AWS vs Azure

At a glance

Account structure and identity

AWS treats the account as the unit of isolation. Each account has its own root user, IAM principals, quotas, and bill, and AWS Organizations ties accounts together with organizational units, service control policies, and consolidated billing. Human sign-on across many accounts is typically handled by IAM Identity Center. Workloads assume IAM roles rather than holding long-lived keys. Because accounts are cheap to create, mature AWS estates contain dozens or hundreds of them.

Azure separates identity from resources more sharply. The Entra ID tenant (formerly Azure Active Directory) holds users, groups, and applications, and it is often the same tenant that already serves Microsoft 365. Under the tenant sit management groups, then subscriptions, then resource groups. A subscription is the billing and quota boundary; a resource group is a logical folder for resources that share a lifecycle. Azure role-based access control assigns built-in or custom roles at any of these scopes and inherits downward. Azure Policy enforces rules such as allowed regions or required tags across a management group.

The result is that an Azure subscription plays roughly the role of an AWS account, but identity in Azure is centralised in one tenant from the start. For companies that already manage users in Entra ID, this is the single most persuasive reason to prefer Azure. For companies without a Microsoft directory, AWS Organizations plus IAM Identity Center offers an equivalent end state with a different learning curve.

Compute and storage

EC2 instance families cover general purpose, compute, memory, storage, and accelerated workloads, with Graviton Arm generations alongside x86 options. Container services are ECS, EKS, and Fargate; Lambda covers functions. EBS provides block volumes and S3 provides object storage with lifecycle transitions between classes. Windows Server and SQL Server images exist on EC2 and are licensed per hour by default, with options to bring existing licences under specific conditions set by Microsoft.

Azure Virtual Machines are grouped into lettered series, such as burstable B, general purpose D, memory optimised E, compute optimised F, and GPU-equipped N series, each with generations and processor variants. Virtual Machine Scale Sets handle autoscaling. Azure App Service is a mature platform for web applications, and Azure Functions provides event-driven code. AKS is the managed Kubernetes service and integrates closely with Azure Container Registry and Entra ID. Managed Disks are the block storage layer, and Blob Storage, inside a storage account that also offers Files, Queues, and Tables, is the object store with hot, cool, cold, and archive tiers.

For databases, AWS has a broader list of distinct managed engines. Azure's strengths are Azure SQL Database, which is the managed home for SQL Server workloads, and Cosmos DB, a multi-model globally distributed database. Both platforms run managed PostgreSQL and MySQL and both have a data warehouse (Redshift on AWS, Synapse and Microsoft Fabric on Azure).

Networking and regions

AWS networking centres on the regional VPC with zonal subnets, security groups, network ACLs, and connections through peering, Transit Gateway, PrivateLink, Direct Connect, and Site-to-Site VPN. Azure's equivalent is the Virtual Network (VNet), also regional, with subnets, network security groups, VNet peering, Private Link, ExpressRoute for dedicated circuits, and VPN Gateway. The concepts map closely, and engineers moving between the two usually find the translation direct.

Azure has a large region list and a strong presence in countries where local data residency matters, including a number of regions in Europe, the Middle East, and Asia. Many Azure regions are paired with a second region in the same geography for replication. Availability zones exist in most major Azure regions but not all, so verify zone support for the region you plan to use. AWS regions all have multiple zones. Both providers also run separate sovereign or government clouds with their own account boundaries.

Hybrid connectivity is a stronger theme on Azure. Azure Arc extends Azure management to servers and Kubernetes clusters that run elsewhere, and Azure Stack brings Azure services into a customer's own data centre. AWS offers Outposts and related services for similar needs, but the Microsoft ecosystem makes hybrid a more natural fit on Azure.

Pricing model

Both platforms bill pay as you go with per-second metering on most virtual machines, separate charges for storage, transactions, and outbound data transfer, and region-specific prices. Commitment discounts exist on both: AWS Savings Plans and Reserved Instances, and Azure Reservations and the Azure savings plan for compute. Both offer interruptible capacity (Spot Instances on AWS, Spot Virtual Machines on Azure) at a discount.

The distinctive Azure lever is licensing. Azure Hybrid Benefit lets organisations apply existing Windows Server and SQL Server licences with active Software Assurance to Azure resources, which changes the economics for Microsoft-heavy workloads. Enterprises commonly buy Azure through an Enterprise Agreement or a Cloud Solution Provider partner rather than a credit card, and Azure cost management tools, budgets, and alerts are built into the portal. AWS provides similar budgeting through AWS Budgets and Cost Explorer. On both platforms, egress and idle resources are the usual sources of surprise bills.

Best fit for developers, startups and businesses

Developers who work in .NET, Visual Studio, and GitHub Actions find Azure's integrations direct, especially App Service and Azure Functions. Developers working in Linux, containers, and open-source tooling generally find more community material for AWS, though both platforms support all mainstream languages and both have capable CLIs and infrastructure-as-code support.

Startups often begin on AWS because of its ecosystem and startup programmes, but the Microsoft for Startups programme and Azure's generative AI services draw startups that build on OpenAI models through Azure OpenAI Service. Teams that plan to sell to enterprises running Microsoft 365 can also benefit from living in the same identity world as their customers.

Businesses with existing Microsoft agreements, Active Directory, Windows Server estates, or SQL Server databases usually get a lower total cost and an easier migration on Azure. Businesses that want the broadest set of managed services, the most regions, or a partner ecosystem built around a specific vertical are more likely to choose AWS. Both platforms carry the compliance attestations that regulated industries expect.

Each label states a quota level, a credit balance, or an enabled service and nothing beyond that.

The Buy Azure Accounts page lists Free Trial with $200 Credit ($25), Pay-As-You-Go with $200 Credit ($25), and AI Supported Pay-As-You-Go with $200 Credit ($80), plus Azure $1K Tier 1 Support Claude ($180) and Azure $5K Credit Account ($750). The labels describe a subscription type, a credit amount, or a support tier exactly as written; the underlying terms of any Microsoft credit are set by Microsoft.

After handover on either platform, review identity first: on AWS that means the root user and IAM, on Azure the tenant and subscription owners. The article on IAM users, roles, and policies across providers walks through both. See the Compare hub for other pairs. CloudAccountHub is independent; provider names are used for identification only.
