Size OpenSearch on Google Cloud

Extra Small — up to 100 GB hot index data on a single node

Monthly cost

$290.64

Annual cost

$3,488/year

Line-item breakdown

Compute $195.64
Storage $95.00
Other $0.00

Components provisioned

Role Instance vCPU GB RAM Storage
Node 1 × n2-standard-4 4 16 500 GB

Why this sizing

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.
