A content delivery network (CDN) refers to clustered servers distributed around the world to ease availability and high performance. The following are some uses of Rackspace CDN:
Commonly built with a mix of static objects and text, formatting like CSS, and some media components like marketing videos, websites can be CDN enabled quickly and easily. With origin-pull technology, you simply
identify a hostname and an origin and your entire site is cached and accelerated.
Applications often have cacheable components, like pictures, static text, and style formatting, that can be cached on the edge node. For dynamic, non-cacheable content, Rackspace CDN finds the best route back to the origin and prefetches upcoming material to improve delivery speeds.
Instead of having your web servers render content for every unique visit, you can use a CDN to deliver cached content to website visitors instead. This reduces the load on your local web server and database because HTML is served near the user's location. Apart from this CPU efficiency, users also get content faster because the latency has improved.
For eCommerce stores with a variety of photos and static assets, rendering product pages can involve paying for a large amount of outgoing bandwidth. If your eCommerce platform displays images dynamically (for custom dimensions, for example), this gets even more expensive. Rackspace CDN enables you to selectively cache certain subdomains or URL patterns to edge nodes. Users get content from the edge node rather than your web servers.
