Containerization of applications brings many benefits, including the following: Portability between different platforms and clouds—it's truly write once, run anywhere. ... Improved security by isolating applications from the host system and from each other. Faster app start-up and easier scaling.

What is containerization and why it is necessary?

Put simply, containerization allows applications to be “written once and run anywhere.” This portability is important in terms of the development process and vendor compatibility. It also offers other notable benefits, like fault isolation, ease of management and security, to name a few.

What is the point of containerization?

Containerization allows developers to create and deploy applications faster and more securely. With traditional methods, code is developed in a specific computing environment which, when transferred to a new location, often results in bugs and errors.
