DevOps methodology recognizes the interdependence of the two groups namely the Development and the Operations groups. By integrating these functions as one team or department, DevOps helps an organization deploy software more frequently, while maintaining service stability and gaining the speed necessary for more innovation.

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. In a way, Docker is a bit like a virtual machine. But unlike a virtual machine, rather than creating a whole virtual operating system, Docker allows applications to use the same Linux kernel as the system that they’re running on and only requires applications be shipped with things not already running on the host computer. This gives a significant performance boost and reduces the size of the application.

Containerization with Kubernetes
Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications.
Kubernetes (aka k8s) is an open source orchestrator, donated to the community by Google, who has been using it internally for many years. It has become the de facto standard for container scheduling, and can scale up to the biggest deployments or down to a cluster of Raspberry Pi boards.
