Multivendor Portfolio Strategies in Cloud Computing
Cloud computing emerges as a powerful driver of the information technology industry and many companies are willing to exploit the advantages this development bears. However, services provided by the cloud are subject to default which can result in major economic damage for the client. Moreover, different cloud service providers may also bear a conjoint risk and may therefore not default independently. Hence, to implement effective cloud sourcing strategies, this paper postulates requirements for evaluating multivendor sourcing decisions to select cloud service providers, considering cost, cloud computing specific risk, and interdependencies.
