Content Delivery Network - CDN

Giriş

Açıklaması şöyle. CDN sık kullanılan şeyleri cache'ler

A CDN is a network of servers that are distributed around the world, and are used to deliver content to users based on their location.

When a user requests content from a CDN, the closest server to the user will deliver the content, rather than having the user’s request be routed to the origin server. The content is then cached on the CDN server, so that if another user in the same location requests the same content, it can be quickly delivered from the cache.

Açıklaması şöyle. Cache'lenen şey herhangi bir şey olabilir. 

They allow websites to cache frequently accessed assets — such as pictures, videos, or JavaScript files — to make the website more performant and avoid downtime.

1. Push CDN: You are responsible to upload data to the CDN servers

2. Pull CDN: The CDN will pull data from your servers (origin servers)
