Industry Use Cases of Jenkins

How Jenkins came in role and what challenges it can solve ?

To do any integration to do anything manually it takes a lot of time and bound to errors thus to save our time we create some program which can do things what you are doing manually and benefit is that it can be used again and again without error i.e. Automation tools and jenkins do that for us.

Company comes with the product plan then Developer create software or Application with some code and push it to git repository as a backup but there is not a single team working on it, there may be various team working on different ends so then we need to integrate these codes, compile it and test it in the environments and followed many such processes finally they create a application

but, trouble don’t end here, if company launch some new feature again developer work on it, again merging codes then compilation so doing this all manually is time consuming.

let us take another example, suppose company is delivering some security application and experience some glitch so, in such cases there is a need of fast action, one cannot go for manual work because it is bound to client’s product’s security, there is a need of continuous action as soon as the code gets updates to achieve this goals we need a tool which monitors all the changes in the code and do further jobs accordingly i.e. Continuous Integration and continuous delivery.

so, Jenkins facilitates us continuous integration and continuous delivery in software and application projects by automating parts related to build, test, and deployment. This makes it easy for developers to continuously work on the betterment of the product by integrating changes to the project.

This tool is more about integrating multiple tools together and work together.

How Jenkins supports Continuous Integration and Continuous deployment-

In both cases, Jenkins describes a desired state and the automation server ensures that that state is achieved. Also, the velocity of releases can be increased since deployments are no longer bounded by personnel limitations, such as operator availability. Finally, Jenkins reduces stress on the development and operations team, by removing the need for middle of the night and weekend rollouts.

How Jenkins works and features -

In Jenkins, pipelines are created. it is a series of steps the Jenkins server will take to perform the required tasks of the CI/CD process. These are stored in a plain text Jenkinsfile. These steps are declared as commands with parameters and encapsulated in curly brackets. The Jenkins server then reads the Jenkinsfile and executes its commands, pushing the code down the pipeline from committed source code to production runtime. A Jenkinsfile can be created through a GUI or by writing code directly.

• Easy Installation: Jenkins is a platform-agnostic, self-contained Java-based program, ready to run with packages for Windows, Mac OS, and Unix-like operating systems.
• Easy Configuration: Jenkins is easily set up and configured using it’s web interface, featuring error checks and a built-in help function.
• Available Plugins : There are hundreds of plugins available in the Update Center, integrating with every tool in the CI and CD toolchain.
• Extensible : Jenkins can be extended by means of its plugin architecture, providing nearly endless possibilities for what it can do.
• Easy Distribution : Jenkins can easily distribute work across multiple machines for faster builds, tests, and deployments across multiple platforms.
• Free Open Source : Jenkins is an open-source resource backed by heavy community support.
