What Can CDN Caching Do For You?

[[email protected]]

The distribution of POPs will vary from CDN to CDN. Some providers prefer to cover more space with small capacity servers, while other CDNs aim to maintain a smaller number of high capacity POPs. An important thing to consider when analyzing a CDN’s architecture is figuring out where its POPs are located. Depending on where a particular website’s visitors are coming from, this can be a determining factor.

Content Types
Most of all website content consists of pre-formatted malaysia phone number library static files that are not expected to change over time (or for different users). These files are the default candidates for caching, unlike dynamic files that are generated on the fly based on information in a database.

When analyzing the global population’s internet usage, the content types that consume the most bandwidth are images, videos, and audio files. However, there are many other types of content that a CDN can serve. The supported content types and formats will vary for each CDN provider:


Reduces bandwidth costs.
Delivering content through CDN caching proxies offloads the origin (back-end) server and significantly reduces the bandwidth costs associated with serving content to a large number of visitors. For most sites, bandwidth costs can be reduced by 40% to 80%, depending on the percentage of cacheable content. Bandwidth consumption costs for website hosting are a primary expense for websites. Through caching and other optimizations, CDNs can reduce the amount of data an origin server must provide, thus reducing hosting costs for website owners.



Improves user experience.
A globally distributed network of caching proxy servers, CDNs bring your website content closer to all visitors, no matter where they are. Serving this content from a local server significantly increases access speed and user experience.
