Renren’s Middle‑Layer Architecture: Design, Technologies, and Performance Optimizations

The article describes how Renren builds a high‑performance middle‑layer using open‑source components such as MySQL, Tokyo Cabinet/Tyrant, Nginx, Resin, Squid, LVS, Struts, Lucene, Netty, Ganglia, Memcached, and ICE to reduce database load, achieve sub‑20 ms response times, and support massive read/write traffic.
