Hi, communities

Please tell me about the connection status between "Appian RPA (Cloud)" and the Host Machine with "Appian RPA Agent" are installed.
When Appian Cloud instructs "RPA" processing from "Process", I think it's the flow of below,
    Cloud -----> Host Machine(Agent)
but how is this connection started in the first place?

---------------------------------------------
A) Just issue an order from the Cloud to the Host Machine
1. Session Start & RPA instructions
    Cloud -----> Host Machine(Agent)
---------------------------------------------
B) Agent initiates a session, and Cloud requests using that session
1. Session Start & stay connected
    Host Machine(Agent) -----> Cloud

2. RPA instructions
    Cloud -----> Host Machine(Agent)
---------------------------------------------
C) Other than those above

There is also a good description starting here about the agents behaviour.

thanks Randall

I understand as follows.
Cloud (Orchestration Server) holds what the agent should do
Agent is always asking Cloud (Orchestration Server) what to do
---> If there is an execution instruction, the Agent will get the necessary information and execute the instruction.

Therefore, communication is always performed from the Agent side. OK?

Yes,

The agent makes requests to the console, never the other way around. You can see the agent - orchestration server communication just like a user - browser - server interaction.
