So, What is Cloud Computing?Suitably vague and varied.. Don’t expect to converge! Some attempts:
The 451 Group: “The cloud is IT as a Service, delivered by IT resources that are independent of location”
Gartner: “Cloud computing is a style of computing where massively scalable IT-related capabilities are provided ‘as a service’ across the Internet to multiple external customers”
Forrester: “A pool of abstracted, highly scalable, and managed infrastructure capable of hosting end-customer applications and billed by consumption”

The challenge is to do this …• At massive scale
•Millions of users
• With unprecedented flexibility•Mash-ups, aggregation, enhancing services, flexing up
and down, ...•Offering evolving APIs to exploit and extend
• At breakthrough cost levels•Economies of scale, sharing resources and IT expertise •Extreme automation
