CI Server periodically or on every change, will grab the source files from version control system and
attempts to build the product (compile/test/package). If build process is successful, it means changes
have been integrated successfully.
Continuous Delivery(CD)
Is a service, which focuses on automated testing and deployment capabilities allowing high-quality
software to be developed and deployed rapidly, reliably and repeatedly with minimal manual
intervention.
Continuous Deployment(CD)
Is a practice in which every code change goes through the entire pipeline and is put into production,
automatically, resulting in many production deployments every day.
