Data Security in Decentralized Cloud Systems: A Case for the Deployment of Blockchain Technology.

Abstract

The technological advancement and growth of the cloud computing technologies is changing network service provisioning and operation. Cloud based services represented as XaaS where X refers to service offering such as Platform, Software and Infrastructure as a service, provides flexible on-demand provisioning along with its security concerns that goes with the adoption of the cloud computing. Despite all the advantages of adopting the cloud computing option, the security and privacy of the clients’ data cannot be overlooked. Understanding these security concerns is a fundamental requirement to choosing the cloud solution. This paper focuses on the use of Blockchain technology to mitigate the security challenges of the cloud computing. Literature reviews have discussed other security options for the cloud, but little discussions have centered on the adoption of the Block Chain technology to secure the cloud and open doors for future research of cloud computing using smart contract.
