Design and Implementation of a Multi‑Layer Load‑Balancing Platform (VGW)

This article explains how to build a reliable, high‑performance load‑balancing platform by analyzing basic reliability requirements, introducing multi‑layer (DNS, L4, L7) balancing, comparing Direct‑Route, Tunnel and FULLNAT modes, and describing the VGW architecture, health‑check, fault isolation, redundancy and DPDK‑based performance optimizations.

Design and Implementation of a Multi‑Layer Load Balancing Platform (VGW)

The article details how a multi‑layer load‑balancing platform (VGW) was designed—combining 7‑layer Nginx, 4‑layer LVS with FULLNAT, and 3‑layer network devices—to achieve business reliability, fault isolation via BGP‑announced VIPs, and high‑throughput performance using DPDK, while providing redundancy at server, link, and cluster levels.
