CDN

Question 1

What is CDN

Answer 1

A content delivery network (CDN) is a geographically distributed group of servers that caches content close to end users.

A CDN allows for the quick transfer of assets needed for loading Internet content, including HTML pages, JavaScript files, stylesheets, images, and videos.

Question 2

What are 3 problems a CDN customer is facing?

Answer 2

Traffic Load:
Too much traffic can overload the origin server - impacting availability.

Poor UX:
Latency for end-users becomes proportional to the distance between the client and origin server.
CF’s CDN exists on the edge to reduce distance ergo latency.

Expensive:
More traffic means higher bandwidth, egress, and compute costs. CF does not charge egress fees - one set price regardless of traffic.
