Load Balancing

Prerequisite: Familiarity with the concepts introduced in Executive Summary. Review it first if the terminology in this part is unfamiliar. Answer-first: Handling millions of requests per second (the C10M problem) requires eliminating kernel-space context switching overhead through asynchronous event loops (epoll/kqueue) or kernel-bypass networking (DPDK, io_uring), paired with zero-copy I/O memory buffers, L4 DSR (Direct Server Return) load balancing, and lock-free concurrency structures in Go. Deploying this pattern guarantees sub-50ms P99 latency bounds, zero-allocation memory pooling via Go 1.24 string interning,. ...

Prerequisite: Familiarity with the concepts introduced in Part 3 — Identity. Review it first if the terminology in this part is unfamiliar. Part 4 — MCP Gateway Architecture & Routing Answer-first: Operating multiple independent MCP servers across an enterprise creates point-to-point management sprawl and security leaks. An MCP Gateway acts as a centralized reverse proxy control plane, handling dynamic tool routing, rate limiting, authentication enforcement, and circuit breaking for all downstream MCP server microservices. Architecting this pipeline enforces sub-50ms P99 latency guarantees, OpenTelemetry GenAI semantic conventions, and 2026 Model Context Protocol. ...
