EKS vs GKE vs AKS - Evaluating Kubernetes in the Cloud
The document evaluates the top three Kubernetes providers: Amazon EKS, Google GKE, and Azure AKS, covering aspects such as supported versions, maintenance, features, networking, and security. Key takeaways include that GKE is the most mature platform, while EKS is considered the most unmanaged, and both EKS and AKS require more hands-on management or automation compared to GKE. The summary includes comparisons of control plane upgrades, service level agreements, and security options across the three platforms.
