What is the purpose of containerization?

Containerization is a method of packaging and deploying applications in a way that makes them easy to run and scale. It involves packaging an application and its dependencies into a container, which is a standardized unit of software that includes everything the application needs to run, including the code, runtime, system tools, libraries, and settings.

Containers are self-contained and lightweight, so they can be easily moved between different environments, such as development, staging, and production. They are also isolated from the host system and from other containers, so they do not interfere with each other or with the host system.
