For many companies, DevOps is no longer just a buzzword, but rather, an entire culture. With increasing demands for quicker developmental strategies and continuous application deployments, the need for skilled DevOps professionals is only going to compound in years to come.
Although the field is constantly innovating, the ability for DevOps professionals to prove their expertise isn’t always straightforward. Obtaining a DevOps certification is one way for potential job candidates and employees to validate and demonstrate their skills, offering a competitive edge over others vying for the same positions.
We have put together a complete guide on DevOps certifications including some of the top DevOps certifications currently in demand.
What is a DevOps certification?
A DevOps certification is a designation that demonstrates specific competency in skills and subject matter that are needed in order to be a successful DevOps professional. These various certifications are typically obtained following an assessment, educational course, or performance review and they prove that the candidate met rigorous standards.
Why should I consider a DevOps certification?
Obtaining a DevOps certification is beneficial for both securing a new position as well as advancing a current one. More than 91% of employers believe IT certifications play a significant role in the hiring process and that such certifications are reliable predictors of future employee success.
If you are looking to pivot into a new role or technology, a DevOps certification can help provide better job opportunities. According to research, 97% of HR professionals and hiring managers use certifications as a deciding factor between equally qualified candidates, while 98% use them to confirm a candidate’s subject matter expertise. As DevOps continues to be adopted in more organizations, the field will become increasingly competitive, making any type of solid evidence of DevOps expertise even more critical.
Even if you aren’t looking to change positions, the benefits of a DevOps certification are still applicable. One of the obvious ways is with improved skills and knowledge. The information you gain from a certification program will only enhance your current capabilities. By learning DevOps methodologies, you also learn how to work in a team of cross-functional team members, including QA, developers, operation engineers, and business analysts.
DevOps positions are consistently ranked among the highest paying salaries in the industry, especially those related to cloud. By obtaining an in-demand certification, you are not only increasing your chances of being offered one of these positions, but you are also improving your likelihood for bonuses, promotions, or pay bumps.
Top DevOps Certifications in 2019
Because DevOps is not a single tool but an entire practice that combines with other tools and technology, no one certification will cover it all. Instead, a variety of certifications prove beneficial for DevOps practitioners based on market needs and industry trends.

Kubernetes is an open-source container management system that automates the process of deploying and managing multi-container applications at scale. Kubernetes paves the way for DevOps by enabling the team to keep pace with the requirements for software development, making it a power player in the world of DevOps certifications.
The Cloud Native Computing Foundation (CNCF) and the Linux Foundation collaborated to organize the Kubernetes certification program which validates professionals working on this software. There are two certification options: Certified Kubernetes Administrator (CKA) and Certified Kubernetes Application Developer (CKAD).
Certified Kubernetes Administrator
The CKA program tests the skills, knowledge, and proficiency that a Kubernetes Administrator should possess. The CKA exam is online and consists of a performance-based set of problems that the candidate must solve in a command line within three hours. The test focuses on general Kubernetes features such as:
- Application lifecycle management
- Installation and validation
- Core concepts
- Cluster maintenance
- Logging and monitoring
Certified Kubernetes Application Developer
This CKAD certification is built for professionals that execute core practices of the Kubernetes ecosystem. Candidates should be skilled in designing, building, exposing, and configuring native cloud applications for Kubernetes. They should also be aware of application techniques for OCI-Compliant Container Runtime, Cloud native application concepts, infrastructure, and programming languages such as Python, Go, or Java.
This exam certifies a candidate’s experience, skills, application expertise, and familiarity with the Kubernetes environment. It lasts two hours and covers core concepts, configuration, multi-container pod, observability, pod design, and services and networking.
Azure DevOps Engineer Expert
Microsoft Azure is a cloud computing service similar to AWS and the Google Cloud Platform. It offers a wide variety of services, including web servers, email servers, databases, file storage servers, virtual machines, user directories, and more. Incorporating Azure and DevOps simplifies and speeds up the entire DevOps process, providing faster and more reliable deployments.
Among the several Azure certifications, Azure DevOps Engineer Expert certification validates the skills and expertise of Azure DevOps professionals specifically. Ideally, these Azure professionals will already be working as DevOps engineers, designing and implementing DevOps best practices for the version control, build, release, compliance, testing, and infrastructure as code by using Azure technologies.
