Should I use Kubernetes or EKS for production workloads?

For production workloads, the short answer is:

• Use Kubernetes if you want the platform itself and are prepared to run/manage it.
• Use EKS if you want managed Kubernetes on AWS with less operational burden.

A more practical framing is: EKS is Kubernetes, but AWS manages the control plane for you. So this is usually not “Kubernetes vs EKS” as two different things, but rather self-managed Kubernetes vs managed Kubernetes on AWS (EKS).

When to choose EKS

Choose EKS if you:

• Are already on AWS
• Want to reduce operational overhead
• Prefer AWS integration for:
  • IAM
  • VPC networking
  • Load balancers
  • EBS/EFS
  • CloudWatch
• Want a production-ready setup without managing masters/control-plane nodes
• Have a small/medium platform team and want to move faster

Pros

• AWS manages the control plane
• Easier high availability for Kubernetes core components
• Better integration with AWS services
• Less cluster maintenance than self-managed Kubernetes
• Good for most production use cases on AWS

Cons

• AWS-specific ecosystem and some vendor lock-in
• Costs can be higher than running Kubernetes yourself in some cases
• Still requires cluster/app/platform expertise

When to choose self-managed Kubernetes

Choose self-managed Kubernetes if you:

• Need full control over the Kubernetes stack
• Run on-prem, edge, or multiple clouds
• Have strong SRE/platform engineering capacity
• Need custom networking, security, or cluster behavior that managed offerings constrain
• Want to avoid AWS dependency

Pros

• Maximum control
• Works anywhere
• Potentially lower direct infrastructure costs in some environments

Cons

• You own upgrades, HA, etcd/control plane reliability, security patching
• More operational complexity
• Higher risk if your team lacks deep Kubernetes expertise

Practical recommendation

For most teams building production workloads on AWS:

Use EKS.

It gives you the benefits of Kubernetes without the operational burden of managing the control plane yourself.

Rule of thumb

• AWS + production + limited ops team → EKS
• Need full control / multi-cloud / on-prem → Self-managed Kubernetes
• Not on AWS → consider another managed Kubernetes offering (GKE, AKS, etc.)

If you want, I can also give you a decision matrix comparing EKS vs self-managed Kubernetes vs ECS, or help you decide based on your specific workload and team size.
