Advance DATA PROCESSING In Peer to Peer Technology With Peer++ Approach
ABSTRACT:
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.
EXISTING SYSTEM:
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
‘Chubby’ is a unified lock service created by Google to synchronize client activity with loosely coupled distributed systems. The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.
Furthermore, the number of communications between C1 and C2 is constant. To perform range queries over encrypted integers in the cloud, we assume the data owner has encrypted and outsourced their database to C1. Integers in particular are encrypted using their bit representation. The lower and upper bound of the query are encrypted in a similar fashion. The comparison protocol is executed for every record.
Back in 2013, our organization decided to purchase and implement the latest software that was available which was promised to better serve our types of industry. It was one of the biggest financial investment that our company made anticipating reasonable production and performance returns within a year of implementation the new system. It has been nearly three years that we have not yet utilized 50 % of the performances that was promised. In fact this upgrading took us back by requiring us to do some manual work because we can 't do what we were able do with our old system. Although several factors played in this circumstance.
6. Data owner pays to TPA to get security of its data and can access valuable data at anytime. 7.7.2 Cloud Server 1. One whose going to access files, one who owns file, who requires his data to be secure.

Not only will these innovations improve network strength, but possibly the speeds at which a client can access information from an application server. This has the potential to make cloud computing even more prevalent than it already is today because it would become easier to keep up with mass traffic to the servers. Large server banks would be able to be downsized slightly compared to their current sizes. The computer science techniques used in created Marple show that it is possible to even make an old process useful in modern applications. The hardware of Marple is also programmable making it extremely useful for any network engineers because they will be able to write custom software for Marple-based

It can be used for backup, record and calamity recovery, and content storage, allocation and data analysis storage. S3 is current as part of the free Amazon Elastic Compute Cloud (EC2) tier service for 5GB of storage, 20,000 Get Needs or 5,000 Put Needs per month.
Goals of the Lab This lab has many different overall goals that are meant to introduce us to the challenges and procedures of building a preliminary enterprise environment from the ground up. Each task has it’s own set of goals that expose us to important areas of system administration in this type of environment. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case the Internet. The lab then introduces installation of an enterprise Linux distribution, Red Hat Enterprise Linux 7, which will be used as the main Linux based server in our enterprise environment.
Every page, folder, template, group and user record has an audit trail that captures every change made, with the date/time and user stamp to indicate who made the change and when. Users with appropriate security access can view this information, and reporting is also available to pinpoint specific types of changes or to narrow down records to specific time frames. 6. How does the system ensure availability, security and privacy of data on shared
For example, a data warehouse can be constructed to extract and consolidate data from various computer systems or a workflow management system can be used to coordinate activities across several offices such as who works on what activity and how long it takes them to complete a task. Another way to shorten the close process is to centralize all accounting operations in one location. This allows the company to concentrate all of its efforts on improving the efficiency of a single
2.7 Observations from GMPCS Model Based on the above model, several observations can be made as follows. Observation_1: According to an interoperability feature between CSPs, a storage service will be hosted over a pool of resources that are in different geographical locations. Furthermore, different technologies, protocols, and security strategies are applied by each CSP within its datacentres to facilitate managing an environment to protect both resources and data. The technologies and strategies, therefore, might be disparate in terms of efficiency, and the type of storage network or storage system might be varied as well.
