CDN architecture

Types of CDN

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

Push CDN

Content send automatically to the CDN proxy servers from the origin server in the pull CDN, and then requested content is delivered to the user. Here, the pushed content is the website owner’s responsibility that the proxy servers will deliver upon the user’s requests. 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.
