Google App Engine

I started seeking the API & Developer section and got attracted by the Google App engine.
What really caught my attention is creating Web application hosted by Google where I use Google Technology or API or something like that.

Another thing, I remember a time I see a Google service (that I don't remember well!) where in the bottom there's Built by Google App Engine, which means that this one is powerful and I hope so.

As the hosting of my project or web application was free and instantly I didn't thought and signed up. I also gave a look to the app engine blog to see what's going on, on it.

Quickly I arrived to the start page and hit "Create an application" to see how it works.

If it really was easy to use it then it'll be so cool, because:

• No assembly required, like an old MS-Dos stand alone
• Free hosting with 500mb and 5 million page view in a month

Could you understand this one, I read it on the home page:

It's easy to scale.
Google App Engine makes it easy to build scalable applications that grow from one user to millions of users without infrastructure headaches.

What does this really mean, from 1 to 1 million? Does it work like Facebook? Is their any massive distribution for my application?

We are going to know....
