Hybrid cloud storage infrastructure, which combines cost-effective but inflexible private resources and flexible but premium-priced public cloud storage, allows organizations to operate cost-efficiently under demand volume uncertainty. The extant literature, however, offers a limited analytical insight into the effect that the variation of demand has on the cost-efficient mix of internal and ex...

Cloud computing is getting an enormous popularity for software companies as a way to save and optimize the cost of large hardware and software infrastructure organizations demand. Also, the cooperation between cloud layers constitutes a timely research challenge as allocation and optimization of (often virtualized) resources is many times done in isolation or with poor interaction. In this pape...

—Cloud computing allows the users to access the shared pool of configurable resources such as compute, network and storage on-demand basis from the cloud Data Centers. Cloud storage provides the storage resources to the cloud users over the network. The massive growth of cloud data due to the applications such as video streaming, big data processing, social networking, banking and scientific a...

Security is an important concern to improve in emerging cloud computing to store, manage, analyze and share the sensitive data. Infrastructure as a Service (IaaS) is a provision cloud model attracting all business customers to use cloud by offering on-demand and pay-per-use hardware, storage, servers and other networking components. Present single cloud architectures are having numerous securit...

Mobile cloud computing is a new technology that enhances smartphone applications capabilities in terms of performance, energy efficiency, and execution support. These features are achieved via computation offloading technique that is supported by specialized mobile cloud application development models. However, the cloud-enabled applications are prone to application piracy issue for which the t...

Cloud computing is promising many technical benefits such as enhanced scalability, computing elasticity, and cost efficiency. However, with the benefits of cloud-based, hosted software platforms also comes the responsibility to data privacy. This paper investigates the data privacy issues brought about by cloud computing from an Australian perspective with specific focus on two aspects: How doe...

Data compression and deduplication are two common approaches to increasing storage efficiency in the cloud environment. Both users and cloud service providers have economic incentives to compress their data before storing it in the cloud. However, our analysis indicates that compressed packages of different data and differently compressed packages of the same data are usually fundamentally diff...

Could computing service providers have to ensure that the service applications, cloud software, and the physical location of the cloud are secure. Furthermore, providers need to ensure that the service is secure on the client’s side of the system. To examine the client side security level we build economic models that consider the tradeoffs between system usability and client side security rest...

Advancements in the areas of Cloud Computing, Internet of Things (IoT), and hybridHuman-Computer systems have made feasible the creation of a highly integrated human-machine world. The concept of elasticity plays a crucial role in fulfilling this vision, enabling systems to address various requirements reflecting performance, security, and business concerns. However, elastic systems are still i...

With the growth in the number of Cloud Service Providers, many enterprises and organizations are now able to use multiple Cloud platforms in order to achieve improved overall Quality of Service (QoS), reliability and cost efficiency. However, due to the diversity in architecture and functionalities among different Cloud platforms, it is difficult to build a system that simultaneously manages mu...
