The folks at Evernote were kind enough to write up an overview of their architecture in a post titled Architectural Digest. Dave Engberg describes their approach to networking, sharding, user storage, search, and some other custom services.

This post isn't meant to be an end all to Drupal and CDNs, but rather just some insight into the way I have tackled this issue for the time being.
