AWS Elastic Beanstalk Cluster Mode

AWS Elastic Beanstalk introduces Cluster Mode, a new deployment mode that allows you to run and manage multiple applications on shared infrastructure in your account. This mode is powered by Amazon EKS and offers cost savings and enhanced features.

New Features

  • Run multiple applications on pooled infrastructure.
  • Event-driven autoscaling.
  • OpenTelemetry-based observability to Amazon CloudWatch and third-party providers.
  • AWS Secrets Manager integration.
  • HTTPS by default via AWS Certificate Manager.

Deployment Modes

  • Standard Mode: Existing Elastic Beanstalk experience.
  • Cluster Mode: New mode running on Amazon EKS.

What to do

  • Create an environment in the Elastic Beanstalk console and select Cluster Mode.
  • Deploy with the AWS CLI, GitHub Action, or agent skills.

Cluster Mode is available in all commercial AWS Regions where Elastic Beanstalk is available. There is no additional charge for Cluster Mode; you pay for the AWS resources your applications consume.
