Nowadays we hear a lot about Kubernetes vs Docker but it is a quite misleading phrase. We will understand what people mean to say when they talk about Docker vs Kubernetes. As they both are not direct competitors. Docker is a containerized platform whereas Kubernetes is a container orchestrator for container platforms like Docker.

It’s not correct if we talk about docker without exploring containers. Containers solve critical issues of application development. We developers always face an issue when our code is running perfectly on the local environment but not on production. There can be multiple reasons behind it like different operating systems, different dependencies, or can be different libraries.

This problem can be solved with the help of containers as a developer can package up their application, including all the bins and libraries it needs to run correctly, into a small container image. And on production, we can use that image to run the application in any containerized platform. Containers are portable and scalable and can be scaled on the basis of our requirements.

In addition, scalability and portability containers provide many advantages over traditional virtualization. It has a small footprint and it requires only application and definition of bins and libraries. Unlike Virtual machines which have a complete copy of the guest operating system whereas in containers separation is done on kernel level without the need for a guest operating system. Containers don’t need to have multiple instances if all the applications are using the same libraries/packages. It allows an application to become encapsulated in a self-contained environment that allows for quicker deployments, closer parity between development environments, and infinite scalability.

DevOps and Cloud computing are joined at the hip, now that fact is well appreciated by the organizations that engaged in SaaS cloud and developed applications in the Cloud. During the COVID crisis period, most of the organizations have started using cloud computing services and implementing a cloud-first strategy to establish their remote operations. Similarly, the extended DevOps strategy will make the development process more agile with automated test cases.
