MCP Gateway Architecture: Intelligent Dynamic Routing, SSE Multiplexing & Resiliency

Answer-first: MCP Gateway architecture solves N×M connectivity fragmentation by decoupling AI agent clients from distributed tool providers through persistent SSE connection multiplexing, Redis Token Bucket rate limiting, and dynamic tool schema routing. In production, a Go-based gateway delivers sub-4ms P99 proxy latency while protecting downstream backends with distributed circuit breakers and centralized OAuth 2.1 token introspection. ← Part 3: Identity & AuthN | Next Chapter: Part 5: Production Security & OWASP MCP Top 10 → ...

System Design Survival: The Architectural Shield Guide

📖 Bản tiếng Việt (Vietnamese Edition) Prerequisite: Familiarity with the concepts introduced in Part 6 — From Coder To Orchestrator. Review it first if the terminology in this part is unfamiliar. Answer-first: While AI assistants excel at generating localized code functions, they remain blind to holistic distributed system failures, network partition handling, and cascading degradation. System design—encompassing Circuit Breakers, Rate Limiters, Distributed Locks, and CAP theorem trade-offs—serves as the ultimate career survival shield for software engineers. Mastering distributed resilience primitives—Circuit Breakers, Sliding-Window Rate Limiters, Distributed Mutexes, and CAP theorem consistency boundaries—protects production platforms against probabilistic AI hallucination failures. ...
