After the CI steps have completed successfully, you will have shiny new artifacts that are ready to be deployed to servers. Usually, these are test environments set up to behave like production servers. We will discuss deployment system alternatives later in the book.
Often, the last thing a build server does is to deploy the final artifacts from the successful build to an artifact repository. From there, the deployment servers take over the responsibility of deploying them to the application servers. In the Java world, the Nexus repository manager is fairly common. It has support for other formats besides the Java formats, such as JavaScript artifacts and Yum channels for RPMs. Nexus also supports the Docker Registry API now.
Using Nexus for RPM distributions is just one option. You can build Yum channels with a shell script fairly easily.
