Brent Ozar and I had an interview with Jeff James over at SQL Server Magazine. The topic was virtualization, where Brent and I were able to riff extensively on the topic. I encourage you to take a look here.
And if you haven't already checked it out, look at Brent's excellent blog. Here's a good place to start: http://www.brentozar.com/archive/2009/02/sql-server-and-cloud-links-for-the-week-14/.
Enjoy!
