Hello Containers!
Explore the evolution from virtual machines to modern containers, focusing on their efficiency and portability. Understand the technological foundations like kernel namespaces and control groups, and learn how Docker made containers accessible. This lesson also covers container support on Windows and the dominance of Linux containers.
We'll cover the following...
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.
