Gateway Domain-Centric Routing (GDCR) : The Foundation - Version v6.0

Building Metadata-Driven Domain-Centric Routing for API Gateways Modern API integration landscapes often end up fragmented: proxy-per-backend systems exploding configuration artifacts frequent redeploys for every service change tight coupling between routing logic and vendor platforms What if instead of continuously rebuilding proxy layers, we treat routing as a governance layer orchestrated by metadata and domain semantics? In a recent independent research effort, I explored an architectural model called Gateway Domain-Centric Routing (GDCR) — a vendor-neutral, metadata-driven approach that separates: ✅ Immutable execution plane (proxies + routing engine) ✅ Mutable control plane (metadata + routing definitions) The core idea is that when new backends or vendors are introduced, the system doesn’t require modifying the routing proxies or redeployment. Instead, the routing engine reads updated metadata and resolves requests according to business domain semantics. This model was validated
