Abstract

Cloud Computing has become the predominant paradigm for the use of distributed resources like computing power, storage capacities, data and software applications. But still there is no uniform definition of cloud computing. One reason why the term cloud computing is difficult to capture is the missing classification with regard to other approaches like grid computing, software as a service, platform as a service and infrastructure as service. In the last years, grid computing is being widely accepted when the distribution of high performance computing is needed in virtual organizations. Research on grid computing started in research when the need for high performance processing and management of a great amount of data became necessary in disciplines like high energy physics, climate research, astrophysics, engineering, medicine and life science [Schwiegelshohn 2008]. From research grid computing went to industry. This leads to additional requirements
