Why this sizing

This Extra Small OpenSearch configuration supports up to 100 GB of hot index data on a single node. The primary cost driver is compute, accounting for $196 monthly, significantly more than the $95 for storage. This single-node setup lacks high availability, making it unsuitable for production workloads requiring fault tolerance.
