EU Azure Australia: supports public sector and regulated industries with regional compliance and data residency Compliance Certifications: Azure supports over 100 compliance offerings, including GDPR, HIPAA, FedRAMP, ISO 27001, and more. Best Practices: Match your AWS GovCloud or other regulated deployment to a comparable Azure region (e.g., Azure Government). Confirm that your selected region supports required certifications by referencing Microsoft’s Compliance Documentation. 7. Cost differences by region Azure pricing varies by region, just like with AWS. Factors include local energy costs, demand, and capacity. Here is a high-level overview of how cost may vary by region Pricing - Bandwidth | Microsoft Azure Azure Pricing Calculator: Use it to compare compute, storage, and bandwidth pricing between regions. TCO Analysis: A slightly more expensive region may be worth the cost if it offers better performance, compliance, or redundancy options. 8. Planning for future growth Your choice of region affects more than just your launch—it sets the stage for growth. Scalability: Choose regions with broad service availability and sufficient capacity. Azure region capacity isn't infinite—some regions may experience temporary resource constraints for specific VM sizes or services due to high demand. Selecting a region with strong infrastructure investment and consistent capacity growth helps ensure your workloads can scale reliably over time. Expansion Strategy: Plan for multi-region deployments as your user base grows. Example of Mapping AWS Regions to Azure: Common Alignments AWS Region Closest Azure Region US East (N. Virginia) East US US West (N. California) West US Europe (Ireland) West Europe Asia Pacific (Singapore) Southeast Asia Asia Pacific (Tokyo) Japan East Here is the list of comprehensive Azure Regions. 9.

This post is part of a series on replicating apps from AWS to Azure. View all posts in this series. As a software development company, expanding your marketplace presence beyond AWS Marketplace to include Azure Marketplace can open new doors to grow your customer base. Azure’s broad ecosystem and diverse user base offer a dynamic platform to enhance your application’s reach and potential. To ensure a smooth app replication, start by understanding the key differences between AWS IAM and Microsoft Entra ID. A clear grasp of these distinctions will help you transition identity management effectively while optimizing security and performance on Azure. This guide will highlight these differences, map comparable services, and provide actionable steps for a seamless IAM replication. You can also join ISV Success to get access to over $126K USD in cloud credits, AI services, developer tools, and 1:1 technical consults to help you replicate your app and publish to Azure Marketplace. This article addresses Identity and Access Management (IAM) and select Identity Services: Amazon Cognito vs. Microsoft Entra ID. Identity and Access management (IAM) Identity and Access Management (IAM) is essential for securing and managing who can access resources, under what conditions, and with what specific permissions. AWS and Azure both offer robust IAM solutions to manage identities, roles, and policies, but they differ significantly in architecture, integration capabilities, and ease of use, particularly for software companies building SaaS solutions migrating from AWS to Azure. Users, Groups, and Roles AWS IAM creates users within an AWS account, grouping them into IAM User Groups, while Azure IAM manages users as directory objects in Microsoft Entra ID, assigning permissions via Azure RBAC. Both support MFA and identity federation through SAML, Azure enforcing Conditional Access based on location, device state, and user risk. AWS IAM grants permissions using JSON-based policies, allowing roles to be assumed by users, AWS services, or external identities without permanent credentials. Azure IAM assigns permissions via RBAC to users, groups, and service principals, offering predefined and customizable roles. Azure supports federated identity for hybrid environments, while Azure integrates with on-premises Microsoft Entra ID. Permissions and Policies AWS IAM employs JSON-based policies for granular permissions across AWS services. Policies can be identity-based, directly attached to users or roles, or resource-based, applied directly to resources such as S3 buckets or DynamoDB tables. AWS supports temporary credentials via roles, which can be assumed by users, AWS services, or external federated identities. Azure RBAC leverages predefined roles (e.g., Global Administrator, Contributor, Reader) or custom roles, offering clear hierarchical permissions management across resource, resource group, subscription, or management group levels. AWS also allows conditional permissions through advanced policy conditions (e.g., IP address, MFA status, tags). Azure IAM employs Conditional Access Policies, adjusting access based on location, device state, and user risk. AWS IAM grants access only when explicitly allowed, whereas Azure IAM evaluates role assignments and conditions before permitting actions. For multi-account and cross-tenant access, AWS IAM enables secure cross-account roles, while Azure IAM supports External Identities for inter-tenant collaboration. AWS IAM delegates administrative rights using roles and policies, whereas Azure IAM assigns administrative roles within organizations for