Docker Swarm is a great way to deploy Docker Containers on AWS or Azure, both of which are supported cloud providers for Docker Community Edition (CE) and Enterprise Edition (EE).

Executing Containers on all nodes in a cluster is easy, and the docker stats command lets you easily view the memory, CPU, network and IO usage of all Containers on an individual node.
