DevOps brings along a new concept of CI/CD that represents Continuous Integration, Continuous Delivery, and Continuous Deployment.
Continuous Integration aims at collaborating the work of individual developers into a single repository to minimize the friction points in the deployment processes.
Continuous Delivery extends Continuous Integration and is the automation of the software delivery process that enables easy deployment into production- at any point in time.
Continuous Deployment is an extension to Continuous Delivery, and it automates deployment on the successful accomplishment of all the tests.
