Scalability
From KallestadWiki
Web site performance is in large part based on the geographic friendliness of the client machine.
Latency in request times can make a site hard to view from all the way across the world, especially if a large number of requests are made to load a given page. Performance concerns can in part be alleviated by using cache control. Another option is to geographically disperse content amongst several geographically friendly data centers. For instance, you might have 8 data centers spread throughout the U.S. all containing roughly the same information. This is easy for static files, but an entirely different problem for data centric applications.
