Top Kubernetes Certifications to Land a High-paying Job in 2020

Last updated on by Digamber
With the introduction of the container deployment technique, Kubernetes evolved as a popular framework to run distributed system resiliently.

There was a time when running multiple applications on one physical server used to be very problematic.

It was nearly impossible to specify how much of a CPU resource should the applications consume. This caused various sorts of problems like the underperformance of the applications.

Why Need Kubernetes Certifications?

One way to combat this constraint was by using virtualized deployment. This technique enabled running multiple virtual machines on a single physical server. Now various applications could run on different virtual devices on the same physical server.

Virtualized deployment has its benefits, as it enables better consumption of server resources and allows better scalability. It also reduced hardware costs.

After the virtual machine deployment era, came the container deployment technique. It is not much different from virtual machines. The difference being, container deployment has alleviated isolation properties that allow sharing of an operating system between the applications running on the server.

In virtual machines, each VM had its operating system and other resources. In container deployment, applications can share the OS making the containers lightweight.

Containers are very similar to VM’s as they too have their own processing space, memory, filesystem, CPU, etc. Boxes are getting more and more popular due to the abundance of advantages they provide.

Kubernetes is a framework to deal with containers and run distributed systems. Kubernetes could help you with deployment patterns, can govern canary deployment, regulate scaling and failover.

Kubernetes can balance the traffic load and make the deployment stable. Kubernetes can provide service discovery. Kubernetes gives you with Storage orchestration, automated rollbacks, and rollouts, self-healing, bin packing, configuration, and secret management, etc.

This us how useful Kubernetes is. So no doubt, if you can do all these on Kubernetes, companies will not flinch even a little to hire you.

The only problem is- how do they know that you know Kubernetes for real? To make them realize you know Kubernetes for real, you would need to show them some certifications.

You need to get certified in Kubernetes. Once you have got the certification, you will have plenty of advantages like-

  • You can serve as an asset for the Companies that rely on k8s.
  • You would get an additional certification to boast in your resume, making you more experienced.
  • Once you are a certified Kubernetes expert, you will have many job opportunities ahead of you with a handsome salary.

A Kubernetes expert could easily comprehend SaaS, and thus it would aid you in boosting your skillset.

These were just some of the benefits of getting Kubernetes certification.
It takes some hard work to pass these Kubernetes certifications, but once you do that, you could fetch a better salary than you would without this certifications. Some of this certification are also meant for organizations and enterprises.

If you are enthusiastic about Kubernetes, you must be wondering what Kubernetes certification do you need to pass. In this article, I am going to tell you the same thing.

Kubernetes Certification Options

While you could find a variety of platforms offering different courses to learn Kubernetes, the standard certifications are only 4 in number.

CNCF is offering these Kubernetes certifications. CNCF stands for the cloud-native computing foundation.

This body takes care of the development and management of the Kubernetes platform.

An aggregate of two certifications is available for people aspiring to learn Kubernetes or become a Kubernetes expert.

The same organization CNCF offers two more certifications for vendors or organizations. We will look at all four of this Kubernetes certification in detail in this article.

CKA – Certified Kubernetes Administrator

This certification program is meant for those professionals aspiring to get a job based on their Kubernetes skills. Once you pass this certification program, recruiters will not think twice to realize that you are a Kubernetes specialist.

This certification is valid for 3 years. Once you complete CKA certification, you will be transformed into a Kubernetes administrator. You will have all the capabilities and knowledge to regulate the Kubernetes platform and carry out the various task on it.
