Do we need to create Agents on each Target server for release and Deployments.

Hi,
We do have Stage, Release and Production three node cluster environment. We tried to create build and deploy the code to Stage by creating Agents on target server with out issues. But Do we need to create Agent on all target servers or can we  use single Agent for all the servers.

You need to install an agent on any machine where you're either creating images (either directly from a database on the instance, or with a temporary instance you're using to create images from backup) or creating clone databases derived from those images. This is because SQL Clone uses disk-based virtualization technology and so needs to be able to create and mount virtual hard disks (and use the Volume Shadow Copy Service to create images from live databases). So if you want to create clones on machines in your Release environment then you'll need to install agents there. You only need one SQL Clone Server, though - this is the central coordination server from which the agents are controlled.

Note that SQL Clone doesn't create images or clones using clustered instances (although you can create images from a backup taken from a cluster using another instance), and that we wouldn't recommend using clone databases for production.
