What are the best practices for using a Content Delivery Network (CDN) to reduce latency and improve website performance?

When deploying a Content Delivery Network (CDN) to reduce latency and improve website performance, core practices include resource optimization, node coverage, cache strategy adjustment, and real-time monitoring. Resource preprocessing: Compress static resources (such as images, CSS/JS) and enable Gzip/Brotli compression to reduce the amount of transmitted data; adopt chunked transfer for large files to adapt to different network environments. Node selection: Prioritize CDN providers that cover the main regions of target users, ensuring edge nodes are geographically close to users, especially for cross-regional or global users. Cache configuration: Set reasonable TTL (Time to Live) for static content (such as images, videos) to avoid frequent origin requests; enable edge computing or intelligent caching (such as session-based caching) for dynamic content. Real-time optimization: Monitor CDN node response time, cache hit rate, and origin request rate, adjust resource routing based on user access data, and avoid the impact of single points of failure. Cache strategies can be adjusted according to website traffic fluctuations, or resource distribution paths can be optimized through the CDN provider's intelligent load balancing function to continuously enhance user access experience.
