At a core level, DevOps is a methodology that accentuates collaboration between IT engineers and developers. The objective of DevOps is to eliminate the functional silos that earlier separated IT teams from development teams and made it problematic for them to communicate or reinforce each other’s efforts.
When an organization takes a DevOps approach, IT engineers and developers function closely together to determine what software is developed, how it’s deployed, and how troubles arising after deployment get resolved and inform the next development cycle.
DevOps is an ideology rather than a rigid set of tools and practices. However, a medley of technologies and procedures enables or enhances DevOps processes. They include methods such as continuous integration/continuous delivery (CI/CD), which means implementing and pushing out application updates quickly and continuously. They also extend to the usage of tools such as Git to conduct source control, making heavy use of cloud computing to build software environments that are more flexible and scalable. Automated configuration management tools are also utilized to fasten up software deployment and environment provisioning.
Why is DevOps important?
DevOps unlocks benefits for businesses and their customers by streamlining software delivery processes and removing the friction between development and IT teams.
This includes the following
- Application updates are quicker and less expensive to implement within a CI/CD pipeline. This lets organizations respond more quickly to changes in the market and provide cutting-edge features to users regularly.
- Automation tools that DevOps teams often use help to reduce costs while boosting the reusability and repeatability of configurations and environments, which benefits scaling businesses.
- DevOps practices enhance security by formalizing software delivery practices, which decreases the risk of oversights that lead to security vulnerabilities.
Engineers also get an advantage from DevOps. Because the DevOps notion strongly facilitates automation, working as a DevOps engineer means spending less time on boring work such as configuring a server manually or deploying an application release, and more time-consuming tasks that are more creative and authentic, such as planning updates to an application architecture or evaluating a new cloud service.
DevOps can also make the lives of engineers easier by making it quicker and simpler to rectify problems. If there is a bad application release, engineers can resolve it quickly by pushing an update out through their CI/CD pipeline.
By acquiring DevOps skills, engineers can increase their value to businesses while, at the same time, making themselves eligible for more enjoyable jobs
Types of DevOps certifications
When you set out to take a DevOps course or gain a DevOps certification, you’ll notice that they have three main classifications:
- Introductory courses and certifications – These courses majorly focus on DevOps basics.
- Advanced courses and certifications – These would be better for more sophisticated types of DevOps skills and tools. However, they do not focus on a single platform or company.
- Courses and certifications tied to practicing DevOps in a particular context. Examples of these types of courses include using a certain public cloud or a distinct container orchestration platform.
Your objectives will help you decide which type of certification or course to pursue
