How does cloud computing differ from regular hosting?

• It is sold on demand, typically by the minute or the hour; • It is elastic -- a user can have as much or as little of a service

as they want at any given time• The service is fully managed by the provider (the consumer

needs nothing but a personal computer and Internet access).
