Benefits of Kubernetes Certification

As an IT professional, you must be aware that Kubernetes is a very in-demand skill right now in IT. Many system engineers and practitioners dedicate their time to upskilling themselves and getting the Kubernetes certification. So today, in this article, we will see why so many professionals value the Kubernetes certification and how exactly Kubernetes work. We will also prepare you with Kubernetes interview questions so you are ready to use your knowledge in practicality.

If you’re new to this, let us tell you what Kubernetes is. Kubernetes is a top-rated open-source platform for container orchestration. Although it is a platform that carries out the deployment, scaling, load balancing, and other programs similar to a PaaS, Kubernetes is not a PaaS. The main reason is that Kubernetes carries out its activities at a container level and not at a hardware level.

To master the skills required to become a Kubernetes expert, you must get a Kubernetes certification.

Types of Kubernetes Certifications

The Cloud Native Computing Foundation and Linux Foundation launched 3 Kubernetes certifications in 2017. Even today, these certifications are prevalent, and you can choose the right type of certification according to your needs. The 3 certifications for Kubernetes are:

1. Certified Kubernetes Application Developer (CKAD)

As a Kubernetes application developer, you can design, build, configure, and expose cloud-native applications. The CKAD certification will test your understanding of all the core Kubernetes concepts. You will also learn how Kubernetes service and networking work.

2. Certified Kubernetes Administrator (CKA)

Getting a Kubernetes administrator certification is more complicated than getting the other certifications. To qualify for the certification, the applicant must score at least 75% on the test. In this test, you will again be tested on your knowledge and understanding of the core Kubernetes concepts. Other than that, it will be seen whether you are qualified enough to handle the responsibility of a Kubernetes administrator. The duties will include installation, configuration, and management of Kubernetes clusters.

3. Certified Kubernetes Security Specialist (CKS)

To get a Kubernetes security specialist certification, you will first need to get the CKA certification. CKS is an advanced certification that upskills an individual to secure container-based applications and platforms during all phases of the Kubernetes process.

Benefits of getting a Kubernetes Certification

If you want to get any certification, you need to do it for the right reasons. So let’s see some of the top benefits of getting a Kubernetes certification:

1. Helps you pave the way for a career in DevOps

If you’re looking to make a career switch from system engineering to a role in DevOps, a Kubernetes certification will clear your path for the journey. Kubernetes is the default choice of many businesses, and if you are skilled in it, you will be the obvious choice for the job.

2.Makes you stand out in the job market

A Kubernetes certification in your resume will provide the hiring manager with the proof they need regarding your knowledge and understanding of the platform. In addition, this certification will make you look like a promising candidate for the job. Even if the position you are applying for doesn’t necessarily need a Kubernetes certification, it will still show them your passion for learning about new technologies.

3. Boosts your career

As more and more companies start using Kubernetes in their workings, the need for more Kubernetes professionals will be created. So knowing will give you an upper hand resulting in a career boost. You can apply for these jobs before it becomes a competitive space.

4. Makes you a Kubernetes expert

The unique thing about the Kubernetes certification is that a lot of hands-on practical knowledge is required to clear the exams. This means not everyone can clear these exams. So when you pass the tests and get certified, you become a Kubernetes expert.

5. Offers you better pay

When you are an expert in a field, and there aren’t that many others to give you any competition, you get a chance to negotiate for a better salary. And you also get a lot of choices among companies as many tech companies require Kubernetes experts now.

Most common Kubernetes interview questions that you might want to look into

Once you’ve acquired your Kubernetes certification, you must prepare for the interviews. So here are some of the most common Kubernetes interview questions:

1. What are K8s?

K8s is the abbreviation for Kubernetes. It comes from there being 8 letters between K and s.

2. How to perform maintenance activities on the K8s node?

You must perform a safety drain to perform maintenance activity on the K8s node first. Once you complete the kubectl drain, you can do the maintenance activity.

3. How is Kubernetes different from Docker Swarm?

There has been a long debate on Kubernetes vs. docker. Docker swarm doesn’t have a robust cluster. It cannot do auto-scaling, but its scaling is 5X faster than Kubernetes. Docker also doesn’t have a GUI.

4. What is orchestration when it comes to software and DevOps?

Orchestration means integrating multiple services that automate processes and synchronize information from time to time.

5. How do we control the resource usage of POD?

To control the resource usage of POD, you will have to use limit and request.

6. What are the various K8s services running on nodes?

There are two types of K8s services on node: executor services and master services.

So, to conclude

You need to get a Kubernetes certification if you’re an IT professional. Being well-skilled in Kubernetes will open up plenty of opportunities for you in the space. In addition, many companies are looking into the benefits of container orchestration. This increases the demand for Kubernetes experts. So claim your expertise by getting the Kubernetes certification.

Three types of certifications are popular in Kubernetes; CKAD, CKA, and CKS, each with a different difficulty level and requirements. Depending on the certificate you choose to do, you will find yourself fitting into different roles.

We have also discussed some common Kubernetes interview questions. So hopefully, this article will help you understand the scope of Kubernetes and whether the certification is for you or not.
