Hosting on A CDN Server
The CDN network of servers is used to host and serve static data. Static Data is the most requested data nowadays which your hard working web server sends to your users. These static items within a website include CSS files, videos, images, audio clips and Java scripts. Serving this data at every new browser request takes precious resources from your server which could be used in serving your content from the database.
High-capacity Service of CDN Networks
A single web server can process so many requests but cannot scale infinitely. When a single server of your site overloads, you have to add another server and coordinate data synchronization between the two servers and you need to implement load-balancing to service more requests. This enhances the technical burden of running your business and also consumes your precious time. Whereas a CDN network can automatically distribute the load across all of its servers for you. You just need to tell it what data you want it to serve.
Distributed Infrastructure of CDN
CDN network has a highly distributed service platform with servers located on networks and small and large data centers. It helps to provide unparalleled performance for your users. Its distributed infrastructure also provides the facility of fault tolerance. When many servers in the CDN network actually go down then also your website would remain unaffected. Traffic is simply routed to the next nearest CDN server.
Analytics of CDN
