Why Do We Need CDN?
Remember? When you were trying to open your favorite E-commerce site, you waited for it to load, but the only thing loaded was the onscreen content. It is called latency – the delay that occurs when you want a web page to load but you see its content instead. The delay is technically the distance between the user and the hosting server. Consequently, CDN efficiently functions to abandon the annoying effect of latency.
What Are the Goals of CDN?
The utmost goal of Content Delivery Network is to curtail the physical difference of the delay via VI. Besides minimizing the latency effect, it also intensifies the swiftness and performance of a web page.
How Does It Work?
CDN keeps every itsy-bitsy component detail of the internet in a nutshell. Most importantly, it stores cached versions of every snapshotted page to index the content and other databases. These caches of web pages help in diminishing the delay by storing this version in a variety of geographical locations, these locations are known as a Point of Presence/PoP.
Every PoP contains multiple cached versions/servers that are assigned to deliver content in its relevant proximity. CDN is an excellent source to deliver tremendous coverage for several geolocations and places worldwide. For instance, you can watch a vibrant live streaming of Apple’s product happening in California sitting comfortably on your sofa without moving to another place. This is the power of CDN that brings quality and speed at a peak of time.
Who Uses it?
Almost half of the worldwide traffic is a user of CDN. Professionally, the large-scale corporations that deliver massive information to its global audience, get the assistance of CDN on a general basis.
