The 4 major container orchestration choices — GKE (Google) / EKS (AWS) / AKS (Azure) / ECS (AWS-proprietary) — are compared in depth. We cover the 3 Kubernetes standards and AWS's proprietary ECS, plus Serverless options, multi-cloud support, and the learning curve.

| GKE Standard (e2-standard-4 node) | $130 + Control Plane $73 = $203 |
| GKE Autopilot (4 vCPU + 16 GB Pod) | ~$185 + Control Plane $73 = $258 |
| EKS (t3.xlarge node) | $121 + Control Plane $73 = $194 |
| EKS Fargate (4 vCPU + 16 GB) | ~$170 + Control Plane $73 = $243 |
| AKS (D4s v5 node) | $140 + Control Plane $0 (Free) = $140 |
| ECS Fargate (4 vCPU + 16 GB) | ~$170 |

Which is easiest to use: GKE, EKS, or AKS?
GKE Autopilot has the lowest operational overhead. EKS shines with deep AWS integration, while AKS is attractive for its free Control Plane and Azure integration. GKE has the highest Kubernetes purity (Google originated K8s).
What is the difference between ECS and Kubernetes?
ECS is AWS's proprietary orchestration platform and is simpler. EKS / GKE / AKS are based on standard Kubernetes. Choose K8s-based services for multi-cloud portability; ECS is sufficient if you're AWS-only.
How much do Control Planes cost?
GKE Standard $0.10/h, GKE Autopilot $0.10/h + Pod billing, EKS $0.10/h, AKS Standard $0.10/h (Free Tier available), ECS free (only Fargate / EC2 costs).
What Serverless options are available?
GKE Autopilot (Pod-based billing, fully Google-managed), EKS Fargate (Pod-based), AKS Automatic (GA in 2024), and ECS Fargate. All 4 services offer Serverless K8s/Container options.
How is multi-cloud support?
GKE Enterprise (formerly Anthos) provides fleet management, EKS Anywhere allows on-prem deployment, and AKS integrates with Azure Arc. GCP is the most advanced in this area.
How do Workload Identity options compare?
GKE: Workload Identity (KSA ↔ GSA), EKS: IRSA (IAM Roles for Service Accounts), AKS: Workload Identity (Entra ID Federation), ECS: Task Role.
What about Service Mesh options?
GKE: Anthos Service Mesh (managed Istio), EKS: AWS App Mesh + Istio, AKS: Open Service Mesh (deprecated) / Istio, ECS: AWS App Mesh. Istio has the highest adoption rate.
What is the learning curve?
ECS is the easiest to learn (only AWS concepts). K8s-based services have many concepts, but GKE Autopilot is beginner-friendly. EKS / AKS assume Kubernetes knowledge.
