Jenkins is an **open-source automation server** that can complete any task given to it in an automated way provided all the plugins are installed on it to complete that task.

Jenkins can :

1. Build and test your code
    
2. Deploy your application
    
3. Integrate with other tools and systems to use their functionality
    
4. Automate repetitive tasks such as backups, database migrations, and server maintenance.
    
5. Monitor the health of your system by running periodic checks.
