Sisältöjakeluverkostot

Sisältöjakeluverkostot, or Content Delivery Networks (CDNs), are geographically distributed groups of servers that work together to provide fast delivery of internet content. When a user requests content, such as a webpage, image, or video, from a website that uses a CDN, the request is routed to the server closest to the user's location. This proximity significantly reduces latency and speeds up content loading times.

CDNs store cached copies of website content on their edge servers, which are located in various data centers around the world. By serving content from these nearby servers, CDNs alleviate the burden on the origin server, improving its performance and reducing the risk of overload. This is particularly crucial for websites with a global audience or those experiencing high traffic volumes.

The benefits of using a CDN extend beyond just speed. They enhance website reliability and availability by distributing traffic across multiple servers. If one server goes down, others can take over, ensuring continuous access to content. CDNs also contribute to improved security by offering features like distributed denial-of-service (DDoS) attack mitigation. Ultimately, CDNs are an essential component for modern web infrastructure, optimizing user experience and website performance.
