Sisällönjakeluverkko

Sisällönjakeluverkko, often abbreviated 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 typically used for delivering media content, such as images, videos, and audio files, as well as web pages and software downloads.

When a user requests content that is part of a CDN, the request is routed to the server geographically closest to the user. This reduces latency and speeds up the delivery of content. CDNs can also help reduce the load on the origin server by caching content and serving it from multiple edge locations. This improves website performance and user experience.

The implementation of a CDN involves a network of servers strategically placed around the world. These servers store copies of the website's or application's content. When a user accesses the content, the CDN directs their request to the nearest server, which then delivers the cached content. This distributed approach ensures that content is delivered quickly and reliably, regardless of the user's location or network conditions.

CDNs play a crucial role in the modern internet infrastructure, enabling faster loading times, improved reliability, and better scalability for online services. They are essential for businesses that rely on delivering digital content to a global audience.
