I am delighted to write this inaugural post for "GO Behind the Scenes" -- our Dev column in the new Globus Online (GO) blog. Entries could come from any member of the GO development team. We're looking to provide a small window into what we do to make GO ..er..uh.. go! This one comes from Stuart Martin, the GO software development manager for the backend. (The backend is the engine that takes the file transfer requests and moves the bytes from point A to point B.) Since we like to plan big, we run all of GO on Amazon's EC2. This way, when the time comes, we will be able to run instances worldwide.
