A Content Delivery Network (CDN) is a group of worldwide servers that cooperate to bring content closer to users in order to provide it to them more quickly. To decrease loading times and overloading on a single origin server, CDNs keep a copy of the material in Cache Servers or Edge Servers in point-of-presence (POP) locations close to end users. A CDN aids in content caching at the network edge, which enhances website speed in ways that traditional web hosting services struggle to. However, a CDN does not completely replace the necessity for web hosting. Without saving the complete recordings, CDNs can cache different types of content such as web pages, images, and live streaming by caching it in chunks. A Content Delivery Network is beneficial for websites or web apps with significant traffic volumes and lots of international consumers. Because websites are housed on a single server in a single place, users from all over the world will suffer longer loading times due to the higher latency in the network during transmission. A CDN enhances user experience by speeding up website loading. Reducing latency, or the delay in a website's response to a user request, is the main objective of a content delivery network (CDN). By spreading material across numerous servers managed by CDN providers all over the world as opposed to a single server to handle website traffic, CDNs assist in reducing latency. Customers can benefit from faster loading times via CDNs, and they can also stop website crashes in the event of a traffic surge. 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.

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.
