Rule 2: Use a Content Delivery Network(Chapter 2 of High performance Web Sites)
A content delivery network (CDN) is a collection of web servers distributed across
multiple locations to deliver content to users more efficiently.This efficiency is typically
discussed as a performance issue, but it can also result in cost savings.When
optimizing for performance, the server selected for delivering content to a specific
user is based on a measure of network proximity.For example, the CDN may choose
the server with the fewest network hops or the server with the quickest response
time.
