Why this sizing

Keycloak at the extra small tier maps to the single-node-small reference architecture on Azure in eastus. Compute is the largest line item in this estimate, accounting for 86% of monthly cost. High availability is not included here, so this baseline stays lean and leaves failover headroom out of the monthly total. Keycloak carries the heaviest storage footprint at 100 GB.
