OpenSearch at the extra small tier maps to the single-node reference architecture on Google Cloud in us-central1. Compute is the largest line item in this estimate, accounting for 67% of monthly cost. High availability is not included here, so this baseline stays lean and leaves failover headroom out of the monthly total. Node carries the heaviest storage footprint at 500 GB.
