Answer 1

Are you meaning Content distribution network (like Akamai) when you say CDN? If so, then the answer is "it depends."

It depends on which service you use: Each service has different capabilities. Akamai has a full API that you can do all kinds of fun stuff with. Some only do geographical DNS tricks with servers on the east & west coast. Some are in between.

It also depends on what you want to use the service for. Just image hosting? File downloads? Streaming content?

The easiest is probably to make sure that static assets (images, javascript and CSS, usually) is easily cachable, and movable. We've done this using a special template function that takes a relative URL (something like /images/graphics/someimage.png) and turns it into a link to our static server (http://static.example.com/images/graphics/someimage.png).

When you have a function that does this, and use it to generate all static asset URLs, it will be trivial later on to move these assets to a different server, or even to different servers based on geolocation.
