In particular, start-up companies can benefit from Cloud Computing Services as they often do not operate an internal IT infrastructure. In this article we introduce a Total Cost of Ownership (TCO) approach for Cloud Computing Services. We applied a multi-method approach (systematic literature review, real Cloud Computing Services analysis, expert interviews, case study) for the development and evaluation of a formal mathematical model of TCO. Findings (required): We find that the decision processes in Cloud Computing are carried out ad hoc and lack systematic methods. The method presented increases awareness of indirect and hidden costs in Cloud Computing. Limitations / implications of research (if applicable): We made some restrictive assumptions. For example, hide cost types that focus on an existing internal IT infrastructure. Future research can combine risk and safety aspects through a TCO approach. In addition, profit management in Cloud Computing is another new field of research that can be explored, for example, by cost-benefit analysis. Practical implications (if applicable): Analysing the types of costs and relevant factors in Cloud Computing Services is an important pillar of cloud computing decision making. The software tool allows easy application of the TCO model with reasonable effort. Originality / value (mandatory): We provide a mathematical model evaluated for the calculation of Cloud Computing Services TCO. With this tool, decision makers can decide whether cloud outsourcing is monetarily attractive, to be more specific, if the costs associated with Cloud Computing Services are less than i. my. A pre-existing infrastructure.
