Google unveiled a preview version of its new hosted Web application platform, Google App Engine, late Monday. The new service is more than a simple database-style platform; rather, it provides developers of Web apps with a hosted solution upon which they can write their applications. Google App Engine is a way for developers to run their Web applications using Google's extensive infrastructure. The company's goal is to make it easier for developers to get their applications up and running and also make it easier to scale once millions of users begin using the application.
