Gartner defines Cloud 1.0 as “a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service to external customers using internet technologies”. However, Gartner’s definition is more appropriate for Cloud 2.0 as opposed to Cloud 1.0.
Amazon’s S3 (Simple Storage Service) is a good example of a Cloud 1.0 proposition where the focus is on highly reliable, scalable storage with a robust security layer, limited to a customer specified region, for example Europe.
