Comparative Study on Decentralized Cloud Collaboration(DCC)

Cloud collaboration is a billion-dollar industry, for sharing, storing, and co-authoring files. In the current age of information technology, cloud collaboration expects to see a significant amount of growth, as more organizations look to leverage the benefits of the industry specifically in the areas of flexibility, cost-efficiency, and security[1]. However, existing systems basically operates in a centralized cluster to achieve high performance, though they have a demand solving indisputable benefits, there are several inherent weaknesses such as high server costs for service providers, illegal data mining in trust-based architecture, security loopholes, and unethical government surveillance. Therefore, a large-scale resource sharing decentralized system can mitigate these traditional server expenses, data failure, and outage, as well as the enhanced security, and privacy of data. This dissertation presents a background to the problem, its impact on adaption, existing research background, and proposing design for storing, sharing, and coauthor files. The Design presents a decentralized resource (storage and network) sharing system, with real-time collaborative editing, peer (node) management, and redundancy schemes to manage fault tolerance of the distributed storage.
