Trove taskmanager—A service that does the heavy lifting as far as provisioning instances, managing the lifecycle of instances, and performing operations on the database instance. Manager as the manager. The manager then redirects the handling to an object from the models. The actual handling is usually done in the models.


Trove guestagent—A service that runs within the guest instance, responsible for managing and performing operations on the database itself.

The benefit of such an improvement is that there would be only one interaction channel between the taskmanager, guestagent, and conductor—AMPQ. With the conductor, the guestagent would be able to write statuses to the Trove back-end through RPC.
