If you're just beginning to explore DevOps and CI/CD, one of the first tools you'll come across is Jenkins. It's a core part of modern software development that helps automate repetitive tasks and makes the release process faster and more reliable.

What Is Jenkins?

Think of Jenkins as an automated assistant. It keeps an eye on your code and runs important tasks for you, without needing someone to do them manually.

Whenever new code is pushed to a repository, Jenkins can immediately check if it works.

How Jenkins Works in Real Life?

Imagine you've written some code and pushed it to a version control system like GitHub. Jenkins detects that change and triggers a sequence of steps — called a pipeline. That pipeline might build the project, run automated tests, check for bugs, and, if everything looks good, prepare and even deploy a new version of the application.

All of this happens behind the scenes, automatically. You don't have to manually run tests or upload files — Jenkins takes care of it. This speeds up the development process, reduces the chance of errors, and gives the team more time to focus on building great features.

Why Jenkins Matters?

Modern software development moves fast. The more tasks you can automate, the less likely you are to miss steps or make mistakes. Jenkins simplifies the entire delivery process, making it smoother, more consistent, and easier to manage — especially when working in a team or releasing updates frequently.

For anyone new to DevOps, Jenkins is a great place to start. You'll see how to create a workflow where code is tested and deployed automatically, without needing to repeat the same steps over and over.
