Traditionally, computing has meant calculating results and then storing those results for later use. Unfortunately, committing large volume of rarely used data to storage wastes space and energy, making it a very expensive strategy. Cloud computing, with its readily available and flexibly allocatable computing resources, suggests an alternative: storing the provenance data, and means to recompu...

Peer-assisted cloud storage systems use the unutilized resources of the clients subscribed to a storage cloud to offload the servers of the cloud. The provider distributes data replicas on the clients instead of replicating on the local infrastructure. These replicas allow the provider to provide a highly available, reliable and cheap service at a reduced cost. In this work we introduce NileSto...

Cloud computing has gained great attention from both industry and academia since 2007.With the goal of providingusersmore flexible services in a transparent manner, all services are allocated in a “cloud” that actually is a collection of devices and resources connected through the Internet. One of the core services provided by cloud computing is data storage. This poses new challenges in creati...

High-performance computing (HPC) demands high bandwidth and low latency in I/O performance leading to the development of storage systems and I/O software components that strive to provide greater and greater performance. However, capital and energy budgets along with increasing storage capacity requirements have motivated the search for lower cost, large storage systems for HPC. With Burst Buff...

Cloud storage permits users to remotely store their knowledge and revel in the on-demand top quality cloud applications while not the burden of native hardware and software package management. Though the advantages are clear, such a service is addition relinquishing users’ physical possession of their outsourced knowledge, which necessarily poses new security risks towards the correctness of th...

Relative to the current Master/Slave computing model cloud storage file systems, including GFS, HDFS, Sector, we proposed a general model of Peer-to-Peer based Cloud Storage file system, and constructed a prototype system named MingCloud based on Kademlia algorithm. Focused on redundant strategy selection and design of the storage system, our experiment used the Cauchy Codes as coding algorithm...

To date, the cloud storage system has been well developed. It is a system that provides users with large storage, high computation ability, and convenience. However, users cannot fully trust a cloud storage system because it is an “honest but curious”server. For this reason, protecting data confidentiality and data integrity are two important issues in a cloud storage system. In this paper, we ...

Cloud computing is a rapidly growing segment of the IT industry that will bring new service opportunities with significant cost reduction in IT capital expenditures and operating costs, on-demand capacity, and pay-per-use pricing models for IT service providers. Among these services are Software-as-a-Service, Platform-as-a-Service, Infrastructure-as– a-Service, Communication-as-a-Service, Monit...
