Effective Data Distribution Techniques for Multi-Cloud Storage in Cloud Computing

Cloud data storage redefines the issues targeted on customer’s out-sourced data (data that is not stored/retrieved from the costumers own servers). In this work we observed that, from a customer’s point of view, relying upon a solo SP for his outsourced data is not very promising. In addition, providing better privacy as well as ensure data availability and reliability can be achieved by dividing the user’s data block into data pieces and distributing them among the available SP s in such a way that no less than a threshold number of SP s can take part in successful retrieval of the whole data block. In this paper, we propose a traditional technique followed to distribute data to multi-cloud storage model in cloud computing which holds an economical distribution of data among the available SPs in the market, to provide customers with data availability as well as reliability . Data fragmentation plays an important role in data distribution
