Docker with AWS Elastic Beanstalk

 Single Docker Container

 Multiple Docker Containers

AWS Cloud Kata for Start-Ups and Developers

Multi Container: Architecture

  Each environment has its own ECS Cluster   Supports a single ECS Task

definition per environment   The ECS Task is defined in

the Dockerrun.aws.json file   Supports multiple ELB

listeners for inbound traffic   Provides out of the box auto

scaling for ECS Tasks
