Introduction
In the last article, we have discussed about Microservices (Link), a comparison with Monolith architecture, and the benefits of containerization for software/applications in the Cloud Era.

Now I want to share about Kubernetes, How a large number of containers are operated, created, and managed? How develops & owns Kubernetes with benefits of it.
Orchestration of Containers
Kubernetes is an orchestrator. More specifically, it’s an orchestrator of containerized apps. This means it helps us deploy and maintain applications that are distributed and deployed as containers.

What is Kubernetes ??
Kubernetes is a production-grade, OpenSource platform that orchestrates containers for application deployment, scaling, and management of applications within and across computer clusters (or Cloud.)

It was originally designed by Google and it was open-sourced and handed over to the Cloud Native Computing Foundation (CNCF) in the summer of 2014. Kubernetes services, support, and tools are widely available.

How to read Kubernetes?
It is Greek for a pilot or helmsman (the person holding the ship’s steering wheel). People pronounce Kubernetes in a few different ways.
Many pronounce it as Koo-ber-nay-tace, while others pronounce it more like Koo-ber-netties. You can simply call it K8s

How much Kubernetes is being used
Google has been running containerized workloads in production for more than a decade. Whether it’s service jobs like web front-ends and stateful servers, infrastructure systems, virtually everything at Google runs as a container.
Approx two Billion (yes 2Billion ) containers run at Google per week!
Kubernetes Benefits
Kubernetes provides you with a framework to run distributed systems resiliently. It takes care of scaling and failover for your application
Service discovery and load balancing
Storage orchestration
Automated rollouts and rollbacks
Automatic bin packing
Self-healing
Secret and configuration management
Conclusion
With modern web services, users expect applications to be available 24/7, and developers expect to deploy new versions of those applications several times a day. Containerization helps package software to serve these goals, enabling applications to be released and updated in an easy and fast way without downtime.
It is not the end but it is a beginning. Sharing more about Kubernetes in the next article.