delegated management. AWS IAM enables controlled, temporary access to S3 objects using pre-signed URLs, which grant time-limited access to specific resources without modifying IAM policies. These URLs are often used for secure file sharing and API integrations. In Azure, a similar concept exists with Shared Access Signatures (SAS) Keys, which provide scoped and time-limited access to Azure Storage resources like Blob Storage, Table Storage, and Queues. Unlike pre-signed URLs, SAS keys allow granular control over permissions, such as read, write, delete, or list operations, making them more flexible for temporary access Integration with External Identities Both platforms provide Single Sign-On (SSO). AWS IAM uses AWS SSO. Microsoft Entra ID also supports SSO with SAML, OAuth, and OIDC. For federated identities, AWS IAM allows external users to assume roles, while Microsoft Entra ID assigns roles based on its access model. Hybrid environments are supported through on-premises directory integration. AWS IAM connects to Active Directory via AWS Directory Service, while Microsoft Entra ID integrates with on-prem AD using Microsoft Entra ID Connect, enabling hybrid identity management and SSO for cloud and on-prem resources. Both support automated user provisioning: AWS IAM utilizes AWS SSO and federation services, while Microsoft Entra ID supports SCIM 2.0 for third-party applications and syncs on-prem AD via Entra ID Connect. AWS IAM enables ECS, EKS, and Lambda workloads to pull container images from Amazon Elastic Container Registry (ECR) using IAM roles. These roles grant temporary permissions to fetch container images without requiring long-term credentials. In Azure, Azure Container Registry (ACR) authentication is managed through Service Principals and Managed Identities. Instead of IAM roles, Azure applications authenticate using Entra ID, allowing containers to securely pull images from ACR without embedding credentials. Access Control Models AWS IAM uses a policy-based access model, where permissions are defined in JSON policies attached to users, groups, or roles. In contrast, Azure separate's identity management via Microsoft Entra ID from access management via Azure RBAC, which assigns roles to users, groups, service principals, or managed identities to control access to Azure resources. Both provide fine-grained access control. AWS IAM sets permissions at the resource level (e.g., EC2, S3), while Azure uses Azure RBAC to assign Microsoft Entra ID identities roles that apply hierarchically at the resource, subscription, or management group levels. Both follow a default "deny" model, granting access only when explicitly allowed. For multi-account and multi-tenant support, AWS IAM enables cross-account roles. Microsoft Entra organizations can use External ID cross-tenant access settings to manage collaboration with other Microsoft Entra organizations and Microsoft Azure clouds through B2B collaboration and B2B direct connect. Delegation is managed through IAM roles in AWS and RBAC role assignments in Azure. Conditional access is supported—AWS uses policy-based conditions (e.g., time-based, IP restrictions), while Microsoft Entra ID relies on Conditional Access Policies (e.g., location, device health, risk level). AWS allows cross-account policy sharing, while Microsoft Entra ID enables role-based delegation at different organizational levels. Both support cross-service permissions, AWS IAM policies can define access across multiple AWS services, while Azure uses Azure RBAC to assign Microsoft Entra ID identities permissions across Azure services such as Blob Storage, SQL Database, and Key Vault. For workload authentication, AWS IAM roles provide temporary credentials for EC2, Lambda, and ECS, eliminating hardcoded secrets. In Azure, Microsoft Entra ID enables Managed Identities, allowing applications running on Azure services to authenticate securely to other Azure resources without managing credentials. Additionally, Microsoft Entra Workload Identities allow Kubernetes workloads—especially on AKS—to authenticate using Entra ID via OpenID Connect (OIDC), streamlining access to Azure services in containerized and multi-tenant environments. In AWS, containerized workloads such as ECS, EKS, and Lambda use IAM roles to securely authenticate and pull images from Amazon ECR, avoiding hardcoded credentials. In Azure, containerized applications authenticate to Azure Container Registry (ACR) using Microsoft Entra ID identities—either Managed Identities or Service Principals. Permissions such as AcrPull are granted via Azure RBAC, enabling secure image access. Azure’s model supports cross-tenant authentication, making it particularly useful for ISVs with multi-tenant containerized SaaS deployments. Cross-account storage access in AWS uses IAM roles and bucket policies for Amazon S3, allowing external AWS accounts to securely share data. In Azure, Microsoft Entra ID B2B and RBAC assignments. This model avoids the need to share credentials or manage access via SAS tokens, streamlining collaborations in multi-tenant environments. Audit and Monitoring AWS IAM and Microsoft Entra ID both provide robust audit logging and monitoring. AWS CloudTrail logs IAM and AWS API calls for 90 days by default, with extended retention via CloudTrail Lake or Amazon S3. Microsoft Entra ID logs sign-ins, including failed attempts, retaining data for 7 days in the free tier and up to 30 to 90 days in Premium