Docker - Introduction - Class 2 | DevOps Architect Free Training |

Docker is popular because it has revolutionized development. Docker, and the containers it makes possible, has revolutionized the software industry and in five short years, their popularity as a tool and platform has skyrocketed. The main reason is that containers create vast economies of scale.

Docker containers are process-isolated and don't require a hardware hypervisor. This means Docker containers are much smaller and require far fewer resources than a VM. Docker is fast. Very fast.

you don't put everything in a container the same way you would do with VMs (this is called separation of concerns and it results in more lightweight app components. It also gives speed to developers because different teams can work on their component separately).

Docker containers are, by default, quite secure; especially if you run your processes as non-privileged users inside the container. You can add an extra layer of safety by enabling AppArmor, SELinux, GRSEC, or another appropriate hardening system.
