Use the Google App Engine platform to run web apps on Google's infrastructure, the same scalable systems that run Google applications. Use the platform to run your apps reliably, even if you have heavy load and data needs. The environment has dynamic web serving, persistent storage with queries, sorting and transactions, automatic scaling and load balancing, APIs for authenticating users and sending email using Google Accounts, and a local testing environment. Google App Engine apps are implemented using the Python programming language, with support for most of the Python standard library. App Engine recently unveiled its second language: Java. This release includes the Java runtime, integration with Google Web Toolkit, and a Google Plugin for Eclipse, giving you an end-to-end Java solution for AJAX web applications.
