Containers have revolutionized the IT world and it can be hard to know where to start. In this course, Docker Captain Nigel Poulton guides you through the basics all the way to proficiency.

You'll learn why we have containers and how they work. You’ll run through the basics like images, the Docker engine, and containers. With the basics out of the way, you'll then containerize an application and learn how to run it. Throughout the course, Nigel will demystify all the jargon and buzzwords. When you're done, you'll be ready to use Docker in the real world.

The Beginner’s Guide to Docker

While most of us were reaping the benefits of VMs, web scalers like Google had already moved on from VMs and were using containers.

A feature of the container model is that every container shares the OS of the host it's running on. This means a single host can run more containers than VMs. For example, a host that can run 10 VMs might be able to run 50 containers, making containers far more efficient than VMs.

Containers are also faster and more portable than VMs.
