Using cloud infrastructures to store and backup data is becoming a popular alternative that guarantees performance and scalability at reasonable prices. However, standard cloud solutions could raise some concerns about data confidentiality and dependency on a single provider. We aim to address these issues by using cloud storage of multiple cloud providers. Our solution ciphers, partitions and replicates data among multiple cloud architectures, thus augmenting availability and confidentiality, and avoiding lock-in of one cloud provider. The proposed model is implemented through open source software that leverages data storage offered by multiple providers. This prototype demonstrates the effectiveness of the geographically distributed architecture in several real case scenarios.

Abstract
Using cloud infrastructures to store and backup data is becoming a popular alternative that guarantees performance and scalability at reasonable prices. However, standard cloud solutions could raise some concerns about data confidentiality and dependency on a single provider. We aim to address these issues by using cloud storage of multiple cloud providers. Our solution ciphers, partitions and replicates data among multiple cloud architectures, thus augmenting availability and confidentiality, and avoiding lock-in of one cloud provider. The proposed model is implemented through open source software that leverages data storage offered by multiple providers. This prototype demonstrates the effectiveness of the geographically distributed architecture in several real case scenarios.Pubblicazioni consigliate
