A Cloud Storage Architecture for High Data Availability, Reliability, and Fault-tolerance

The most important factors that need to be taken into consideration when designing a distributed storage system are data availability, reliability and access performance. This paper introduces an architecture to meet such goals by following the framework of cloud-of-clouds, where a complex system of clouds intercommunicate to create a robust and reliable cloud system. The optimal design of this architecture encompasses a general framework for achieving effective data reliability and availability, as well as fault tolerance. A simulation tool was developed to demonstrate the concept and functionality of the proposed architecture, testing its effectiveness in providing a reliable, available, and fault-tolerant cloud storage system. Simulation results proves that such architecture met the set goals to achieve the previously mentioned factors.
