Author here. Thanks for sharing these thoughts. You’re right that DSR, ASN-based routing, SRV records, and other lower-layer approaches are important in certain setups.

This post is focused primarily on Layer 7 load balancing, connection and request routing based on application-level information, so it doesn’t go into Layer 3/4 techniques like DSR or network-level optimizations. Those are certainly worth covering in a broader series that spans the full stack.
