Part 1: What is Jenkins (CI/CD) and How does it work? Advantages of Jenkins


enkins is a very popular and famous CI (Continuous Integration) tool. Continuous Integration is very useful and it takes place a vital role in software automation and DevOps that requires various stages.
In this tutorial, we will explore What is Jenkins and why we use it? Advantages of Jenkins, What is Continuous Integration? Continuous Integration with Jenkins.

Nowadays, if you are a software professional then you should know all about the process from start to end. If you are interested in Jenkins then you are on a good platform, here I'll show you all the aspects of Jenkins and CI/CD.

What is Jenkins and why we use it?

Jenkins is an open-source automation tool for software development written in Java used for Continuous Integration purposes. We use this tool to automate software development. It is basically a server, that keeps an eye on the software development and when anyone changes the code on that particular place, the Jenkins detects that change and Take a pull of that code and trigger the build process and notified to the group of the person associated with this code, after the successful build automatically deploys the code the test environment and then production. For all the above processes, we need to configure Jenkins and create jobs in the pipeline. I this tutorial, we'll explore the pipeline and Jenkins jobs in the next articles. If you don't want to miss these articles, please subscribe, our team will notify you of new updates.

Using Jenkins is a great deal in software development, it automates the process and it detects the errors in a very early stage (at the time of commit or merge) and notifies the developers. It breaks the testing work in a small part so that tester can easily find out the errors and also get to know the defected chunk of codes. In Jenkins, there are a lot of plugins that help in the to-do section. If you want to automate some tasks then you have to install the built-in plugin for the same.

What is Continuous Integration?

The term Continuous Integration means Integration without breaking. it is a development practice in which the associated developers are doing the commits of their code changes in a shared repository many times in a day. When the commit and push happened in the associated branch then build is triggers. This build allows the developers and another associated person to detect the problems in codes early. In the Continuous Integration, there is so many other tasks done by CI/CD like deployment to the test server, Providing the test results, etc What is Jenkins (CI/CD) and How does it work?

Continuous Integration With Jenkins:

The software development process is a very big process and it take lot of observation and planning. Suppose you and your team are developing software and your team has written tons of codes and finally the development is completed and all the codes deployed to the test server for testing.
Wooowww... It sounds good and you are thinking that you will test and it will be deployed to the production. Right?
But, it's not a best practice, because what if, it failed in the testing phase? Will you or your team would be able to find out the cause of that failure? of course Yes.. :) but it takes a lot of time and it very hard to debug all the codes and find out the actual issue. And what is the guarantee after the fix your software will pass in the nest test?

Here Continuous Integration comes into the picture. And if we are talking about Continuous Integration, why not use Jenkins for this? In this tutorial, we already described why we should use Jenkins.
