EKS vs AKS: which managed Kubernetes service should you choose?

Amazon Elastic Kubernetes Service (EKS) and Azure Kubernetes Service (AKS) are two of the most widely used managed Kubernetes platforms for running production workloads. Both remove the burden of managing the Kubernetes control plane while integrating tightly with their respective cloud ecosystems.

This guide compares Amazon EKS and Azure AKS across pricing, networking, identity, autoscaling, upgrades, hybrid deployments, and operational overhead. It also explores what managed Kubernetes doesn't solve and why modern platform teams increasingly need a developer platform that supports both developers and AI coding assistants.

Neither platform is universally better. If you're already committed to AWS or Azure, the decision is usually straightforward. If you're evaluating both clouds, understanding the operational differences becomes much more important.

Amazon Elastic Kubernetes Service (EKS) is AWS's managed Kubernetes platform.

AWS manages the Kubernetes control plane, including the API server, etcd, availability, and upgrades, while customers manage worker nodes, networking, workloads, and supporting infrastructure.

Because EKS closely follows upstream Kubernetes and integrates deeply with AWS services such as IAM, EC2, VPC, ECR, RDS, and CloudWatch, it's a popular choice for organizations already invested in the AWS ecosystem.

Azure Kubernetes Service (AKS) is Microsoft's managed Kubernetes platform.

Like EKS, Microsoft operates the Kubernetes control plane while customers manage workloads and worker nodes. AKS integrates closely with Microsoft Entra ID, Azure networking, Azure Monitor, GitHub, and Azure DevOps, making it a natural choice for organizations standardized on Azure.

AKS also provides a more opinionated operational experience, with additional automation around upgrades and cluster management.

Verdict: AKS can reduce costs for development environments through its free control plane. For production workloads, infrastructure costs such as compute, storage, networking, and data transfer have a much greater impact than Kubernetes management fees.

Verdict: EKS integrates tightly with AWS networking and VPC services, while AKS provides more networking options and generally requires less networking expertise to operate.

Verdict: Organizations already using AWS typically prefer EKS because it integrates naturally with IAM and other AWS services. Microsoft-centric organizations often find AKS simpler to operate thanks to Entra ID integration and additional automation.

Verdict: Both platforms support hybrid and serverless deployments. The better choice usually depends on which cloud ecosystem your organization already uses.

Both platforms deliver production-ready managed Kubernetes, so the decision usually comes down to your existing cloud strategy rather than Kubernetes itself.

Choose Amazon EKS if you:

• Already run most workloads on AWS
• Depend heavily on AWS services such as IAM, VPC, EC2, RDS, or S3
• Want maximum flexibility when configuring Kubernetes.
• Have an experienced platform engineering team managing AWS infrastructure.

Choose Azure AKS if you:

• Standardize on Microsoft Azure.
• Use Microsoft Entra ID for identity and access management.
• Prefer a more automated Kubernetes experience.
• Rely on Azure DevOps, GitHub, or other Microsoft services.

If your infrastructure is already standardized on one cloud provider, there is rarely a compelling reason to migrate purely because of Kubernetes.

Choosing a managed Kubernetes service is only one part of building an internal platform.

Organizations still need deployment automation, developer self-service, secrets management, preview environments, governance, managed services, and operational tooling. Increasingly, they also need a platform that allows AI coding assistants to perform these same tasks securely alongside developers.

While EKS and AKS provide managed Kubernetes, they leave much of the developer platform to external tooling. Northflank brings these capabilities together in a single platform, allowing both developers and AI coding assistants to provision infrastructure, deploy applications, create preview environments, and manage workloads through the same governed interface.

Amazon EKS and Azure AKS manage Kubernetes, but they don't provide the complete platform developers use every day. Teams still need to build or integrate CI/CD, Git-based deployments, preview environments, managed databases, secrets management, RBAC, audit logging, and developer self-service before application teams can ship software efficiently.

Northflank provides that platform layer while deploying workloads into your existing EKS or AKS clusters through self-serve BYOC. Your applications continue running inside your own AWS or Azure account, while developers and AI coding assistants use the same platform to provision infrastructure, deploy applications, create preview environments, manage databases, and operate workloads through governed workflows powered by Northflank Skills.

