What is Push Content Delivery Network and Pull Content Delivery Network?

Push Content Delivery Network sends material from a website's origin server to edge servers (PoPs) all across the world on a regular basis. An edge server duplicate of the website is used to serve visitors. It operates in a similar manner as a prefetch. Push CDN works best for static, infrequently changing files and low-traffic websites.


Pull Content Delivery Network- Before a user requests a resource for the first time, Content Delivery Network, also referred to as Reverse Proxy, does not store the contents of the website on CDN Edge Servers. The Edge server contacts the origin server when a user requests content and requests a copy to deliver to the user. The Edge server's cache will be used to fulfil any pending requests for that content. Smaller files like images, javascript, and so forth are best suited for it.


A Content Delivery Network (CDN) is a network of servers that enables the distribution of content from a "origin" server, where it is initially hosted, through proxy servers that take client requests and route them to other edge servers spread out over the globe. A CDN's edge servers can either be Points of Presence (PoP) with a single server or data centres with numerous servers. These are deftly positioned at a variety of locations, where the content is cached before being supplied via CDN


Caching is the practise of copying data from an origin server and storing it on edge servers. By moving edge servers closer to users, it aids the origin server in decreasing traffic burden on a website, which decreases loading times since less distance must be travelled to reach the user. Internet exchange points (IXPs), which link different internet service providers to exchange traffic, are typically close to where Content Delivery Network Edge servers are situated. By placing servers in these connected places, CDN companies can save time and money.
