Cloud computing — Between hype and profitable business model

Cloud computing is getting increasingly important part of IT strategies in modern organizations [5] and nowadays it is generally positioned in broad context of strategic planning of information systems [2] [3]. Since cloud services can appear in various flavors (software as a service, platform as service, etc.) there is no one common approach to their incorporation into certain business and organizational context. In many cases they are basically extending existing architectures making them integral part of broader information system based on service oriented architecture. These architectures are quite structurally complex [6] [8] [10] and should be carefully planned and implemented to achieve business benefits and competitive advantage.
