What are containers Recap

Recap

Two ways of bundling an application with its environment and dependencies are containers and virtual machines . Both methods allow an application to be run with minimal differences between development and production, and both can be used to horizontally scale an application.

Multiple containers and VMs can be run on the same machine, but containers running on the same machine share the same low-level operating system [kernel]( https://en.wikipedia.org/wiki/Kernel_%28
operating_system%29 ). You will learn more virtual machines and how they differ from containers more in the next concept.
