While the ReplicaSet controller manages the scale of the ReplicaSet, the Deployment controller manages what happens to the ReplicaSet – whether an update has to be rolled out, or rolled back, etc. When Deployments are scaled up or down, this results in the declaration of the ReplicaSet changing, and this change in the declared state is ...

Updates are offered either as RPM packages or as complete disk images that can be deployed as needed. Using RPM allows adding custom packages to a base Azure Linux image to support additional features and services as needed.

Reliable releases: The risks associated with a release have significantly decreased, and the release process has become more reliable. With continuous delivery, the deployment process and scripts are tested repeatedly before deployment to production. So, most errors in the deployment process and scripts have already been discovered.
Continuous deployment (CD) is a software engineering approach in which software functionalities are delivered frequently and through automated deployments. [1] [2] [3]
