Amazon makes changes to its production environment every 11.6 seconds. Facebook modifies its site at least a couple of times every day. In terms of software development, releases at this incredible cadence are made possible only thanks to tools and the infrastructure to commit, test, and deliver changes within a very short timeframe. This is where Jenkins has emerged as the most promising candidate. In this blog post let’s discuss continuous integration with Jenkins.
What is Continuous Integration with Jenkins?
Jenkins is a Java-based cross-platform, continuous integration, and continuous delivery application that increases overall productivity. Jenkins can be used to build and test 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 providing powerful ways to define your build pipelines and integrating with a large number of testing and deployment technologies.
Jenkins is a continuous integration server. In simple words, continuous Integration is the practice of running your tests on a non-developer machine automatically everytime someone pushes new code into the source repository.
Features of Jenkins
1. Jenkins can be configured entirely from its friendly web GUI with extensive on-the-fly error checks and inline help.
2. Jenkins integrates with virtually every SCM or build tool that exists today.
3. Most parts of Jenkins can be extended and modified, and it’s easy to create new Jenkins plugins. This feature allows you to customize Jenkins to your needs.
4. Jenkins can distribute build/test loads to multiple computers with different operating systems.
The Present & Future of Continuous Delivery with Jenkins
The open source Jenkins platform is a leader in the continuous delivery space.
1. While it was released only in 2011, there are more than 85,000 active installations worldwide, many of which are being used as a hub for continuous delivery and the DevOps development methodology. Jenkins is every bit the future of continuous delivery.
2. The Jenkins community has developed about 1,000 plugins, enabling the software to integrate with many popular technologies.
3. Active Jenkins installations increased by 160 percent in 2013 and by more than 300 percent in the three years up till the end of 2015.
4. Continuous delivery not only involves high-frequency iterations to improve the way software works, but also allows real-time checks to measure whether code changes are achieving specific business objectives. With Jenkins, developers will have a way to provide direct feedback to the business. This will be one significant change in the corporate culture.
5. In a survey of 721 development professionals in San Francisco, it was revealed that all types of job profiles are interested in Jenkins, with developer being listed as the most common job role (71 percent), followed by build manager (41 percent), software architect (24 percent) and DevOps professional (21 percent).
