CDN (Content Delivery Network).
A CDN is a global network of servers that delivers your website files as close to the user as possible. Instead of all visitors accessing a single server in Zurich, the CDN delivers content from the nearest data center — for maximum loading speed.
CDN (Content Delivery Network) — Explained in Detail
A CDN (Content Delivery Network) is a global network of servers that delivers static website resources — images, CSS, JavaScript, videos — as close to the user as possible. Without a CDN, every visitor to your website loads all content from the same server (e.g., in Zurich). With a CDN, a data center in Frankfurt, London, or New York delivers this content — depending on where the visitor is located. This reduces latency and dramatically improves loading time.
CDNs are essential for good Core Web Vitals: They reduce TTFB (Time to First Byte), improve LCP (Largest Contentful Paint), and ensure consistent performance worldwide. Leading CDN providers are Cloudflare (with a free basic plan), AWS CloudFront, Fastly, and Vercel Edge Network. Many modern hosting solutions like Vercel or Netlify integrate CDN automatically.
For Swiss companies, a CDN is particularly important when you target international customers or your server is located in Switzerland (where hosting is expensive). DLM Digital configures a CDN setup for all projects by default — typically Cloudflare for DNS and edge caching, combined with Vercel for serverless deployments. The result: equally fast loading times from Zurich, Geneva, London, or New York.

For most SME websites, a CDN is recommended but not strictly necessary if your target audience is exclusively in Switzerland. From the moment you have international visitors or are aiming for better PageSpeed scores, a CDN makes sense. Cloudflare offers a free plan that is sufficient for most SME websites.
Web hosting is the server where your website files are stored. The CDN is a network of proxy servers that caches and delivers these files worldwide. Both complement each other: hosting for the main source, CDN for fast global delivery.
For most projects, we use Cloudflare (free for basic protection and CDN, cost-effective for pro features) combined with Vercel Edge Network. Cloudflare additionally offers DDoS protection, Web Application Firewall, and automatic HTTPS certificates.
