A faster site for global users
What is a CDN?
Understand how a CDN delivers your site faster to users around the world and reduces origin server load.
What is a CDN and how does it speed up a site?
A CDN (Content Delivery Network) is a global network of edge servers that cache static content (images, CSS, JS, video) at locations closer to the user. A visitor from Germany gets content from Frankfurt in 20ms, instead of from an origin server in the US in 200ms. BeoHosting offers free Cloudflare integration, DDoS protection, SSL and HTTP/3. The result: a 2-5x faster site and better Core Web Vitals for SEO.

What is a CDN and why does it matter?
A CDN (Content Delivery Network) is a geographically distributed network of servers that delivers web content to users from the nearest location. Instead of every visitor pulling content from a single server (which may be thousands of kilometres away), a CDN keeps copies of your content on hundreds of servers around the world.
Think of a CDN as a network of delivery warehouses. If you have one warehouse in Belgrade, delivery to New York takes days. But if you have warehouses in every major city, delivery is same-day. A CDN does the same — it keeps copies of your site on "edge" servers near users for instant delivery.
Today every major site uses a CDN — from Netflix and YouTube to WordPress blogs. A CDN is especially important for sites with an international audience, but it also provides DDoS protection and SSL optimization for any site. BeoHosting recommends Cloudflare as a free CDN solution for all users.
How does a CDN work?
A CDN uses a network of edge servers that cache content near users. Here is what the request flow looks like:
A user opens the site
A user from New York types in your domain. DNS resolves the address and routes the request to the nearest CDN edge server (in this case a server in the eastern US) instead of to your origin server in Serbia.
The CDN checks the cache
The edge server checks whether it has a cached copy of the requested content. If it does (cache hit), it sends the content to the user immediately. If not (cache miss), it contacts the origin server.
Origin fetch (when needed)
On the first access, the CDN fetches the content from your origin server, stores it on the edge server and sends it to the user. Every subsequent user at that location gets the cached version.
Delivery from the edge server
The content is delivered from the edge server geographically closest to the user. Instead of 200ms of latency back to Serbia, the user gets a response in 20ms from the local CDN server.
The benefits of using a CDN
A CDN brings far more than just speed — it improves the security, reliability and SEO of your site.
Loading speed
A CDN reduces latency by delivering content from the nearest server. A site that loads in 3 seconds from Serbia can load in just a few tens of milliseconds for a global audience.
DDoS protection
CDN networks absorb large volumes of malicious traffic. Cloudflare, for example, blocks an average of 72 billion cyber threats per day across its global network.
Reduced server load
A CDN serves static files (images, CSS, JS) instead of your hosting server, reducing load by 60-80%. Your server only handles dynamic content.
SSL/TLS optimization
CDN providers offer free SSL certificates and optimize the TLS handshake for faster, more secure HTTPS connections with users.
Global availability
With a CDN, your site is equally fast for users in Belgrade, New York and Tokyo. Edge servers on every continent ensure a consistent experience.
Image optimization
Advanced CDN services automatically compress and convert images to modern formats (WebP, AVIF) and resize them for each device without losing quality.
Popular CDN providers
There are several CDN providers, each with its own strengths. Here are the most popular options:
Cloudflare (recommended)
The most popular CDN, with a free plan that includes CDN, DDoS protection, SSL, DNS and optimization. Over 300 locations worldwide. Ideal for most sites in the region.
