Ctrip Service Mesh Performance Optimization and Practices
This article details Ctrip's large‑scale Service Mesh deployment using Istio, analyzes control‑plane performance bottlenecks such as pilot concurrency and configuration push latency, and presents a series of optimizations—including namespace isolation, concurrent ServiceEntry processing, incremental EnvoyFilter handling, and pilot configuration tweaks—that dramatically improve init‑context and push times while supporting thousands of services.
