Cloud storage services are increasing in popularity and using a growing amount of bandwidth on the Internet. Insights on how much traffic is generated is needed for a number of reasons. Cloud storage providers are interested in serving their clients efficiently and effectively, and they want to know how their product is performing and how they can improve their service. Internet Service Provide...

Nowadays, more and more users store their data in cloud storage servers for great convenience and real benefits offered by the service, so cloud data storage becomes one of the desirable services provided by cloud service providers. Multi-Authority Ciphertext-Policy Attribute-Based Encryption (MA-CP-ABE) is an emerging cryptographic solution to data access control for large-scale collaborative ...

Cloud computing is one of the emerging forms of modern computing due to its many advantages. The security in the cloud data storage has become an important aspect of quality of service. As the number of users is on the tremendous increase, there arise many more issues since users look for the space to store sensitive data in the cloud. Along with variant advantages, the cloud storage has gained...

Cloud computing has emerged as a popular computing paradigm in recent years. However, today’s cloud computing architectures often lack support for computer forensic investigations. A key task of digital forensics is to prove the presence of a particular file in a given storage system. Unfortunately, it is very hard to do so in a cloud given the black-box nature of clouds and the multi-tenant cl...

ARTICLE INFO Today is the most important issue in cloud computing is duplication for any organization, so we analysis this issue an avoid the reparative files on cloud storage. Avoidance of the file is advantages the cloud size issue. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before ...

Few cloud storage systems can handle random read accesses efficiently. In this paper, we present a RAMCloud Storage System, RCSS, to enable efficient random read accesses in cloud environments. Based on the Hadoop Distributed File System (HDFS), RCSS integrates the available memory resources in an HDFS cluster to form a cloud storage system, which backs up all data on HDFS-managed disks, and fe...

Cloud storage services are becoming increasingly popular due to their flexible deployment, convenient pay-per-use model, and little (if any) administrative overhead. Today they are being offered by ever growing number of Internet companies, such as Amazon, Google, Microsoft as well as numerous smaller providers, such as Rackspace, Nirvanix and many others. Although cloud storage providers make ...

In tradition, we always simply purchase additional machines to solve the storage problems. However, this method only expands the storage capacity. It is un-efficient and high-cost, which cannot solve the storage problems due to the architecture issue. After future analyzing the reasons of storage issue, we bring the cloud computing and cloud storage technology (a rich client-based cloud storage...

Cloud storage is growing at a phenomenal rate and is fueled by multiple forces: Mobile Devices, Social Networks, and Big Data. Content is created any time and any where on billions of smartphones and tablets; high resolution photos and videos are frequently uploaded to the cloud automatically as soon as they are captured. A Gartner Report predicts that consumer digital storage would grow to 4.1...

There are limits to the ability to migrate or deploy applications across geographically distributed/loosely coupled cloud resources, requiring substantial data movement and/or uniformly visible and accessible storage services across such distributed infrastructure. To address these issues, we propose and explore the utility of FleCS – an approach for providing FLExible Cloud Storage services in...
