• AWS Elastic Beanstalk is divided into two environments
  • Web Server Environment:
    • This hosts web application and handles http(s) requests
  • Worker Environment
    • This hosts a web application and handles background jobs and long running jobs

    • The loadbalancer is hosted on top of EC2 instances which are part of AutoScaling group (Scaling).

      • deploying applications
      • collecting metrics & logs
