Containerized applications were a revolution in the area of software development. Also, there was a considerable rise in the popularity of container management and orchestration applications like Kubernetes.
Need for Kubernetes
Kubernetes is the most common open-source platform for containerized application deployment, scaling, and management across diverse sectors. It serves the roles of programming containers on a cluster and manages workloads to ensure operations as required. In combination with component interactions and their management, Kubernetes helps to characterize application components. It dramatically increases the ease of operations and portability of modern software systems.
Many organizations rely on these aspects for experts in the management and development of Kubernetes. No official certification for Kubernetes existed until recently. However, you can now receive official accreditation for your experience on Kubernetes using the Certified Kubernetes Administrator (CKA) exam.
Kubernetes bursts as one of the fastest open-source projects. To broaden the Kubernetes Administrative Network, the Cloud Native Computing Foundation (CNCF) has dedicated itself to continued growth in the broad spectrum of businesses and agencies that use Kubernetes.
For any DevOps professional, learning Kubernetes is necessary. DevOps engineers are still in demand. The Silicon Valley of India, Gurgaon, and Haryana presently offers DevOps engineers an average 20 percent salary than a software engineer. The average salary of DevOps engineers is around $140,000 to $200,000 a year. And the Kubernetes Administration certification is one of the most in-demand credentials.
Certification is a significant step in this process that enables certified administrators to rapidly develop their reputation and value in the job market and make it easier for businesses to employ high-quality teams more rapidly to sustain their development.
Know about the CKA program
The CNCF offers a certification program that allows users to prove their expertise in a realistic command-line environment. The purpose of the CKA program is to assure that CKAs are competent, knowledgeable, and able to carry out the Kubernetes administrators’ functions.
It is an online, tailored, performance-based examination that needs many command-line problems to be solved. Using a text editor, candidates should practice and learn useful shortcuts.
CKA is different from Kubernetes Certified Service Provider (KCSP). You can become a CKA without participating in a KCSP, but you have to hire at least three CKAs to become a KCSP. CKA program guarantees that CKAs have the expertise, experience, and abilities to fulfill Kubernetes administrators’ responsibilities.
Exam details
The online test consists of a variety of command-line performance-based items (problems) to solve. Candidates are expected to complete the tasks within 2 hours. The certification focuses on the competencies necessary today to be a good Kubernetes Administrator in the industry. First, it is essential to know about the exam before beginning the CKA exam preparation. The CKA test, along with the Linux Foundation, is the CNCF’s brainchild.
In July 2015, Google agreed to join the Linux Foundation with Kubernetes v1.0, and the CNCF was born. CNCF’s primary aim is to build sustainable ecosystems using Kubernetes. The CKA exam is a unique CNCF initiative to broaden an organizational culture that focuses on various high-quality container orchestration projects within a microservice architecture.
Preparation for the CKA exam is perfect for checking the exam skills. The CKA test aims to add standardization to the Kubernetes ecosystem and make this exam a worthwhile investment with the large-scale adoption of Kubernetes. But candidates must be mindful that the test is not as easy as they expect. The assessment examines the awareness of candidates on a realistic basis, rather than asking multiple-choice questions. The test also follows a rigorous curriculum, which means a need for CKA training before attending the exam.
- Cluster Architecture, Installation & Configuration – 25%
- Services & Networking – 20%
- Troubleshooting – 30%
- Workloads & Scheduling – 15%
- Storage – 10%
For your preparation, you need a CKA guide that describes all of the above fields. You can find the subtopics in each domain covered by the CKA exam with the study guide.
Free Exam Tip: Calm down and note that you have a free retake if something goes wrong. Even if you do not, this first attempt gives you a chance to consider the review method and draw conclusions before the second attempt. You may not need it, but the comfort you get helps you relax.
Pre-requisites
- Users should know Linux command line basics and Linux networking and service management.
- Solid comprehension of containers, particularly Docker, will be of value.
- The learning path explains Kubernetes based on Linux machines. It is comfortable to work with Linux shells.
- In the learning path, labs utilize virtual computers in public clouds. Previous experience with virtual machines in cloud environments is useful but not necessary.
Training is Mandatory
The next significant addition to any CKA guide concerns online training courses. To grasp all main concepts in Kubernetes, candidates can access a free “Introduction to Kubernetes” course by the Linux Foundation.
Furthermore, the Linux Foundation’s ‘Fundamentals of Kubernetes’ course aims to build upon the initial learning opportunities to prepare applicants for the CKA certification exam. Many training providers are also available for the preparation of CKA exams. Candidates can be assured of guidance with training courses by knowledgeable and qualified subject experts.
What the CKA course demonstrates?
A CKA showed the ability to configure and manage the Kubernetes clusters of the production stage. They can know critical concepts such as the Kubernetes networking, storage, protection, management, tracking and monitoring, system lifecycle, system integration, fundamental API objects, and creating simple use cases for users. This course helps you obtain the expertise needed to develop and deploy cloud-native applications in a cluster of Kubernetes. Animation and visualization series of well-designed sessions allow you to understand complex concepts quickly.
Build your cloud-native career right now
Kubernetes is today one of Cloud Computing’s top emerging technologies. Kubernetes saw the highest rise in job searches, over 173% compared to one year ago, as a recently reported survey report. The foundation of the cloud-native movement is Kubernetes. Linux Foundation’s training and certification and various training partners enable you to make career investment, learn Kubernetes, and succeed in your cloud projects.
