Docker starts to look like a competitor to virtualization environments like VMWare VSphere deplyments. In the following knowledge base article Docker Reference Architecture: Docker Datacenter Best Practices and Design Considerations there is a very interesting presentation on how to migrate a datacenter to docker.
Docker Datacenter (DDC) is the enterprise container platform from Docker to be used across the entire software supply chain. It is a fully-integrated solution for container-based application development, deployment, and management. With integrated end-to-end security, DDC enables application portability by abstracting your infrastructure so that applications can move seamlessly from development to production.
