publish the modified request to a request topic of the communication connection, wherein the communication connection comprises a plurality of topics, each of the plurality of topics configured to send or receive information of a particular type.

13 . The non-transitory, computer-readable media of claim 12 , wherein the instructions further cause the processor to modify the response using the extracted identifier; and

route, based on the extracted identifier, the modified response to the process.

14 . The non-transitory, computer-readable media of claim 11 , wherein the instructions further cause the processor to subscribe the agent to one or more topics of the communication connection for receiving commands from the control plane and sending requests to the control plane.
