Kubernetes, an open-source system for automating containerized application management, has seen numerous managed services emerge to simplify its maintenance and reduce costs. This article examines three prominent managed Kubernetes services: Google Kubernetes Engine (GKE), Azure Kubernetes Service (AKS), and Amazon Elastic Container Service for Kubernetes (Amazon EKS). GKE, as the pioneer, provides the most advanced and automated features, including automatic updates and high availability, while AKS and Amazon EKS have rapidly gained popularity since their launch in 2018. Despite AWS's widespread reach, GKE stands out for its mature capabilities and strong community engagement, evidenced by its substantial presence on platforms like Stack Overflow. Moreover, GKE and AKS offer free cluster management, whereas Amazon EKS incurs additional hourly costs. The competition among these services continues to evolve as they vie for supremacy in the Kubernetes hosting landscape, with Google's offering currently holding a significant edge in terms of maturity and cost-effectiveness.
