摘要：Cloud computing has emerged as a new model of computing. It is a paradigm shift in computing history. Cloud services can be availed without capital investment as they are commoditized. Cloud users get services in pay per use fashion and enjoy many benefits of cloud including low cost and accessibility from anywhere in the world. However, users have security concerns as they outsource their valuable business data to cloud and treat the cloud as "untrusted". With a single cloud service provider there might be the risk of service availability, failure possibility and insider theft of data. Moving towards multiple clouds can address security problems. This paper aims of investigating how multi-cloud deployments can reduce security risk and have impact on the usage of the cloud computing technology. We built a prototype application to simulate the advantages of using multi-clouds to improve security. The empirical results revealed that multi-clouds can reduce security risks
