Virtual machines are of great importance, and although we cannot work without them, there are some areas in which virtual machines are lagging behind. For example, if you want to run a single application in an isolated environment, you have to set up and run a full operating system before you're able to do so. This will have its own boot up time and will consume a lot of resources when loading its binaries and libraries. In turn, this will limit the number of VMs you can run on a single physical machine.
So, what is containerization? Containerization is similar to a virtual machine which runs in an isolated environment without consuming a huge amount of system resources. Instead of loading a full operating system, containerization uses the base kernel of a required operation system and loads only the libraries required by our desired application...
