Lately Docker has been gathering momentum and becoming increasingly popular both as a tool to aid development and as one to aid deployment and operations. It is a container tool that utilizes Linux kernel features like cgroups and namespaces to isolate network, file, and memory resources without incurring the burden of a full, heavyweight virtual machine.1
There are countless platforms and frameworks available today that either support or integrate tightly with Docker. You can deploy Docker images to AWS (Amazon Web Services), GCP (Google Cloud Platform), Azure, virtual machines, and combinations of those running orchestration platforms like Kubernetes, Docker Swarm, CoreOS Fleet, Mesosphere Marathon, Cloud Foundry, and many others. The beauty of Docker is that it works in all of those environments without changing the container format.2
