indholdsdistributionnetværk

Indholdsdistributionnetværk, often referred to as CDN, is a geographically distributed network of proxy servers and their data centers. The goal of a CDN is to provide high availability and performance by distributing the service spatially relative to end-users. CDNs are a form of distributed system that supports the distributed caching of content, such as web pages, images, and videos, close to users to reduce latency and improve loading times.

When a user requests content, the CDN directs the request to the server that is closest to them. This proximity reduces the physical distance the data has to travel, resulting in faster delivery. Without a CDN, all content requests would be sent to the origin server, which can become a bottleneck, especially during periods of high traffic. CDNs help alleviate this by offloading traffic from the origin server and distributing it across multiple edge servers.

Key benefits of using an indholdsdistributionnetværk include improved website speed, increased reliability, enhanced security through distributed denial-of-service (DDoS) mitigation, and better scalability to handle traffic surges. They are widely used by websites, streaming services, and online gaming platforms to deliver content efficiently to a global audience. The infrastructure of a CDN typically involves a vast network of servers strategically placed in various locations around the world, forming a robust and resilient system for content delivery.
