Why this sizing
OpenSearch at the extra small tier maps to the single-node reference architecture on AWS in us-east-1. Compute is the largest line item in this estimate, accounting for 76% 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.
