Abstract

Gateway Domain-Centric Routing (GDCR) introduces a new architectural paradigm for enterprise API governance: domain-aligned, metadata-driven, vendor-agnostic routing at scale. Instead of proliferating vendor-specific proxies and tightly coupled gateway configurations, GDCR redefines the control plane by externalizing routing intelligence into deterministic metadata structures. The framework consolidates integration sprawl into semantic domain façades, enforces architectural boundaries at runtime, and guarantees traceability through immutable integration identities. Validated across SAP BTP Integration Suite, Azure API Management, AWS API Gateway, and Kong, GDCR proves cross-platform portability, deterministic routing behavior, and high-volume execution stability. Version 6. 0 — The Foundation — establishes the core architectural patterns, governance principles, routing logic, and multi-platform validation evidence that define GDCR as a portable, scalable model for modern enterprise API ecosystems. A dedicated slide deck is included to provide structured guidance for architectural adoption, implementation strategy, and executive-level presentation.