Organizations choose Northflank because it combines:

• Deploy into your existing EKS or AKS clusters: Continue using your existing cloud account, networking, and Kubernetes infrastructure while adding a complete developer platform on top.
• Git-based deployments and CI/CD: Build, deploy, and promote applications directly from Git with automated deployment pipelines, rollbacks, and environment promotion.
• Preview environments: Automatically create isolated preview environments for every pull request with temporary URLs and production-like infrastructure.
• Managed infrastructure services: Provision PostgreSQL, MySQL, MongoDB, Redis, RabbitMQ, MinIO, object storage, jobs, cron jobs, and GPU workloads alongside your applications.
• Enterprise security and governance: Manage secrets, RBAC, SAML/OIDC SSO, audit logging, network policies, and deployment permissions from a single control plane.
• AI-native platform operations with Northflank Skills: Claude Code, Codex, Cursor, Gemini CLI, and other AI coding assistants can provision infrastructure, deploy applications, create preview environments, provision databases, troubleshoot deployments, manage secrets, configure networking, and operate workloads using natural language while remaining within your organization's RBAC, audit logging, and governance controls.
• Multi-cloud flexibility: Deploy the same applications across AWS, Azure, GCP, OCI, CoreWeave, or on-premises infrastructure while using the same platform and developer experience.
• Self-serve BYOC: Applications run inside your own cloud account with no markup on the underlying compute, giving platform teams full ownership of their infrastructure.

Rather than replacing EKS or AKS, Northflank extends them into a complete internal developer platform. Developers and AI coding assistants use the same platform to provision infrastructure, deploy applications, create preview environments, and manage production workloads, while platform teams retain full control over governance, security, and the underlying Kubernetes clusters.

Neither platform is universally better. Amazon EKS is typically the better choice for organizations already invested in AWS, while Azure AKS is often the better fit for organizations using Microsoft Azure and Entra ID. The right choice depends more on your existing cloud ecosystem than Kubernetes itself.

AKS offers a free control plane tier for development and non-production workloads, while EKS charges for every control plane. For production environments, however, pricing is broadly similar because infrastructure costs such as compute, storage, and networking usually make up the majority of Kubernetes spending.

AKS generally provides a more opinionated and automated experience, particularly around upgrades and identity management. EKS offers greater flexibility but typically requires more Kubernetes and AWS expertise to operate effectively.

Yes. Both platforms run upstream Kubernetes, so most workloads can be migrated using standard Kubernetes manifests, Helm charts, or GitOps workflows. The biggest migration challenges are usually cloud-specific services such as networking, storage, identity, and load balancers rather than Kubernetes itself.

No. Neither platform includes a complete application delivery platform. Teams typically integrate GitHub Actions, Azure DevOps, Argo CD, Jenkins, or similar tools to build and deploy applications.

Yes. Both platforms support GPU-enabled Kubernetes nodes for AI training and inference workloads. The choice typically depends on which cloud provider already hosts your infrastructure rather than any major Kubernetes capability differences.

For many organizations, yes. While EKS and AKS manage Kubernetes, they don't provide everything developers need to build and ship software efficiently. Most engineering teams still require deployment pipelines, preview environments, secrets management, developer self-service, RBAC, audit logging, and managed services. Platforms like Northflank provide those capabilities while deploying applications into your existing Kubernetes clusters.

Amazon EKS and Azure AKS are both mature managed Kubernetes platforms. EKS is generally the better fit for AWS-native organizations that want maximum flexibility and deep integration with AWS services, while AKS is often the stronger choice for organizations standardized on Microsoft Azure and Entra ID.

Choosing between EKS and AKS is ultimately a cloud decision. Building a developer platform is a separate one. Whether your Kubernetes clusters run on AWS or Azure, Northflank adds the deployment automation, developer self-service, governance, preview environments, managed services, and AI-native workflows needed to turn managed Kubernetes into a complete internal developer platform. With Northflank Skills, developers and AI coding assistants can provision infrastructure, deploy applications, create environments, and operate workloads from the same governed platform.
