In episode #83 of Mobycast, we learned that containers are normal Linux processes. But they take advantage of powerful operating system functionality that gives these processes their container superpowers. In particular, we learned about namespaces and control groups and how these features give rise to containers.

This week on Mobycast, Jon and Chris wrap up their four-part series by discussing the runtimes and platforms used to run containers in production. We dive deep on ContainerD and RunC, arguably the most important container runtime out there. We also revisit our pseudo code example of how to build a container from scratch, bringing us full circle on our quest to understand the differences between virtual machines and containers.
