Why this sizing

This Extra Small Consul deployment supports up to 500 registered services on a three-server control plane. The primary cost driver is the compute instances, totaling $0.04 monthly for three n2-standard-2 machines. This configuration explicitly disables high availability, meaning a single server failure will disrupt service.
