Regional CDN node
Workload: One node serving a city, country, or ISP-heavy audience from cached content.
Sizing: Cache hit ratio and storage size decide whether traffic is mostly outbound or also origin-heavy.
Fit: 20 Gbps gives meaningful headroom without moving into a large 40 Gbps footprint.
Limit: If cache misses are frequent, origin capacity matters as much as edge capacity.
