This morning, Google announced that over 3 million businesses, with over 30 million employees, are using its enterprise Apps product.

Google has made a habit of making these announcements each time it hits a major milestone with apps. In February 2009 Google announced that 1 million businesses and 10 million users were signed up. Since then, Google has made announcements about hitting 15, 20, 25, and now 30 million users.

That makes it pretty simple to get a rough approximation of Google Apps’ growth rate. So how is Google doing?
