Sisällönjakoverkot

Sisällönjakoverkot, or Content Delivery Networks (CDNs), are geographically distributed networks 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 serve as a cache for web content, storing copies of static files such as images, CSS, and JavaScript on servers located closer to users. When a user requests content, it is delivered from the nearest CDN server, reducing latency and speeding up load times.

CDNs are crucial for websites and applications that experience high traffic or serve a global audience. By offloading traffic from the origin server, CDNs can significantly improve website performance, reduce bandwidth costs, and enhance user experience. They are also vital for ensuring the availability of content during traffic spikes or network congestion. Many major online services, including streaming platforms, e-commerce sites, and social media networks, rely heavily on CDNs to deliver their content efficiently and reliably. The infrastructure involves a complex system of interconnected servers managed to optimize delivery routes and ensure data integrity.
