Networking between the manager and agent can be initiated by either side:
The manager can send control instructions to agents, and agents return the execution results in response.
Agents can send to the manager requests to register themselves and DBMS instances as well as to update the state of instances. The manager, in turn, sends a response to the agents’ requests.
The manager and agent use the HTTPS protocol for communication.
By default, the manager uses the tcp/8080 port, and the agent
uses the tcp/8081 port. This traffic direction must be taken
into account when configuring network access rules. The address
and port are specified in the ppem-manager.yml manager
and ppem-agent.yml agent configuration files.
For secure data transfer, TLS configuration is recommended.
