Google App Engine
Google just launched a preview release of App Engine, I was lucky to be able to try it.
As Google describe it, “Google App Engine enables you to build web applications on the same scalable systems that power Google applications, Google App Engine makes it easy to build scalable applications that grow from one user to millions of users without infrastructure headaches..”
I’ve been learning Python the last few months, so I followed the tutorial and created an application. It’s currently limited to 3 applications, and I used-up one (you currently cannot delete applications).
