Couchbase Server Enterprise at the extra small tier maps to the combined-services-small reference architecture on Google Cloud in us-central1. Compute is the largest line item in this estimate, accounting for 70% of monthly cost. High availability is not included here, so this baseline stays lean and leaves failover headroom out of the monthly total. Cluster Node carries the heaviest storage footprint at 500 GB on each of its 3 nodes.
