Cuts through the complexity to just what's needed.
Practically unlimited storage, instant scalability, zero-downtime upgrades, low start-up costs, plus pay-only-for-what-you-use without sacrificing security or performance are all benefits of cloud computing. But how do you make it work in your enterprise? What should you move to the cloud? How? And when?
The Cloud at Your Service answers these questions and more. Written for IT pros at all levels, this book finds the sweet spot between rapidly changing details and hand-waving hype. It shows you practical ways to work with current services like Amazon's EC2 and S3. You'll also learn the pros and cons of private clouds, the truth about cloud data security, and how to use the cloud for high scale applications.
