What is containerization?
When you package together all of the software code within a container along with all the necessary components such as dependencies, libraries, and frameworks, you have achieved containerization.
Why is it important?
The application within the container can be moved to any environment and can run on any infrastructure completely independent of that environment’s operating system and other various specs. The container is essentially a fully functional and portable computing environment.
How does that make the developers’ job performance more efficient?
Instead of coding on one platform or specific OS—doing which resulted in incompatibility issues that created bugs, glitches, and errors which the developers would spend a lot of time fixing—a contained application can be moved across any platform or any infrastructure and perform optimally on all of them without any bugs or glitches since it already contains everything that it requires to run successfully.
The term to summarize that independence is environment agnostic. Containers are exactly that, which means that the developer team gets to spend less time configuring the environment and can implement cost-saving practices.
