If your agents connect to the server through an agent relay, you must configure your networks and firewalls to allow the following communication. In this case, you install the agent relay on the same network and the same side of the firewall as the agents.

For example, if your server is on an internal network and your agents are on an external network such as a public cloud, you install the agent relay on the cloud and have the agents connect to the agent relay. Then, the agent relay connects through the firewall to the internal network.

If your agents connect directly to the server, you must configure your networks and firewalls to allow the following communication:

The blueprint design server must meet the following requirements:

The Heat orchestration engine must meet the following requirements:

The blueprint designer is compatible with the following cloud systems:

You must configure virtual images in supported clouds for communication with HCL Launch:
