With its incredible ability to bundle and run applications, containers have gained huge popularity in the market these days. Container-based microservices architectures have significantly changed the way how software development and operations teams test and deploy modern software applications.
While the use of containers is proliferating in multiple IT scenarios, it’s not a simple plug-and-play. The process gets highly complicated when it comes to executing them at scale. Deploying containers bring along new challenges and added complexity. Managing them is not easy.
You need an automated system to manage Linux containers that run applications and make sure that there is no downtime. Say, for instance, whenever a container goes down, there should be another container that starts without delay.
That's how Kubernetes solves the problem. Kubernetes provides a way to schedule and deploy those containers along with scaling them to the desired state and manage their lifecycles. Using Kubernetes helps to deploy container-based applications in a portable, scalable and extensible way.
Once you have clustered together groups of containers, Kubernetes allows you to manage these clusters easily and efficiently. It provides you with a framework to run distributed systems resiliently and keeps containerised apps up and running.
