Industry Use case of Jenkins
Jenkins is a free and open source automation server. It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery(CI/CD).
The Jenkins project was originally named Hudson, and was renamed after a dispute with Oracle, which had forked the project and claimed rights to the project name.
Benefits of Jenkins
Easy installation
Jenkins is a self-contained Java-based program, ready to run out-of-the-box, with packages for Windows, Linux, macOS, and other Unix-like OS.
Easy configuration
Jenkins can be easily set up and configured via its web interface, which includes on-the-fly error checks and built-in help.
Plugins
With a number of plugins in the Update Center, Jenkins integrates with practically every tool in the continuous integration and continuous delivery toolchain
Continuous Integration and Continuous Delivery
As an extensible automation server, Jenkins can be used as a simple CI server or turned into the continuous delivery hub for any project.
A GIF to show how Jenkins works:
The problems usually faced by the developers are:
Developers had to wait until the complete software is developed for the test results.
There was a high possibility that the test results might show multiple bugs. It was tough for developers to locate those bugs because they have to check the entire source code of the application.
Continuous feedback pertaining to things like coding or architectural issues, build failures, test status and file release uploads was missing due to which the quality of software can go down.
The whole process was manual which increases the risk of frequent failure
With the help of Jenkins all the above issues was solved with ease.
Case Study of Topdanmark
Topdanmark, a Danish insurance company offering a customer service platform that allows clients to easily and quickly manage their insurance, investments and pensions
With roughly 400 IT-related employees in the company and just about 80 on the operations team, the rest of the developers support approximately 2,000 other employees.
There are six-man Dev-Tools team who maintain the server platform that runs most of the company’s client/customer-related business applications.
Topdanmark has two Jenkins setups, legacy and CI/CD. In legacy setup, They have test, integration, release, and production environments. In CI/CD setup, they have a non-production and a production environment.
The legacy setup is part of a pre-scheduled handheld deployment cycle, customized to whichever team uses it. Due to all the customizations, it could take several days from the developer request to having a working Jenkins instance. This off course take several time but using CI/CD will make it easy and fast.
Jenkins is a very advance tool of DevOps that is making things extremely easy and fast. Using this tool industries are really making their technology better and could be able to provide their service with much better user experience.
