Wow! Google just announced Google App Engine which will allow users to host their python applications on their server infrastructure similar to Amazon's EC2 services, but in a more straight-forward manner. The timing is perfect, as I am in the middle of evaluating virtualized hosting for our newspaper websites. The fact that they've started with python and django as the core runtime is huge.
That said, all is not perfect. As Eric and I read more into this, there appear to be some serious limitations. The google model library seems simplistic, even by django standards ( don't ask the sqlalchemy folk to weigh in on this one ). Eric has a more complete write-up on this.
Pricing is yet to be set. I hope it is reasonable. For my own personal uses, EC2 turned out to be quite expensive compared to the great service I get from SliceHost.
I wonder how this will effect all of the smaller hosting companies out there. Free accounts were given to the first 10k users to sign up, and I was pitifully slow in doing so, so I am on the waiting list. Does anyone know if the next wave of accounts will be doled out in order or via a lottery process? ( or maybe invites like gmail did? )
