Effective Optimization of Multi-Clouds using Software-as-a-Service

Ensuring the security of cloud computing is a major factor in the cloud computing environment which has many benefits in terms of low cost and accessibility of data, as users often store sensitive information with cloud storage providers, unaware that these providers may be compromised. Dealing with “single cloud” providers is predicted to become less popular with customers due to risks of service availability failure and the possibility of malicious insiders in the single cloud. A movement towards “multi-clouds” or in other words, “inter clouds”or“cloud-of-clouds has emerged recently and a system that employs Byzantine protocol for secret sharing has been constructed. We aim to equip Depsky framework to supply a secure cloud database that will guarantee to prevent security risks facing the cloud computing community. In relation to data intrusion and data integrity, like depsky we distribute the data and metadata into different cloud providers, and we apply the Software-as-a-Service (SaaS) on the stored data in the cloud provider. Instead of using plain secret sharing using public key ciphers we employ Software-as-a-Service (SaaS). Hence, replicating data into multi-clouds by using a multi-share technique may reduce the risk of data intrusion and increase data integrity. This work aims to promote the use of multi-clouds due to its ability to reduce security risks that affect the cloud computing user.
