The document discusses some principles for using cloud computing that were previously unexpected. It notes the massive amounts of data, users, transactions, and features that cloud services must support. Some key principles highlighted include relying on elasticity and pay-as-you-go models, designing for continuous delivery, handling faults and failures gracefully, automating everything possible, and testing in production environments. The document concludes by inviting interested parties to a hands-on lab for Windows Azure.
