An Approach to Selecting Cloud Services for Data Storage in Heterogneous-Multicloud Environment with High Availability and Confidentiality

Cloud services are becoming more popular and as their price has been decreasing, the opportunity to use them has been increasing. However, it has become difficult to select optimal cloud services from many services. This paper proposes an approach to dynamically selecting optimal cloud services to store data in heterogeneous-multi-cloud environments, which we evaluated by using a secret sharing scheme. The results indicated that it is possible to select the best services from the proposed model in heterogeneous multi-cloud environments.
