Why teams migrate from GKE to EKS
Good fit when
- +Teams consolidating onto AWS or needing EKS for broader AWS service integration.
- +Organizations requiring EKS-specific features like Fargate profiles or App Mesh.
- +Teams in AWS-heavy environments wanting consistent IAM across all services.
Strengths
- Deep integration with the full AWS service catalog (ALB, Secrets Manager, IAM).
- Fargate profiles for serverless pod execution.
- Larger ecosystem of EKS add-ons and marketplace integrations.
Tradeoffs
- GKE Autopilot simplicity is lost; EKS requires more node group management.
- GCP Workload Identity must be remapped to IAM Roles for Service Accounts (IRSA).
- GKE Gateway API configs need translation to AWS Load Balancer Controller.
Migration notes
- Remap GKE Workload Identity annotations to EKS IRSA annotations.
- Translate GKE ingress to AWS Load Balancer Controller or nginx.
- Migrate GCP Secret Manager references to AWS Secrets Manager.
- Plan node group sizing and Spot/On-Demand mix for cost optimization.
