Introduction to Jenkins
In the fast-paced world of software development, delivering high-quality applications quickly is crucial. This is where Jenkins, the leading open-source automation server, comes into play. Jenkins is a powerful tool that helps developers automate the building, testing, and deployment of software, making it an essential part of any DevOps pipeline.
Jenkins is widely recognized for its flexibility, extensibility, and robust community support. Whether you’re a small startup or a large enterprise, Jenkins can be tailored to meet your specific needs, making it a go-to solution for Continuous Integration and Continuous Delivery (CI/CD).
What is Jenkins?
Jenkins is an open-source automation server that enables developers to automate the various stages of the software development lifecycle. It was originally developed as the Hudson project in 2004 and later forked into Jenkins in 2011. Since then, Jenkins has grown into one of the most popular CI/CD tools in the industry.
