Answer
Yes — IFS publishes a Server Sizing Guide for IFS Cloud that covers base and middle-tier server sizing considerations for an on-premise deployment used with the Aurena client (built around an on-premise Rancher cluster setup). It's explicitly labeled as informational only (not a contractual commitment), and its baseline scenario assumes a single-node Rancher cluster with manual configuration changes and only the necessary containers deployed — actual sizing for a customer-owned cloud environment (like Azure) should be discussed with IFS directly, since the guide's baseline scenario is specifically about on-premise hosting rather than a customer-managed cloud deployment.
