Each week in our "Who's @ Google I/O" blog series, we'll highlight the latest from a featured track at I/O. This week, the spotlight is on Enterprise -- a major theme of this year's event.

In 2009, we saw an increasing number of large companies moving to the cloud (and "Going Google"), choosing the web as their platform of choice. At I/O, we'll share our enterprise and commercial developer offerings and focus on how to build business apps in the cloud.

We'll be adding new Enterprise sessions over the next couple of months, but here's a preview of some of the sessions you'll see at I/O:

Customizing Google Apps & integrating with customer environments
Hear real-life examples of customizing Google Apps to meet customer requirements from several panelists, including two of our Sandbox participants -- Iein Valdez of Appirio and Michael Cohn of CloudSherpas. Explore integration issues and deployment best practices with the people who have done it.

Run corporate applications on Google App Engine? Yes we do.
Our CIO, Ben Fried, describes how Google IT and other companies use the latest Google App Engine enhancements to respond more quickly to business needs while reducing operational burden to near zero.

It’s 2010: How is your move to the cloud doing?

This talk will give a complete overview of Google's commercial developer products and provide insights and best practices so enterprise developers can take more advantage of the cloud.

Launch your app inside of Google Apps with gadgets

This session will talk about how you can write gadgets as natural extensions of your existing products and take advantage of the unique opportunities available to gadgets in Google Apps.
