Managed Kubernetes Comparison

Amazon EKS vs Azure AKS

Independent comparison for enterprise buyers. Updated May 2026.

Quick verdict: Choose Amazon EKS for organisations standardised on AWS where IAM, VPC and the broader AWS service catalogue carry the workload portfolio. Choose Azure AKS for Microsoft-aligned estates where Entra ID, Azure Policy and tight Visual Studio and GitHub integration shape the developer experience. The key differentiator is identity and tooling alignment with the surrounding cloud, not Kubernetes capability, which is broadly comparable.

Feature comparison

Amazon EKS provides a managed Kubernetes control plane on AWS with deep integration into AWS services. Workloads attach to IAM through IAM Roles for Service Accounts and Pod Identity, to VPC through the AWS VPC CNI plugin, to EBS and EFS for persistent storage, and to ALB and NLB for ingress. EKS Anywhere extends Kubernetes to on-premise environments, and EKS Hybrid Nodes allow on-premise compute to join EKS clusters managed in AWS, which suits enterprises with a mature AWS landing zone that need a consistent control plane across data centres.

Azure AKS is the managed Kubernetes service on Azure, with Entra ID integration through AKS-managed Microsoft Entra and Workload Identity, Azure CNI and Azure CNI Overlay for networking, Azure Disk and Azure Files for storage, and Application Gateway for ingress. AKS offers a free control plane in the standard tier, which reduces baseline cost relative to EKS for organisations operating many smaller clusters. The Premium tier introduces long-term support for Kubernetes minor versions, which appeals to regulated estates that prefer slower upgrade cadence.

For hybrid and multi-cluster scenarios, Azure Arc-enabled Kubernetes extends Azure governance, policy and monitoring across AKS, AKS on Azure Stack HCI, EKS, GKE and on-premise clusters. EKS offers comparable extension through EKS Anywhere and EKS Hybrid Nodes, with narrower reach into non-AWS clouds. Both platforms support Windows containers, although AKS has the more mature Windows node pool experience and remains the preferred option for organisations modernising .NET Framework workloads alongside .NET on Linux.

On autoscaling and operational tooling, both platforms support Karpenter or equivalent fast node autoscaling, GitOps via Argo CD or Flux, and Open Service Mesh or Istio. AKS has tighter integration with GitHub Actions and Visual Studio for developer workflows. EKS has a wider third-party add-on marketplace and a longer track record of large enterprise references.

Pricing comparison

Amazon EKS charges $0.10 per cluster per hour for the managed control plane, plus underlying EC2 or Fargate compute, EBS storage and data transfer. Extended support for older Kubernetes versions costs an additional $0.50 per cluster per hour. A typical EKS production cluster runs in the range of $5K–$50K per month depending on node count, instance type and reserved capacity commitments. The recurring buying-side trap is inter-availability-zone data transfer and NAT gateway charges, which can grow materially in chatty microservice estates.

Azure AKS charges nothing for the control plane in the standard tier as of May 2026, with paid Premium tier control plane pricing of approximately $0.60 per cluster per hour for long-term Kubernetes version support. Underlying Azure VM, managed disk and bandwidth costs apply normally. A typical AKS production cluster prices in the range of $4K–$45K per month at similar scale to EKS, with the free control plane providing a small but real advantage for fleets of low-utilisation clusters. The buying-side caveat on Azure is bandwidth and Premium Storage costs, which can exceed comparable AWS line items for high-throughput workloads.

When to choose Amazon EKS

Choose Amazon EKS if your organisation is standardised on AWS with material existing IAM, VPC and service integrations, if you operate workloads requiring deep AWS-native services such as S3, DynamoDB, Aurora or SageMaker, or if your portfolio benefits from EKS's broader AWS region footprint and reserved capacity options. EKS is also the pragmatic default for organisations with significant AWS spend commitments where consolidating Kubernetes on AWS strengthens negotiating position and simplifies enterprise discount programme reporting.

When to choose Azure AKS

Choose Azure AKS if your organisation is standardised on Microsoft with an existing Entra ID, Microsoft 365 and Azure landing zone footprint, if your developer estate uses Visual Studio, GitHub Enterprise and Azure DevOps, or if you operate Windows container workloads where AKS has the most mature Windows node pool experience. AKS is also a strong fit for organisations consolidating governance across AKS, on-premise and other clouds through Azure Arc, and where the free standard control plane meaningfully reduces baseline cluster cost.

Frequently Asked Questions

Is AKS cheaper than EKS?
The AKS standard control plane is free, while EKS charges $0.10 per cluster per hour. The saving is modest in single-cluster estates but meaningful across many low-utilisation clusters. Underlying compute, storage and bandwidth costs follow each cloud's pricing and typically dominate the bill.
Which is better for Windows containers?
Azure AKS has the more mature Windows node pool experience, including longer Windows Server LTSC support and tighter Active Directory integration through gMSA. EKS supports Windows node pools but is generally chosen by organisations whose Windows estate is incidental rather than central to the workload portfolio.
Can I run AKS and EKS clusters under one governance model?
Yes. Azure Arc-enabled Kubernetes extends Azure Policy, monitoring and GitOps to AKS, EKS, GKE and on-premise clusters. Anthos and Rancher offer comparable cross-cloud governance. Most multi-cloud Kubernetes estates standardise on one such control layer to avoid fragmented policy and observability.
How long does AKS or EKS take to deploy?
A production-ready cluster on either platform typically takes 4–12 weeks once landing zone, networking, identity and CI/CD integration are included. The cluster creation itself takes minutes; most of the timeline is the surrounding platform engineering required to meet enterprise security, monitoring and compliance baselines.
Which has better Kubernetes version support?
Both follow upstream Kubernetes within a few weeks of release. AKS Premium tier offers long-term support for selected minor versions, similar to EKS extended support. For regulated estates that prefer slower upgrade cycles, both vendors now provide a paid path to stay on an older minor version for an additional period.