tiers. For longer retention, Log Analytics or Sentinel should be used. For real-time monitoring, AWS CloudWatch tracks IAM activities like logins and policy changes, while Microsoft Entra ID Premium does so via Azure AD Identity Protection. AWS uses CloudWatch Alarms for alerts on permission changes, whereas Microsoft Entra ID alerts on suspicious sign-ins and risky users. AWS GuardDuty detects IAM threats like unusual API calls or credential misuse, while Microsoft Entra ID’s Identity Protection identifies risky sign-ins (Premium P2 required). AWS Security Hub aggregates findings from CloudTrail and GuardDuty, while Microsoft Entra ID integrates with Azure Sentinel for advanced security analytics. For IAM configuration tracking, AWS Config monitors policies and permissions, while Microsoft Entra ID’s Audit Log track's role, group, and user changes. AWS Artifact provides downloadable compliance reports. Microsoft Purview Compliance Manager enables customers to assess and manage their compliance across services like Entra ID and Azure using built-in control assessments. AWS CloudTrail logs IAM activity across AWS Organizations, and Microsoft Entra ID Premium supports cross-tenant access monitoring. Azure Lighthouse enables cross-tenant management for service providers, integrating with Microsoft Entra ID for delegated access without guest accounts. It applies RBAC across tenants and manages shared resources like Azure Blob Storage and virtual machines, streamlining ISV operations in marketplace scenarios. Pricing AWS IAM and Microsoft Entra ID provide core IAM services for free, with advanced features available in paid tiers. Both platforms support unlimited users for basic IAM functions, with AWS offering free user, role, and policy creation, while Microsoft Entra ID allows up to 500,000 objects (users/groups) at no cost. Additional users can be added for free, though advanced features require a paid plan. MFA is free on both platforms, but Microsoft Entra ID includes advanced MFA options in Premium tiers. AWS does not have risk based Conditional Access for free. Microsoft Entra ID includes it in Premium P1/P2 tiers (starting at $6 per user/month) Custom policies for fine-grained access control are free in AWS and Azure. Identity federation is free in AWS IAM, while Microsoft Entra ID requires a Premium P1/P2 plan. Microsoft Entra ID includes Self-Service Password Reset (SSPR) in Premium P1/P2, whereas AWS IAM does not offer it for free. Both platforms support RBAC at no extra cost. Directory synchronization is available via Microsoft Entra ID Premium P1/P2. AWS Directory Service is a paid managed AD service, not part of IAM. AWS IAM doesn’t have a direct “guest user” concept; instead, you configure federated access or cross-account roles, but Microsoft Entra ID requires a Premium tier for Azure AD External Identities. Full API and CLI access for user, policy, and role management is free on both platforms. Advanced security monitoring is available through AWS GuardDuty and Security Hub at an extra cost. Microsoft Entra ID provides advanced security monitoring, such as risk-based conditional access, within Premium P1/P2 tiers. Both platforms offer free support for service principals, enabling secure application access and role assignments. Amazon Cognito vs. Microsoft Entra ID Amazon Cognito provides identity and access management for applications in AWS, while Azure offers this through Microsoft Entra ID, centralizing IAM tools for ISVs. Both differ in authentication, integration, and target audiences. User management Amazon Cognito uses User Pools for authentication and Identity Pools for federated identities. Microsoft Entra ID serves as a central identity directory for Azure, Microsoft 365, and third-party apps, integrating with on-prem AD. Authentication methods Both support password-based login, MFA, passwordless authentication, and social sign-in. Amazon Cognito can be extended to support passwordless authentication with magic links, OTPs, and FIDO2 using AWS Lambda. Microsoft Entra ID supports native passwordless options like FIDO2, Windows Hello, and OTPs, plus risk-based conditional authentication. Identity Federation & SSO Amazon Cognito supports SAML, OAuth 2.0, and OIDC. Microsoft Entra ID offers enterprise SSO with SAML, OAuth, and WS-Federation, plus cross-tenant federation via Entra ID B2B. Access Control & Security Policies AWS relies on AWS IAM and custom logic for built-in RBAC or Attribute Based Access Control (ABAC). Microsoft Entra ID includes RBAC, ABAC, and Conditional Access Policies for granular security control. Self-Service & User Management Amazon Cognito allows self-registration and password resets, with workflow customization via AWS Lambda. Microsoft Entra ID offers SSPR, access reviews, and an enterprise portal for account management. Security & Compliance Amazon Cognito provides monitoring via AWS CloudTrail and GuardDuty, compliant with HIPAA, GDPR, and ISO 27001. Microsoft Entra ID integrates with Microsoft Defender for Identity for threat detection, with compliance for HIPAA, GDPR, ISO 27001, and FedRAMP, plus risk-based authentication in premium tiers. Migration best practices tips When migrating IAM from AWS to Azure, organizations should: Assess existing AWS IAM policies and roles, mapping them carefully to Azure RBAC roles. Leverage Microsoft Entra Connect for seamless integration with existing on-premises Active Directory environments.

