The shift toward intelligent routing like this is becoming essential, especially as more apps are global by design. What stands out here is the combination of hardware acceleration and CDN, most approaches lean heavily on just one. Using both seems like the right balance for latency and scalability.
Some dev teams like OpenForge.com have explored similar infrastructure challenges when building performance-focused apps at scale, would be interesting to see how these patterns evolve for edge-heavy or real-time workloads.
