Ensuring the reliability of containerized cloud environments

Managing dependencies and binaries across many applications and customers requires significant efforts. Having realized the need for a comprehensive-yet-compact mechanism for achieving system portability, the Docker people have combined some of the capabilities of Linux cgroups (https://en.wikipedia.org/wiki/Cgroups) and namespaces into a single and easy-to-use package so that applications can consistently run on any IT infrastructure (bare-metal servers and virtual machines) without any tweak and twist of application code. The resulting package is the Docker image (https://docs.docker.com/engine/docker-overview/), and the following benefits accrue from using out of this standardized image. The Docker platform is a collection of capabilities used to take care of the life cycle activities of Docker images and their container instances.

Let's understand more about Docker platform with the help of the following points:
