CKAD or Certified Kubernetes Application Developer
is an industry-recognized certification that verifies one’s expertise in building, testing, and deploying applications in a Kubernetes environment. With the rapid adoption of containerization and microservices, Kubernetes has emerged as the de facto container orchestration platform, and the demand for certified Kubernetes professionals has surged significantly. In this article, we will dive deeper into the CKAD certification, its importance, and how to prepare for it.
The CKAD certification is designed by the Cloud Native Computing Foundation (CNCF) in collaboration with The Linux Foundation. The CNCF is a non-profit organization that hosts and sustains open-source projects related to cloud-native computing, including Kubernetes. The CKAD certification is aimed at developers who work with Kubernetes on a daily basis and have a thorough understanding of the Kubernetes API primitives and application deployment best practices.
The CKAD certification exam is a hands-on, performance-based exam that tests one’s practical skills in designing and deploying containerized applications in a Kubernetes environment. The exam consists of a set of performance-based tasks that must be completed within two hours. The exam environment is a live Kubernetes cluster, and the tasks are designed to simulate real-world scenarios that developers typically encounter when working with Kubernetes. The exam is proctored and can be taken online from anywhere in the world.
The CKAD certification is highly valued in the industry, and the demand for certified Kubernetes professionals is on the rise. According to a recent survey by the Cloud Native Computing Foundation, the demand for Kubernetes skills has increased by 1400% since 2016. The average salary of a CKAD certified professional ranges from $100,000 to $200,000 per year, depending on the location, experience, and other factors.
Preparing for the CKAD certification requires a significant amount of effort and dedication. The exam tests one’s practical skills in Kubernetes, and hence, it is essential to have hands-on experience with Kubernetes. The following are some of the key areas that one must focus on while preparing for the CKAD certification:
Kubernetes API primitives: The exam tests one’s understanding of the Kubernetes API primitives, such as Pods, Deployments, Services, ConfigMaps, and Secrets. It is essential to have a thorough understanding of these primitives and how they are used in application deployment.
Application deployment: The exam tests one’s ability
to deploy containerized applications in a Kubernetes environment. One must have hands-on experience with tools like kubectl, Helm, and Kubernetes manifests to prepare for this section.
Service networking: The exam tests one’s understanding of how Kubernetes services work and how to configure service networking in a Kubernetes cluster.
Storage: The exam tests one’s understanding of how to provision and use persistent storage in a Kubernetes environment.
Security: The exam tests one’s understanding of Kubernetes security best practices, such as RBAC, network policies, and pod security policies.
There are several resources available online to help one prepare for the CKAD certification. The official CKAD curriculum by the Linux Foundation is an excellent starting point for preparing for the exam. The curriculum covers all the essential topics that one must master to pass the exam. Additionally, there are several online courses, practice tests, and study materials available on platforms like Udemy, Coursera, and LinkedIn Learning.
Taking mock exams is an excellent way to prepare for the CKAD certification. Several online platforms offer practice tests that simulate the actual exam environment and test one’s practical skills in Kubernetes. These practice tests are an excellent way to identify one’s strengths and weaknesses and focus on areas that need improvement.
In conclusion, the CKAD certification is a valuable asset for developers who work with Kubernetes on a daily basis. The certification validates one’s practical skills in designing, deploying, and managing containerized applications in a Kubernetes environment
