AWS vs Azure: Services, Pricing & Which to Choose (2026)

Last verified: June 18, 2026  ·  Format: Comparison

AWS vs Azure is the comparison most teams reach when they pick a cloud, because Amazon Web Services and Microsoft Azure are the two largest hyperscale platforms and they overlap on almost every primitive. Both rent compute, object storage, serverless functions, managed databases, and identity over the internet, on demand and metered by use. The honest framing is fit-for-use rather than an overall winner: AWS leads on breadth and ecosystem, Azure leads on Microsoft-stack integration and hybrid scenarios, and the better fit depends on what you already run. This comparison walks the differences that actually change a decision.

We keep it practical. We start with an at-a-glance summary, compare services and ecosystem side by side, lay the two pricing models against each other, look at global reach and reliability, and close with a scenario-by-scenario guide to which cloud to choose. Service and pricing details below are drawn from each provider's documentation and were checked on June 18, 2026; always confirm current figures on the AWS and Azure sites before you commit, since both change often.

AWS vs Azure at a glance

Before the details, here is the shape of the comparison. AWS, launched in 2006, is the most broadly adopted cloud, with more than 200 services and the largest third-party ecosystem. Azure is Microsoft's cloud, built on the Azure Resource Manager (ARM) deployment model, with identity through Microsoft Entra ID (formerly Azure AD) and deep integration into the Microsoft stack. The two are far more alike than different: both are hyperscalers offering IaaS, PaaS, and SaaS, with equivalent core primitives, virtual machines, object storage, serverless, managed databases, and identity, and both target 99.99%-class SLAs.

The table below is the quick-reference version of the rest of this article. Each row is grounded in the two providers' own documentation, and the cautions under it matter: infrastructure counts are vendor-reported and savings estimates come from the vendors themselves.

Services and ecosystem compared

On core capability, AWS and Azure are near-peers. Both give you virtual machines, object storage, serverless functions, managed relational and NoSQL databases, and identity and access management. If you can build it on one, you can almost certainly build the equivalent on the other. The differences that matter are breadth, maturity, and how each cloud fits the rest of your toolchain.

Where AWS pulls ahead

AWS is the breadth-and-maturity leader. It began in 2006, offers more than 200 fully featured services, and is the most broadly adopted cloud, which in turn means the largest third-party ecosystem, the deepest community knowledge, and the widest pool of trained engineers. Its flagships, Amazon EC2 for compute, Amazon S3 for object storage, and AWS Lambda for serverless, are reference points the whole industry learned on. For a fuller tour of that catalog, see our what is AWS breakdown and the what is Amazon EC2 guide.

Where Azure pulls ahead

Azure's edge is integration, not raw count. It is built on the Azure Resource Manager (ARM) deployment model and uses Microsoft Entra ID (formerly Azure AD) for identity, which means it slots naturally into organizations already running Windows Server, SQL Server, and Microsoft 365. That tight coupling, plus strong hybrid tooling such as Azure Hybrid Benefit, makes Azure the path of least resistance for Microsoft-centric enterprises. To go deeper, read our what is Microsoft Azure breakdown and the what is Azure Virtual Machines guide.

The practical takeaway: if your decision is driven by the sheer number of building blocks and the size of the ecosystem, AWS has the advantage. If it is driven by how cleanly the cloud fits your existing Microsoft estate and identity, Azure does. Both can run the same workload; the friction is in the surrounding stack. The wider multi-cloud hub covers how teams combine both rather than choosing once.

Pricing models compared

Both clouds share the same billing philosophy, pay only for what you use, then layer commitment-based discounts on top. The structures look similar at a distance, but the details differ, and so does how each describes its savings. Comparing AWS vs Azure pricing fairly means matching like for like and reading every percentage as a vendor-stated ceiling.

How AWS prices

AWS starts with On-Demand (pay as you go), then offers three commitment paths: Savings Plans (commit to a steady amount of usage for a 1-year or 3-year term, up to 72% off for compute and machine-learning usage), Spot Instances (bid on spare capacity for up to 90% off, with the trade-off that instances can be reclaimed), and Reserved Instances (capacity reservations over a term). A Free Tier lets you start across many services without immediate cost.

How Azure prices

Azure also starts with pay-as-you-go, metered per second and billed per full minute, then offers Reserved capacity (1-year or 3-year), Spot pricing for interruptible workloads, and an Azure savings plan for compute, where Microsoft estimates savings of up to 11%-65% versus pay-as-you-go for a consistent hourly spend commitment. Azure also adds Azure Hybrid Benefit, which lets you apply existing Windows Server and SQL Server licenses to cut cloud costs, a lever AWS does not match in the same way. New accounts come with a $200 credit over 30 days.

The headline: the two pricing models are structurally similar, so do not pick a cloud on a single percentage. AWS publishes higher best-case ceilings (up to 72% on Savings Plans, up to 90% on Spot), while Azure's distinguishing lever is licensing reuse through Azure Hybrid Benefit, which can dominate the math for organizations with existing Windows and SQL estates. Model your own workload against current rates; the live pricing pages are the only authoritative source.

Global reach and reliability

Both clouds are genuinely global, organized into geographic regions with isolated zones inside them, and both target 99.99%-class SLAs on core compute. For most workloads, either platform can put capacity close to your users and let you spread across zones for resilience. The reach difference is rarely the deciding factor; the deciding factor is whether a specific region you need exists on the cloud you prefer.

AWS reports a footprint of 123 Availability Zones across 39 Regions as of June 2026. That number is vendor-reported and changes as AWS builds out capacity, so treat it as a date-stamped snapshot rather than a fixed fact. Azure maintains its own large region map and publishes it separately; rather than chase a head-to-head count that drifts month to month, the reliable approach is to check each provider's current region list for the specific geographies and compliance boundaries you require.

Which to choose: AWS or Azure

With the dimensions covered, the AWS vs Azure decision comes down to your context, not a scoreboard. Both are capable enough to run almost any workload, so map your situation to the cloud that removes the most friction. The scenarios below translate the comparison into a recommendation.

If your decision is genuinely close, that is a signal, not a problem: it usually means either cloud would serve you, and the tie-breaker is your existing skills and licensing. Many organizations run both deliberately, placing Microsoft-aligned workloads on Azure and cloud-native ones on AWS. The what is cloud computing guide covers the shared model both are built on, and the Cloud Tools hub places them alongside other providers.
