You've likely heard about Docker. It's one of the big buzzwords currently running through the IT industry. Docker is a Linux container technology that lets us package and ship our applications and everything it needs to execute into a standard format, and run them on all our existing Linux hardware.

That might sound like a virtual machine, and it's a good start on how to think about Docker containers. Docker containers are similar to virtual machines in that our application runs on what seems to be it's own hardware instance. Every Docker container has it's own virtualized filesystem, memory, storage, CPU cycles and so on.

Where Docker containers differ is they virtualize the operating system kernel, not the hardware. That means we can't run any operating system, we have to run Linux. However, we also don't need to install an operating system for every application we want to run. This makes our containers very lean.
