Jenkins Concepts

• Jenkins: An open-source automation server used for continuous building, testing, and deploying software with the help of plugins.
• Poll SCM: A feature in Jenkins that periodically checks the version control system for changes.
• Cron: Cron is a time-based job scheduler in Unix-like operating systems to schedule and automate the execution of jobs periodically at fixed times or specific intervals.
• Version Control System (VCS): A software tool that helps manage and track changes to source code, documents, and other files in a collaborative environment. Example: Git.
• Build: The process of converting source code into an executable or deployable form.

Jenkins is an open-source automation server, that allows us to automate the software development process through continuous integration, continuous testing, and continuous deployment/delivery with seamless integration of different plugins like git, maven, sonar qube, frog, tomcat, etc…One such crucial feature is the Poll SCM (Source Code Management) option, enabling Jenkins to periodically check your version control system for changes and trigger builds accordingly. Which mainly helps Developers or DevOps engineers integrate their newly developed code into the CI pipeline.
