About Kubernetes Certification Training

Certs Learning’s Kubernetes Certification Training introduces you with the advantages provided by containers over the virtual machines.
You will understand why we need an orchestration tool for containers. You will also get to know the boundaries of Kubernetes – what it does and what is it not supposed to do.
You will also understand the inherent architecture of Kubernetes – master components, node components and the addons provided by it. The course will start off with learning the basic components of Kubernetes like Node, Pod, Deployment, Services, APIs etc and then teach you to create a local cluster using Ubuntu VMs.
You will also learn to deploy stateful and stateless apps on the cluster. Finally, you will learn, how to expose these app outside of the kubernetes cluster and will also get to know how to scale their apps either manually or using auto scaling. Learn the best security practices that must be followed during this container and cluster orchestration.

Why should you go for this Kubernetes Certification Training?

There is a huge shift in Devops from virtualization to containerization. Docker has been the buzzword in the technology sphere, in the recent past to ship applications as containers.
A research states that there are already 10,000 companies who have adopted containers for taking their application to production and there are already 185 million containers on use in the world. The rate of adoption of Docker is increasing by 40% every year. Now that Docker has become the most integral part of production environment, various organizations are now looking out for tools that can help them effectively manage and orchestrate their containers.
Here is when industries started adopting a Google open sourced tool called Kubernetes for effectively managing the containers.

Who should go for this Kubernetes Certification course?

This course is designed specifically for:
  • Professionals who want to Advance their career as a Devops Engineer
  • Professionals who want to ace the Certified Kubernetes Application Developer (CKAD) program by Cloud Native Computing Foundation
  • Individuals using containers to deploy applications to production

What are the pre-requisites for this Kubernetes Certification Training?

Following are the pre-requisites:
  • Basics of Devops and it’s need
