Why this sizing

This Extra Small tier supports up to a 250 GB database for light OLTP workloads on a single primary instance. The primary cost driver is the n2-standard-4 compute instance, which provides 4 vCPUs and 16 GB RAM. A key tradeoff is the absence of high availability, meaning no automatic failover in case of instance failure. The n2-standard-2 instance is likely for a management or utility function, given its smaller size and minimal cost contribution.
