David and TechNet EDGE team have just published a screencast on Microsoft’s security of our cloud infrastructure. The interview is with John Howie and Mark Estberg who are part of Global Foundation Services Online Services Security and Compliance group, and they talk about how Microsoft secures it's cloud infrastructure. You should be able to take away some best practices for your own organization moving to the cloud.

This is a great “all in” discussion.