Overview of cloud security models When moving your app from AWS Marketplace to Azure Marketplace, it's important to understand the key differences between AWS and Azure security models to ensure a smooth transition. Here are the main points you should keep in mind: AWS: In AWS’s shared responsibility model, AWS handles infrastructure security (like physical security and network controls), while you are responsible for securing your applications, data, and access controls. This includes managing network security, identity and access management (IAM), and data encryption. AWS uses services like Amazon GuardDuty and Amazon Inspector for threat protection and threat detection and vulnerability monitoring. Azure: Azure’s shared responsibility model focuses on compliance and regulatory requirements. It offers integrated services to secure data, applications, and infrastructure, simplifying compliance. Azure natively integrates with third-party security tools like Palo Alto Networks, Check Point, CrowdStrike and McAfee via services like Microsoft Defender for Cloud and Microsoft Sentinel for centralized security and threat detection. Microsoft Entra ID works with third-party identity providers such as Okta and Ping Identity for flexible authentication and access management without being locked into a single vendor. The Azure Marketplace also offers pre-configured security solutions, simplifying deployment and integration of security tools while maintaining flexibility. Understanding these differences can significantly ease the process and enhance the security of your cloud solutions, setting you up for success on both platforms. Figure 1https://learn.microsoft.com/en-us/azure/architecture/guide/security/security-start-here Identity and Access Management (IAM) IAM ensures that only authorized users and services can access cloud resources. AWS and Azure differ in how they manage user identities and permissions. Understanding these differences will help you map your AWS app to Azure by leveraging Azure’s IAM services. AWS: AWS uses IAM to centrally manage user identities and access permissions, with roles and policies defined in JSON for granular control. It also offers AWS Cognito for user identity management in custom applications and AWS SSO to simplify authentication across AWS accounts. While AWS IAM provides flexibility, it requires more manual configuration for complex use cases. Azure: Azure uses Microsoft Entra ID (formerly Azure AD), a cloud-based identity and access management service that provides more integrated security, especially for enterprise environments. It supports Role-Based Access Control (RBAC), which simplifies permission management by assigning predefined roles to users or groups, and integrates seamlessly with Microsoft products like Office 365, Microsoft Entra ID Connect, and third-party applications. It also offers advanced features like multi-factor authentication (MFA) and conditional access policies for context-based authentication. For ISVs migrating from AWS to Azure, Entra ID offers a more unified, scalable solution, particularly for hybrid environments and organizations with existing Microsoft infrastructure.

