Using ElasticBeanstalk you still need to &quot;handle&quot; environments, applications.<p>This is a level of abstraction above ECS, which Beanstalk uses behind the scenes for multi-container installations.<p>If you think about it, it&#x27;s like Heroku for docker, you handle &quot;apps&quot;, and the rest is handled by Rack.<p>This is how I understand it.
