Continuous and Client-Centric Trust Monitoring in Multi-Cloud Storage

Book Contribution - Book Chapter Conference Contribution

Multi-cloud storage is the practice of composing the data tier of an application with heterogeneous cloud storage technologies, resources and services. In a federated cloud storage architecture which involves multiple cloud storage providers, both the complexity and the importance of trust management increases drastically. A trust relation is established between a data owner and a cloud storage provider when the data owner subscribes to the service and service level agreements (SLAs) are established. In practice, this trust relation is seldom revised, only when serious infractions are discovered and made public. In this paper, we evaluate the potential of continuous and client-centric trust monitoring of cloud storage services. This approach leverages upon the statistical correlations between black-box performance metrics and reported white-box metrics, and identifies significant deviations between both. We evaluate in terms of (a) the effectiveness of correlating black-box and white-box measurements, and (b) the incurred performance overhead of the approach to continuously monitor for trust.
