First steps with Google App Engine

This evening I discovered Google App Engine.
It’s a complete application platform using Python, YAML and some Google API.
With the Google API one can create web applications incl. template engine and persistence and one can make use of the Google users.
It also provides a “Dashboard” where one can configure and monitor the applications.

I followed the tutorial and created my first app a simple guestbook.
My first opinion is, that Google App Engine is a great environment for developing smaller web applications. But I don’t have any idea how usefull it will be for bigger applications…

Try it out and let me know what you are thinking!
