Google App Engine is a scalable low-cost Platform as a Service run on Google's infrastructure. You get to use their toys (Datastore based on BigTable, large network of servers and datacenters, etc), but it will not "just work" with most Django/Python web applications. For example, you have to use their API to interact with the Datastore, and some things just don't work. Once you do the work to get your app running there, though, it turns out to be a fairly good deal.
