Conceptualisation and Lifecycle of Cloud Based Information Systems

Cloud-computing is spreading quickly in industry. In the beginning, single cloud services have been in the center of interest. Nowadays, so called cloud environments are quickly gaining momentum. Cloud environments are collections of cloud services and resources. Cloud environments allow to build cloud based information systems. Cloud based information systems are configurations of services and resources provided by dynamic cloud-environments. To promote the development of a design methodology cloud based information systems are conceptualized using the entities provided by cloud environments. This static view is complemented by the definition of a life cycle described for cloud based information systems. Furthermore the notion of flexibility in cloud based information systems is discussed and first ideas for the enactment of business processes are introduced.
