Enterprise Resource Planning (ERP) systems evolved from traditionally isolated applications such as payroll, billing, purchasing, sales, etc. – that neither shared a common base of data, nor interacted well with one another. The need for an integrated view of enterprise systems led to the development of sophisticated and complex software packages that could be tailored for different organizatio...

Cloud security has gained increasingly emphasis in the research community, with much focus primary concentrated on how to secure the operation system and virtual machine on which cloud system runs on. We take an alternative perspective to consider the problem of building a secure cloud storage service on top of a public cloud infrastructure where the service provider is not completely trusted b...

Objective: The main aim is to de-duplicate the redundant files in the cloud and also to improve the security of files in public cloud service by assigning privileges to the documents when it is uploaded by confidential user. Methods: To achieve the objective the authors have used the AES algorithm to encrypt the file stored after de-duplication in the cloud. De-duplication is done based on comp...

Recent technology advances have made the success of cloud computing by acquiring the infrastructure, platform and software from the third party vendor. The promising benefit of cloud computing is data service outsourcing, by which the data owners stores their data in the public data centers by economically saving their capital investment towards data management. Cloud Storage provide users with...

Cloud computing technology use central server and provide applications as services to users. The organization can take advantage of reducing the cost of hardware and software ownership and maintenance. Many surveys proved cloud computing reduces total cost of ownership. But due to centralized server approach there is always risk to system security. All applications required by different set of ...

This paper explores query processing in a hybrid cloud model where a user’s local computing capability is exploited alongside public cloud services to deliver an efficient and secure data management solution. Hybrid clouds offer numerous economic advantages including the ability to better manage data privacy and confidentiality, as well as exerting control on monetary expenses of consuming clou...

Data outsourcing allows data owners to keep their data in public clouds. However, public clouds do not ensure the privacy of data and computations. One fundamental and useful framework for processing data in a distributed fashion is MapReduce. In this paper, we investigate and present techniques for executing MapReduce computations in the public cloud while preserving privacy. Specifically, we ...

More and more companies begin to provide different kinds of cloud computing services for Internet users at the same time these services also bring some security problems. Currently the majority of cloud computing systems provide digital identity for users to access their services, this will bring some inconvenience for a hybrid cloud that includes multiple private clouds and/or public clouds. T...

Using Cloud computing user can store their data secure without load of local user computer. And this feature additionally should be cable enough to provide user to maintain the cloud storage, as it is if same is maintained in the local, where no consideration required verifying the data integrity. On top by enabling and having public audit for cloud storage, which cab check the integrity of dat...

Many popular cloud applications use inter-data center paths; yet, little is known about the characteristics of these “cloud paths”. Over an eighteen month period, wemeasure the intercontinental cloud paths of three providers (Amazon, Google, andMicrosoft) using client side (VM-to-VM)measurements. We find that cloud paths are more predictable compared to public Internet paths, with an order of m...
