🔰Jenkins & Industry Use Cases🔰

ello guys, Here I am come with new article in which we can see the How Industry Use the Jenkins Tool To automate the things.

We will see the use cases of Jenkins, but before that we have to learn basic about Jenkins.

Let’s start...

⚡ What is Jenkins?

Jenkins is an open-source automation tool written in Java with plugins built for Continuous Integration / Continuous Deployment or Delivery (CI/CD) purposes. Jenkins is used to build and test your software projects continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. It also allows you to continuously deliver your software by integrating with a large number of testing and deployment technologies. It is used to implement CI/CD workflows, called pipelines.

⚡ What is CI/CD?

The “CI” in CI/CD always refers to continuous integration, which is an automation process for developers. Successful CI means new code changes to an app are regularly built, tested, and merged to a shared repository. It’s a solution to the problem of having too many branches of an app in development at once that might conflict with each other.

The “CD” in CI/CD refers to continuous delivery and/or continuous deployment, which are related concepts that sometimes get used interchangeably. Both are about automating further stages of the pipeline, but they’re sometimes used separately to illustrate just how much automation is happening.

🔸 Continuous Integration (CI) :

In modern application development, the goal is to have multiple developers working simultaneously on different features of the same app. However, if an organization is set up to merge all branching source code together on one day (known as “merge day”), the resulting work can be tedious, manual, and time-intensive. That’s because when a developer working in isolation makes a change to an application, there’s a chance it will conflict with different changes being simultaneously made by other developers. This problem can be further compounded if each developer has customized their own local integrated development environment (IDE), rather than the team agreeing on one cloud-based IDE.

🔸 Continuous Delivery (CD) :

Following the automation of builds and unit and integration testing in CI, continuous delivery automates the release of that validated code to a repository. So, in order to have an effective continuous delivery process, it’s important that CI is already built into your development pipeline. The goal of continuous delivery is to have a codebase that is always ready for deployment to a production environment.

In continuous delivery, every stage — from the merger of code changes to the delivery of production-ready builds — involves test automation and code release automation. At the end of that process, the operations team is able to deploy an app to production quickly and easily.

🔸 Continuous Deployment (CD) :

The final stage of a mature CI/CD pipeline is continuous deployment. As an extension of continuous delivery, which automates the release of a production-ready build to a code repository, continuous deployment automates releasing an app to production. Because there is no manual gate at the stage of the pipeline before production, continuous deployment relies heavily on well-designed test automation.

In practice, continuous deployment means that a developer’s change to a cloud application could go live within minutes of writing it (assuming it passes automated testing). This makes it much easier to continuously receive and incorporate user feedback. Taken together, all of these connected CI/CD practices make deployment of an application less risky, whereby it’s easier to release changes to apps in small pieces, rather than all at once. There’s also a lot of upfront investment, though, since automated tests will need to be written to accommodate a variety of testing and release stages in the CI/CD pipeline.

⚡ What is plugins?

Plugins are the primary means of enhancing the functionality of a Jenkins environment to suit organization- or user-specific needs. There are over a thousand different plugins which can be installed on a Jenkins controller and to integrate various build tools, cloud providers, analysis tools, and much more.

⚡ What is pipeline?

Jenkins Pipeline (or simply “Pipeline”) is a suite of plugins which supports implementing and integrating continuous delivery pipelines into Jenkins.

A continuous delivery pipeline is an automated expression of your process for getting software from version control right through to your users and customers.

⚡ Why we use Jenkins?

With Jenkins, organizations can accelerate the software development process through automation. Jenkins integrates development life-cycle processes of all kinds, including build, document, test, package, stage, deploy, static analysis, and much more. Jenkins achieves Continuous Integration with the help of plugins. Plugins allow the integration of Various DevOps stages. If you want to integrate a particular tool, you need to install the plugins for that tool. For example Git, Maven 2 project, Amazon EC2, HTML publisher etc.

⚡ Features Of Jenkins :

Jenkins is more functionality-driven rather than UI-driven hence, there is a learning curve involved in getting to know what is Jenkins. Here are the powerful developer-centric features offered by Jenkins:

1. Easy Installation & Configuration -

Jenkins is a self-contained Java program that is agnostic of the platform on which it is installed. It is available for almost all the popular operating systems such as Windows, different flavors of Unix, and Mac OS. It is available as a normal installer, as well as a .war file. Once installed, it is easy to configure using its web interface.

2. Open-Source -

As it is open-source, it is free for use. There is a strong involvement of the community which makes it a powerful CI/CD tool. You can take support from the Jenkins community, whether it is for extensibility, support, documentation, or any other feature related to Jenkins.

3. Thriving Plugin Ecosystem -

The backbone of Jenkins is the community and the community members have been instrumental in the development (and testing) of close to 1500+ plugins available in the Update Center.

4. Easy Distribution -

Jenkins is designed in such a manner that makes it relatively easy to distribute work across multiple machines and platforms for accelerated build, testing, and deployment.

⚡ Advantages : -

  • Jenkins is being managed by the community which is very open. Every month, they hold public meetings and take inputs from the public for the development of Jenkins project.
  • As technology grows, so does Jenkins. So far Jenkins has around 320 plugins published in its plugins database. With plugins, Jenkins becomes even more powerful and feature rich.
  • Jenkins also supports cloud-based architecture so that you can deploy Jenkins in cloud-based platforms.
  • The reason why Jenkins became popular is that it was created by a developer for developers.

⚡ Industry Use Case of Jenkins :

Amping up scientific research with CI/CD powered by Jenkins :

To promote open science practices and support scientific communities while serving 11k registered users in 45 countries, D4Science introduced a new delivery pipeline that replaced their per-existing build platform.

Of course, they had to build and release their software framework (gCube) in a way that would support multi-project releases at scale — from 200+ Git repositories within the same day! It had to be fast, automate all release activities, and it had to deliver incremental releases to address user requirements quickly. Most of all, the solution had to be cost-effective.

Using Jenkins, they created an innovative approach to software delivery: a continuous integration/continuous delivery (CI/CD) pipeline, scalable, easy to maintain, and up gradable at a minimal cost.

⚡ Conclusion :-

Finally To Conclude, We can see How Jenkins is playing a key role in this Automation world. As the demand increase these technologies helps in giving more productivity to the organizations with lowering the cost.
