This Extra Small tier provisions three n2-standard-4 instances, each with 4 vCPU, 16 GB RAM, and 500 GB SSD, to support up to 1 TB of replicated OLTP data. Compute is the primary cost driver at $587 monthly, significantly more than the $255 allocated for storage. A key consideration for this three-node setup
