CDN configuration

CDN configuration aligns edge delivery with your application architecture to accelerate static assets, improve resilience, and keep costs predictable. The process starts with vendor selection based on footprint, performance SLAs, and feature set (HTTP/2 and HTTP/3, TLS 1.3, Brotli/Gzip compression, image optimization, and edge compute). Caching policies are tuned with precise cache keys, TTLs, and rules for HTML, APIs, static resources, and third-party scripts; content-hashing enables long-lived caching without staleness, while cache-busting and automated invalidations keep releases safe. Tiered caching and origin shielding reduce load on Salesforce origins and any auxiliary backends, and “stale-while-revalidate” preserves snappy responses during re-fetches. For media-heavy experiences, on-the-fly image resizing, format negotiation (WebP/AVIF), and adaptive bitrate for video cut payloads dramatically. Edge routing, geo-load balancing, and smart prefetch/preconnect directives minimize latency globally, and granular rules ensure sensitive endpoints bypass cache. Security is built in with WAF, DDoS protection, bot management, signed URLs/tokens, strict CSP and CORS controls, and HSTS; logs and real-time analytics feed monitoring and alerting pipelines for quick remediation. Integration patterns respect Salesforce constraints (Static Resources, Experience Cloud sites, and LWC asset loading), SPA nuances (service worker coordination and route caching), and third-party dependencies. Finally, continuous testing with RUM/Lighthouse, synthetic checks, and performance budgets validates improvements, while cost controls—tiered pricing, cache hit targets, and controlled purge strategies—keep the solution efficient as traffic scales.
