Docker
● “Docker allows you to package an application with all of its dependencies into a standardized unit”
● “Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.”
