Why look beyond AWS EKS
AWS EKS provides a managed Kubernetes control plane, offloading much of the operational burden of running Kubernetes to AWS. Its deep integration with the broader AWS ecosystem, including IAM, VPC, and various storage and networking services, makes it a natural choice for organizations already heavily invested in AWS. However, several factors might lead organizations to consider alternatives.
Cost can be a significant driver. While EKS charges a flat hourly fee for the control plane, the underlying compute (EC2 instances or Fargate) and other AWS resources can accumulate. Competing managed Kubernetes services from other cloud providers may offer different pricing structures or simpler billing. Operational philosophies also vary; some alternatives prioritize simplicity and developer experience over extensive configurability, which can be beneficial for teams without dedicated Kubernetes experts. Furthermore, multi-cloud strategies or regulatory requirements might necessitate distributing workloads across different cloud providers, making a vendor-agnostic or alternative cloud-specific Kubernetes solution more appealing. Finally, specific features or integrations with non-AWS services could be better supported by alternative platforms.

How to pick
Selecting an AWS EKS alternative involves evaluating your technical requirements, existing cloud investments, budget constraints, and team's expertise. The decision matrix below outlines key considerations:
1. Existing Cloud Provider Affiliation:
- If your organization is heavily invested in Google Cloud, Google Kubernetes Engine (GKE) is a logical choice due to its seamless integration with other Google Cloud services and the advanced features derived from Google's origin of Kubernetes.
- For organizations with a significant presence in Azure, Azure Kubernetes Service (AKS) offers deep integration with Azure AD, Azure Monitor, and robust hybrid cloud capabilities via Azure Arc, simplifying management within the Microsoft ecosystem.
- If you are not tied to a specific hyperscaler or are exploring multi-cloud, DigitalOcean Kubernetes or Linode Kubernetes Engine offer simpler, cost-effective alternatives for smaller deployments or development environments.
2. Feature Set and Management Overhead:
- For advanced automation, serverless Kubernetes options, and cutting-edge features, GKE (especially Autopilot mode) and AKS are strong contenders. They aim to reduce operational burden significantly by managing more aspects of the Kubernetes environment.
- If your team requires a comprehensive, opinionated platform with integrated developer tools, CI/CD, and a consistent experience across hybrid environments, Red Hat OpenShift provides a more complete application development platform on top of Kubernetes.
- If simplicity and minimal management overhead for core Kubernetes functionality are priorities, DOKS and LKE provide straightforward managed services that are easier to get started with compared to the extensive feature sets of the hyperscalers.
3. Cost Considerations:
- EKS charges for the control plane. GKE and AKS offer a free control plane (with charges for underlying compute), which can be a significant cost saving for smaller clusters or development environments.
- DigitalOcean Kubernetes and Linode Kubernetes Engine are typically more cost-effective for smaller to medium-sized workloads, offering competitive pricing for compute resources without complex tiering. Always analyze total cost of ownership, including compute, networking, storage, and any added services.
4. Hybrid and Multi-Cloud Strategy:
- For strong hybrid cloud needs, EKS Anywhere, AKS with Azure Arc, and Red Hat OpenShift are designed to provide consistent Kubernetes experiences across on-premises, edge, and multiple cloud environments.
- If your strategy involves running Kubernetes across various public clouds, OpenShift provides a unified platform. GKE Anthos also offers robust multi-cloud and hybrid capabilities.
5. Team Expertise and Developer Experience:
- Consider your team's familiarity with the specific cloud provider's ecosystem and tooling. Migrating to a new cloud provider might incur a learning curve.
- Platforms like DigitalOcean Kubernetes and Linode Kubernetes Engine are often praised for their developer-friendly interfaces and clear documentation, which can accelerate onboarding for new teams or projects.
- OpenShift provides a rich developer console and integrated tools that can enhance productivity, especially in larger enterprise environments.
