概要
This skill provides comprehensive guidance on building and maintaining high-performance systems capable of handling thousands of concurrent users. It empowers developers to implement critical optimization patterns such as distributed caching with Redis, horizontal and vertical scaling, and robust application performance monitoring (APM). By integrating these methodologies, users can effectively identify system bottlenecks through profiling and architect resilient, low-latency infrastructures using modern tools like Nginx, Datadog, and OpenTelemetry.
