What is a Container

Think like a Virtual Machine but:

• light weight
• great resource efficiency
• improved developer productivity

Where containers differ from VMs is the fact that they take advantage of the Linux kernel which comes with process isolation and virtualization capabilities.

These capabilities are control groups(allocating resources), and namespaces(restricting a processes access to other areas of the system).

Some real world examples would be the fact that a container has a specific place on the ship and a container lock, which keeps everything secure inside it.
