Ask Your Proxy, It Knows Everything
summary
Proposes replacing app-level user/role, feature-flag and discovery logic with a smart edge proxy that enriches requests with identity and attribute headers, eliminates round‑trip DB calls and lets services do parallel writes; implements a global fleet + control‑plane API (Backplane) with hot edge caches and mutual TLS; enables request enrichment, proxy API driven updates and 1% canary traffic shaping, claims ~75% of typical DB tables become non‑value add and reports lower latency and simpler service code in practice.
