CDN - Content Delivery Network
A network of computers interconnected via the Internet to make data more accessible to users worldwide.
A Content Delivery Network (CDN) is a system of servers that delivers web content quickly to users based on their geographic location. Another name for CDN is Content Distribution Network. It’s basically a network that stores and delivers web content like images, videos, and scripts.
Individual CDN nodes are typically connected to a fast Internet backbone. Their number varies according to the chosen architecture and can reach up to several thousand nodes with tens of thousands of servers. Optimization through CDN results in lower hosting prices, faster sites, and increased resilience against traffic bursts on the served site.
Such a network consists of the following:
- A source server that provides the content to the CDN.
- Elements located in different parts of the Internet infrastructure where the content is replicated
- A routing system that ensures that content is delivered to the user from the geographically closest node in the network
CDNs reduce latency and improve website performance by caching content across multiple data centers worldwide. They also help balance traffic, handle large amounts of data, and protect against cyberattacks like DDoS. Common examples include services like Cloudflare, Akamai, and Amazon CloudFront.
Key points about CDNs: #️⃣
- Speed up website loading by reducing server response time.

- Reduce server load and prevent website crashes during traffic spikes.
- Offer protection against cyber threats like DDoS attacks.
- Commonly used by websites, apps, and streaming platforms.
