Content Delivery Networks deliver content from edge nodes geographically close to users, eliminating the latency of round-trips to a distant origin server. For a website hosted in Germany serving Greek users, Cloudflare’s Athens PoP (or nearby) delivers static assets in under 5ms rather than the 30-50ms round-trip to the origin. Hellenic Technologies integrates CDN services into every client stack and configures them to maximise cache efficiency and edge delivery. Static asset delivery is the baseline use case: CSS, JavaScript, fonts, and images should always be served from CDN with long cache TTLs. We configure cache-busting via content hashes in filenames (the standard behaviour in Vite, webpack, and Next.js) so assets can be cached forever at the edge while new deploys immediately serve updated files. This achieves both maximum cache efficiency and instant cache invalidation without maintaining complex purge logic. Image optimisation is an often-overlooked CDN capability. Cloudflare Images and Cloudflare Polish automatically compress and convert images to WebP for supporting browsers, reducing image payload by 20-40% without quality loss. For applications using cloud storage (S3, GCS), we configure signed URL CDN delivery that caches protected content at the edge without exposing storage credentials or generating S3 egress costs per request. CDN performance services:
  • Cloudflare CDN configuration with optimised cache rules per content type
  • Static asset pipeline integration: cache-busting hashes and long TTLs
  • Image optimisation: WebP conversion, compression, and responsive images
  • Cloudflare Polish and Mirage configuration for automatic image optimisation
  • S3/GCS CDN delivery with signed URLs and origin shielding
  • Edge caching for API responses with appropriate Vary headers
  • CDN performance reporting: bandwidth saved, cache hit ratio, edge latency
  • Multi-CDN failover configuration for Enterprise-grade availability
  • Streaming media delivery optimisation for video and audio content
  • CDN cost analysis and optimisation recommendations
