Run your web applications on Google&#8217-s infrastructure.

Matt Cutts:

Google launched App Engine, which lets you write code for a web application, then Google takes care of the scaling/failover/logistics-type issues. You can store your data in a Google Bigtable using the Google File System (GFS). There’s a bunch of App Engine APIs to simplify things like sending email and fetching urls. Your application can authenticate users that are using Google Accounts, so you can avoid the whole “ask your users to create a new account” issue if you want.
