Certified Kubernetes Application Developer (CKAD) – Overview, Benefits

CKAD is an open-source containerized solution for developing applications in Kubernetes. It enables you to create and customize containers at any stage of development, which allows your apps to run as microservices and scale from a single node.

For building the enterprise applications on the open container’s top, the OWF developed the framework based on building reliability and accessibility of modern technology. As with any other industry, plenty of companies offer services like Ckad.

CKAD also offers a free trial version for all users and offers robust security support. I will discuss the basic information related to CKAD exam certification in the following article.

CKAD exam certifies that candidates can design, build and deploy cloud-native applications for Kubernetes. This exam is an online proctored performance base test consisting of a set of performance-based tasks to be solved in the test.

What is CKAD?

Ckad is a platform that helps you develop Kubernetes-based applications easily. All you need to do is download their software, launch an app from the browser or app store, select the ‘Use A Single Node’ option, and you are done.

Certified Kubernetes Application Developer (CKAD)

You can then use the command line to interact with various pods. In this article, we have illustrated the basic working of Ckad to develop an application using it. Let’s learn how it works.

Who Can Have CKAD Certification?

The certification of Kubernetes Application Developer CKAD is for Kubernetes engineers, cloud engineers, and other IT professionals, who can perform the tasks related to building, deploying, and configuring cloud-native applications with Kubernetes. Before CKAD application, candidates can apply for six digits jobs. Besides this, they also have experience in different courses related to CKAD, which can establish experience and better knowledge towardsCKAD job details.

Benefits of Development With CKAD:

CKAD supports running a wide array of programs and services including Docker images from major companies such as Red Hat and Microsoft.Net and NodeJS and Java.Net Core frameworks from Google. They also support popular libraries like Azure Blob, Amazon Elastic Beanstalk, Azure Public, AWS Lambda, and many more. These APIs are also built with Ckad to serve the needs of different industries.

What Are Some Limitations of CKAD?

Many limitations are there in CKAD. First and foremost, it does not scale well due to scalability. Every time you create multiple pods, there is just one server running behind the scenes. While doing so, you can end up losing performance.

Also, there is no way to control the deployment and redeployment of pods inside your application. Another limitation is that it has many infrastructure-related issues that are difficult to fix. Thus, developers need to choose between Kubernetes and DevOps when developing applications.

If you wish to experience what other Kubernetes applications look like, you can take Ckad v3.7 in 2021. Initially released in 2020, it has received widespread acclaim and praise from customers across different industries.

If you are looking for Kubernetes with fewer restrictions and don’t mind keeping data securely, this is a perfect choice. The latest release has added several features such as multi-tenant Kubernetes services and many others.

Is CKAD Certification Worth Doing?

Everyone from the Kubernetes field may know that the CKAD exam is a tough one. Still, the main thing is after effects of CKAD certification, the earning of CKAD is an excellent way of delivering values to your organization and also it is a great source of personal pride. So, these main things prove that CKAD is worth doing, and a candidate can achieve a great future after qualifying for the CKAD certification.

CKAD Exam Summary:

There are only two chances for attempting and passing the exam of CKAD, and there are only 2 hours for the candidate to complete the exam. The exam is online proctored, but it is a performance-based task to be solved in a command line. The version on which the Kubernetes exam is based is v1.22. The cost of CKAD certification is approximately 375$, which includes one free retake.

CKAD exam paper consists of 30 multiple questions. You can get different exam guides, exam dumps, online lectures, pdf files, and other CKAD study materials from various websites such as Marks4sure.com, and the Kubernetes related sites. Other than this, the questions on this exam focus on the CKAD course categories listed, which I have shared below this topic.

Overview of CKAD Certification:

There are different sections/domains to explain this Certification, for example, deployment of an application, environment security & configuration of the application, observability and the maintenance of the application, designing and building the application, and networking & services.

Designing and Building of Application:

The container images are defined, built, and modified. The jobs are understood and cornered, the pattern for the design of a multi-container pod is understood, and persistence is utilized. The volume of those ephemerals is also used at the end of this section.

Deployment of Application:

To implement widespread deployment strategies, the primitives of the Kubernetes are used. Deployment should be understood. Even the working of the rolling updates is also understood, and for the deployment of the existing packages, the Helm Package Manager is used.

Services & Networking:

Network Policies basic understanding is demonstrated, and with the help of the services, access is provided and troubleshooting the application. For the exposition of the application, the ingress rules are used.

Observability and Maintenance of Application:

Logs of the container are used, and in the Kubernetes, the debugging is done. The deprecations of the API are then understood, and the checks of the health and problems are implemented, and at last, for the monitoring of the Kubernetes, the provided tools are used.

Environment, Configuration & Security of Applications:

For the extension of the Kubernetes, the resources are discovered and used. Limits, Quotas, and the requirements of the resources are then understood and defined clearly. ConfigMaps are understood, and secrets are created and then used. The security context and the service accounts are then understood at last.


CKAD certification is an amazing way to lead a successful professional career related to the Kubernetes field. In this article, I have discussed some important factors associated with CKAD so that you can understand the basic things about CKAD, so if you want to apply for this certification, then you can go through with this. https://www.marks4sure.com/CKAD-exam.html.
