In recent years, the process of software development has undergone a myriad of changes. With DevOps gaining popularity, organizations have been able to come up with innovative solutions at a never-seen-before pace. By coordinating the developmental work of the different software teams, DevOps presents a unified platform with clearly defined processes for organizations to implement the software development life cycle.
The reason for the immense popularity of DevOps is the fact that it is continuously evolving. One of the significant developments that have set a buzz in the world of DevOps is that of Jenkins DevOps. This article delves into the world of Jenkins DevOps and tries to understand how Jenkins is affecting the world of DevOps.

Jenkins is highly flexible, and one can add multiple plugins to it. That way, the functionality of Jenkins can be altered to suit the individual needs of the project in hand.
In the software development life cycle, a team encounters various stages such as initial development and build, testing, and quality assurance followed by things like packaging, analyzing, and deploying. Now, a tool that might be the best for building may not be feasible for packaging or vice versa. In such a situation, DevOps Jenkins does the brilliant job of integrating the different tools involved in the running of functional or UI tests, continuous integration, or continuous delivery.
The process of getting Jenkins and DevOps to your local system is a rather simple one. All you have to do is go to the official site and download the zip file from there. Once downloaded, extract the file and initiate a dedicated folder for the installation process. Usually, your system will show a dedicated folder path before starting the process of installation.

Multiple organizations are going for Jenkins DevOps because they go beyond merging the texts of numerous developers to testing them simultaneously. For a massive deployment, such testing takes away various downstream problems. With the Jenkins DevOps model, the process is automated to a large extent as every piece of merged code is at a production-ready stage at every point.
As an IT professional involved in any part of the software development life cycle, Jenkins will empower you to have complete control over the workflow and manage the continuous integration/continuous delivery (CI/CD) pipeline promptly. Along with that, several plugins may be used to maximize the functionality of Jenkins DevOps for your technical needs.
Most of the functionality of Jenkins DevOps revolves around the fact that it is useful in any project because of its various plugins. These plugins are superpowers that allow Jenkins to take up a DevOps role depending on the situational demands.
