Cloud storage service is one of cloud services where cloud service provider can provide storage space to customers. Because cloud storage service has many advantages which include convenience, high computation and capacity, it attracts the user to outsource data in the cloud. However, the user outsources data directly in cloud storage service that is unsafe when outsourcing data is sensitive fo...

Cloud storage has become popular and is being used to hold important data. As a result, availability to become important; cloud storage providers should allow users to upload or download data even if some part of the system has failed. In this paper, we discuss distributed cloud storage that is robust against failures. In distributed cloud storage, multiple replicas of each data chunk are store...

Cloud computing technology has matured, so cloud computing produces a wide range of cloud service. Cloud storage services are one of cloud services where cloud service provider can provide storage space to customers. Because cloud storage services bring a lot of convenience, many enterprises and users store the data to the cloud storage. However, the user will outsource data to the cloud storag...

Cloud computing is the computing technology which provides resources like software, hardware, services over the internet. Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Since the data transmission on the internet or over any networks are ...

Personal cloud storage services have attracted the attention of users thanks to this great accessibility. Personal cloud storage services allow users to synchronize their local files with the servers in the cloud in order to make them accessible from anywhere, on any device, and at any time thanks to the client applications provided by the vendors. Various experiments are evaluated on Dropbox, ...

This thesis evaluates and develops, where this is needed and possible, the technical principles of a cloud marketplace. These basic principles are infrastructure services for managing and provisioning computational power, persistent storage and (virtual) network resources. Furthermore tools are needed to integrate the resources in the form of services and provide the customers a uniform user in...

In this paper we describe our experience in investigating private cloud storage solutions and architectures for long-term data archival storage purpose. The storage solution needs in a campus research environment requires reliability and scalability up to petabytes of data at the minimum. The key requirements for a reliable and scalable cloud storage architecture is discussed below along with p...

Current de facto standard payment and billing models for commercial cloud storage services provide a plethora of information to the cloud provider about its clients. This leads to a hostile environment when seen from a privacy perspective. Motivated by recently leaked facts about large scale governmental surveillance efforts as well as the lack of privacy-preserving measures in existing commerc...

The advent of the cloud era has yielded new ways of storing, accessing and managing data. Cloud storage services enable the storage of data in an inexpensive, secure, fast, reliable and highly scalable manner over the internet. Although giant providers such as Amazon and Google have made a great success of their services, many enterprises and scientists are still unable to make the transition i...

Along with the evolution of cloud computing and cloud storage towards maturity, researchers have analyzed an increasing range of cloud computing security aspects, data security being an important topic in this area. In this paper, we examine the state of the art in cloud storage security through an overview of selected peer reviewed publications. We address the question of defining cloud storag...
