Docker and Kubernetes certification training programs are a great way to get the skills you need to work with these technologies. These courses are taught by industry experts, and provide you with the hands-on experience you need to develop applications. Certification proves your expertise and makes you more marketable.
Getting a Docker and Kubernetes certification is a good way to distinguish yourself from other IT professionals. Certifications are less important for engineers with a lot of experience, but they can be useful to those who are looking to change careers and transition from on-premises development to the cloud. For example, if you've been working with virtual machines and want to transition to containers, this certification can help you get there faster.
Once you're sure you're ready for a certification exam, you can sign up for a course from the Linux Foundation. The course covers the basics of using Docker and Kubernetes, and focuses on building apps in containers. It also has a practice exam, which will help you determine if you're ready for the real thing.
In a high-level deployment environment, a container is a lightweight, resource-efficient container that contains a bundle of code and dependencies. A container can run applications on any platform, including those that can't be used in traditional virtual machines. By contrast, a virtual machine must virtualize the entire operating system and all software, which means it's resource-intensive.
The Certified Docker and Kubernetes Application Developer (CKAD) certification is a professional-level certification that focuses on application development and deployment on Kubernetes. Candidates for this certification should have some previous experience working on a team and using containers. They should have some production experience as well.
The Certified Docker and Kubernetes Application Developer (CKAD) certification is one of the most popular certifications in the industry. Designed for architects and DevOps professionals, this exam is two hours long and covers various concepts in a problem-solving format. Taking the CKAD exam is free and will allow you to show your expertise.
Managing clusters at scale can be challenging. A key component to managing these environments effectively is observability. Descriptive monitoring data helps application teams to make informed decisions about the state of their application. Fortunately, Kubernetes comes with basic monitoring capabilities. In addition, there are now a variety of open-standard monitoring tools, including OpenTelemetry and Prometheus.
