The Art of Containerization

What is Containerization?

It is a technology that packages the applications and their dependencies into a single self contained unit called containers that allows them to run across different environments.

Above diagram demonstrates concept of containerization:

• It has runtime Engine (that can be docker , podman etc) which provides the technology to enable running units called container.

• The containers running are lightweight unit that has application and dependencies without actually having full Guest OS compared to Virtual machine.

• Containers have Container Images ideally using OCI images that can be run with the help of Container Runtime.

• Containers share the kernel of the Host OS.

• Containers offers More Cloud Native Approach where these containers can be individually scaled up/down.
