Yesterday, GigaOM's Structure 09 conference took place in San Francisco, focused on cloud computing. At GigaOm.com, you can find a number of good posts on what everyone from venture capitalists to Salesforce.com CEO Mark Benioff had to say about cloud computing. Notably, more than a few of the speakers at the conference expressed caution toward the cloud, and, as we've pointed out on a number of occasions, quite a few of the cloud pundits clearly recognize that open source solutions and more favorable economics are essential to a healthy cloud ecosystem.

The GigaOM Network, parent of OStatic, is holding its second annual Structure conference today, at the Mission Bay Center in San Francisco. As we reported before, the conference is focused on the fast-growing cloud computing arena, and features a number of top movers and shakers. Marc Benioff, CEO of Salesforce.com and Paul Sagan, CEO of Akamai, are speakers at the event, among many other notables.
