Advance DATA PROCESSING In Peer to Peer Technology With Peer++ Approach
The corporate network is often used for sharing information among the participating companies and facilitating collaboration in a certain industry sector where companies share a common interest. It can effectively help the companies to reduce their operational costs and increase the revenues. However, the inter-company data sharing and processing poses unique challenges to such a data management system including scalability, performance, throughput, and security. In this paper, we present BestPeer++, a system which delivers elastic data sharing services for corporate network applications in the cloud based on BestPeer—a peer-to-peer (P2P) based data management

We evaluate BestPeer++ on Amazon EC2 Cloud platform. The benchmarking results show that BestPeer++ outperforms HadoopDB, a recently proposed large-scale data processing system, in performance when both systems are employed to handle typical corporate network workloads. The benchmarking results also demonstrate that BestPeer++ achieves near linear scalability for throughput with respect to the number of peer nodes.
The corporate network needs to scale up to support thousands of participants, while the installation of a large-scale centralized data warehouse system entails nontrivial costs including huge hardware/software investments (a.k.a total cost of ownership) and high maintenance cost (a.k.a total cost of operations). In the real world, most companies are not keen to invest heavily on additional information systems until they can clearly see the potential return on investment (ROI). Second,

companies want to fully customize the access control policy to determine which business partners can see which part of their shared data. Unfortunately, most of the data warehouse solutions fail to offer such flexibilities. Finally, to maximize the revenues, companies often dynamically adjust their business process and may change their business partners. Therefore, the participants may join and leave the corporate networks at will. The data warehouse solution has not been designed to handle such

BestPeer++ adopts the pay-as-you-go business model popularized by cloud computing. The total cost of ownership is therefore substantially reduced since companies do not have to buy any hardware/software in advance. Instead, they pay for what they use in terms of BestPeer++ instance’s hours and storage capacity. BestPeer++ extends the role-based access control for the inherent distributed environment of corporate networks. Through a web console interface, companies can easily configure their access control policies and prevent undesired business partners to access their shared data. BestPeer++ employs P2P technology to
