Understanding CDNs

Let's Explore How Content Delivery Networks Work

A CDN, or Content Delivery Network, is a distributed network of servers strategically located around the world to efficiently deliver web content to users based on their geographic location.

Here's how a CDN works

Server Distribution

A CDN consists of multiple servers, often referred to as edge servers or nodes, strategically positioned in various geographical locations.

Content Replication

The CDN caches or replicates static content across its network of servers. When a user requests a particular piece of content, the CDN delivers it from the server closest to the user, reducing latency and load times.

Load Balancing

CDNs often employ load balancing algorithms to distribute traffic efficiently among their servers. This ensures that no single server is overwhelmed with too many requests.

Content Delivery

The selected server (edge server) delivers the requested content to the user. This proximity minimizes the physical distance between the user and the server, reducing latency and optimizing load times.
