AWS adds Cluster Mode to Elastic Beanstalk on shared EKS clusters

AWS introduced Cluster Mode for Elastic Beanstalk, running applications as containers on Amazon EKS clusters the service creates and operates. It sits alongside the EC2-based Beanstalk Standard, but customers cannot choose the cluster or its Kubernetes version, and environments sharing the same VPC subnets share a cluster.

• Environments with the same VPC subnets share one EKS cluster, created in about ten minutes
• Cluster and Kubernetes version cannot be chosen; subnets and IAM roles cannot be changed without recreating the environment
• Cluster infrastructure access is service-managed via API, CLI or console only
• New charges apply: a flat hourly EKS fee per cluster plus an EKS Auto Mode management fee