AWS vs. Azure AWS and Azure are the top cloud platforms with diverse services for developers and businesses. Below, we will highlight key areas where AWS and Azure differ—and how to leverage Azure services—when moving your Marketplace offer from AWS to Azure Marketplace. Azure Marketplace capabilities In Azure, ISVs can leverage metered billing to charge customers based on actual usage, similar to AWS's pay-as-you-go model. This flexible pricing model is ideal for SaaS solutions. Partner Center offers tools for setting pricing models, tracking usage, and adjusting billing. It also provides anomaly detection to help partners identify unexpected usage and ensure transparent billing. When creating SaaS offers in the Azure Marketplace, ISVs can define plans with various pricing strategies, such as usage-based or flat-rate billing. These plans, or SKUs, can be customized through free trials, BYOL (Bring Your Own License), or vCPU-based pricing for virtual machines. Both Azure and AWS allow flexible, metered billing based on usage. Azure also provides the ability to set customer discounts or negotiated pricing. Using Partner Center, you can configure and manage these offerings, providing flexibility for customers and partners to scale as needed. Like AWS Control Tower, Azure Lighthouse enables service providers to manage multiple customer Azure environments securely and at scale, offering enhanced visibility, control, and automation. For usage-based monthly billing, you can choose from predefined or custom pricing options (using metered billing APIs). Predefined options like per core, per node, or per pod let Microsoft bill customers based on hourly usage, billing them monthly. Learn more about usage-based pricing here: Setting Plan Pricing. Mapping AWS services to Azure services Your Marketplace offer may use multiple AWS services, and you can build the same offer using Azure services. However, this requires careful mapping to ensure your application functions seamlessly in the Azure environment. Here’s a quick overview of how popular AWS services map to Azure:: Networking: AWS VPC → Azure Virtual Networks (VNets) Compute Services: AWS EC2 → Azure Virtual Machines (VMs), Azure App Services (for web apps) Storage: Amazon S3 → Azure Blob Storage, Azure Data Lake Storage (for big data) Identity Management: AWS IAM → Entra ID Containers: EKS and Elastic Beanstalk → AKS and Azure App Services Serverless: AWS Lambda → Azure Functions Databases: Amazon RDS → Azure SQL Database, Azure Cosmos DB (for NoSQL) Azure for AWS professionals provides you with a more comprehensive mapping of different services. Let's take a deeper look into each of these areas. Cloud architecture and networking One of the primary differences between AWS and Azure lies in their cloud architecture and networking models. AWS uses Virtual Private Clouds (VPCs) to create isolated networks, while Azure employs Virtual Networks (VNets). Both services perform similar functions, but they have different terminologies and setups. For instance, in Azure, you'll be working with VNet Peering, Network Security Groups (NSGs), and Azure VPNs for secure networking. The goal is to map your AWS VPC setup to Azure VNets with ease. AWS needs a Nat Gateway for egress access whereas Azure does not need a Nat Gateway for default egress. AWS Subnets are pinned to Availability Zones (AZs) whereas Azure Subnets span across the AZs. Compute services: EC2 vs. Virtual Machines (VMs) AWS EC2 instances are one of the most widely used compute services, allowing you to run applications on virtual servers. In Azure, the equivalent service is Azure Virtual Machines (VMs). While both offer scalable compute resources, the key differences are in the range of VM sizes, configurations, and the management interface. When migrating from AWS EC2 to Azure VMs, it's important to assess the appropriate Azure VM sizes and configurations that match the performance of your EC2 instances. Additionally, Azure VMs support Azure Resource Manager (ARM) templates, which provide more automation for resource management. For those who have utilized EC2's Auto Scaling feature, Azure provides similar functionality through Azure Scale Sets. Storage: S3 vs. Blob Storage For object storage, AWS uses Amazon S3, while Azure uses Azure Blob Storage. Both services serve the same purpose — storing large amounts of unstructured data — but the underlying configurations, security features, and cost structures differ. While migrating from S3 to Blob Storage, it’s important to review your storage needs and adjust your application accordingly. Azure Blob Storage offers Cool and Archive tiers, which can be a great way to optimize storage costs for infrequently accessed data, and Azure's data redundancy options ensure high availability and durability. The Azure Storage Explorer tool also makes it easier for ISVs to manage their data after migration. Identity and Access Management (IAM) & billing: IAM vs. Entra ID IAM services on AWS and Azure differ in how they manage roles and permissions. AWS uses IAM for users, roles, and policies, while Azure uses Entra ID for IAM across cloud services. AWS organizes accounts through AWS Organizations, with IAM used for role-based access control (RBAC) and policies for service access. Azure’s structure involves Subscriptions and Management Groups, with Entra ID managing identity and access. Azure uses RBAC to assign roles at various levels (Subscription, Resource Group, Resource) and Azure Policies for governance and compliance. Azure Entra ID integrates with Microsoft services, like Office 365, SharePoint, and Teams, supporting identity federation, multi-factor authentication, and RBAC for granular permissions. It enhances governance and security across platforms. Azure handles billing management via subscriptions providing access to resources and can be reassigned to new owners. It offers three classic subscription administrator roles for resource access and management for billing and resource access. Container management: Elastic Beanstalk vs. Azure App Services and EKS vs. AKS For containerized applications, AWS offers Elastic Beanstalk for easy application deployment and management. Azure’s equivalent services include Azure App Services for simple web application hosting and Azure Kubernetes Service (AKS) for container orchestration. While Azure App Services is more suitable for traditional web applications, AKS provides a robust and scalable solution for microservices and containerized applications, similar to AWS’s Elastic Kubernetes Service (EKS). ISVs who are accustomed to Elastic Beanstalk for deploying containerized applications will find Azure App Services or AKS a seamless alternative, with Azure offering rich integrations with DevOps pipelines, CI/CD workflows, and container registries. Serverless: AWS Lambda vs. Azure Functions Both AWS and Azure support serverless computing, which allows developers to run code without managing servers. AWS offers Lambda, while Azure offers Azure Functions. Both services allow you to trigger code in response to events, such as file uploads or API calls. The key difference is that Azure Functions integrates deeply with other Azure services, such as Azure Logic Apps and Azure Event Grid. If your application leverages AWS Lambda, you will find that Azure Functions can serve as an excellent equivalent. Azure also provides Durable Functions, which extend Azure Functions for stateful workflows. Migrating from AWS Lambda to Azure Functions typically requires mapping your event-driven functions and configuring their triggers in the Azure ecosystem. Databases: RDS vs. Azure SQL and Cosmos DB When it comes to databases, AWS offers Amazon RDS for relational databases, and Amazon DynamoDB for NoSQL. Azure provides several alternatives, including Azure SQL Database for relational storage and Azure Cosmos DB for NoSQL storage. Both platforms support database scalability, automated backups, and high availability. If you are using Amazon RDS with services like MySQL or PostgreSQL, you can migrate to Azure Database for MySQL or Azure Database for PostgreSQL. Similarly, if you are using AWS DynamoDB, Azure’s Cosmos DB offers a global, scalable NoSQL database with low-latency access. Messaging: AWS SQS vs. Azure Service Bus Messaging services are crucial when your application handles high-throughput, asynchronous communication between different components. AWS offers Simple Queue Service (SQS) for messaging and SNS for pub/sub notifications while Azure offers Azure Service Bus and Azure Event Grid. Azure Service Bus provides similar functionality to SQS but offers additional capabilities like advanced message routing, dead-lettering, and sessions for handling ordered messages. If your application relies on a queuing mechanism for inter-service communication, you’ll want to map AWS SQS to Azure Service Bus. For event-driven architectures, Azure Event Grid can connect different services and trigger actions across Azure services. Security: Protecting your application on Azure When migrating from AWS to Azure, security is paramount. Both platforms offer strong frameworks to protect data, apps, and infrastructure. Azure provides a suite of integrated security services to maintain high security while enabling cloud scalability. AWS offers AWS Shield and WAF for DDoS and web application firewalls, while Azure offers Azure DDoS Protection and Azure Firewall for similar threat prevention. Azure Security Center monitors your security posture, and Azure Sentinel provides cloud-native SIEM (Security Information and Event Management) for threat detection and response. Microsoft Defender for Identity and Azure Entra ID Identity Protection integrate with Entra ID, ensuring your app security is tightly linked to user identity and governance. Compliance: Meeting regulatory standards on Azure Ensuring compliance with industry standards and regulations is crucial for many ISVs. Azure provides a robust compliance framework that aligns with global standards to meet the most stringent requirements. Whether your application deals with sensitive data or operates in highly regulated industries, Azure’s comprehensive compliance offerings can help you achieve the necessary certifications. Azure complies with key standards such as: GDPR HIPAA SOC 1, 2, and 3 ISO 27001 and other ISO standards FedRAMP Azure provides tools like Azure Policy for governance and Azure Blueprints for complex regulatory requirements. It offers a similar set of compliance certifications to AWS, with a stronger integration into Microsoft enterprise tools, easing compliance for businesses in regulated sectors. For apps handling sensitive data, use Azure Security and Compliance Blueprint to ensure regulatory adherence. Azure’s Compliance Manager helps track and manage compliance, simplifying the process of meeting industry standards.
