CDN design

Content caching strategies in CDN

Which content has to cache is an important matter for an organization to deliver up-to-date web content. There are two classifications of CDN used to get the content from the origin servers.

Push CDN

Content sends automatically to the CDN proxy servers from the origin server in the pull CDN, and then requested content is delivered to the user. The content delivery to the CDN proxy servers is the content provider’s responsibility. The content is pushed to proxy servers located in various locations according to the content’s popularity. The one problem with the push approach is that if content updates frequently and the origin server serves other heavy traffic, this frequent sync will create more trouble.
