Application Of Ict: Potential Of Cloud Computing Architecture, Saira Begum, Muhammad Khalid Khan

International Conference on Information and Communication Technologies

Cloud computing is a massively central advancement in the technique that businesses and users devour and work on computing. It's a elementary modify to an prepared model in which applications don't subsist out their lives on a specific section of hardware and in which possessions are more supplely deployed than was the historical standard. It's a primary shift to expansion and utilization model that replaces hard-wired, proprietary associations surrounded by software components and the clients of those components with unimportant Web services and Web-based software admittance. As difficulty under the virtualization is how to allocate resources to every application on-demand …

Use Of Service Oriented Architecture For Scada Networks, Scott H. Beavers

Regis University Student Publications (comprehensive collection)

Supervisory Control and Data Acquisition (SCADA) systems involve the use of distributed processing to operate geographically dispersed endpoint hardware components. They manage the control networks used to monitor and direct large-scale operations such as utilities and transit systems that are essential to national infrastructure. SCADA industrial control networks (ICNs) have long operated in obscurity and been kept isolated largely through strong physical security. Today, Internet technologies are increasingly being utilized to access control networks, giving rise to a growing concern that they are becoming more vulnerable to attack. Like SCADA, distributed processing is also central to cloud computing or, more …

A Cost-Benefit Analysis Of A Campus Computing Grid, Preston M. Smith

Purdue Polytechnic Masters Theses

Any major research institution has a substantial number of computer systems on its campus, often in the scale of tens of thousands. Given that a large amount of scientific computing is appropriate for execution in an opportunistic environment, a campus grid is an inexpensive way to build a powerful computational resource. What is missing, though, is a model for making an informed decision on the cost-effectives of a campus grid. In this thesis, the author describes a model for measuring the costs and benefits of building a campus computing resource based on the institution’s existing investment in computing hardware.

Haskell For The Cloud, Andrew P. Black

Computer Science Faculty Publications and Presentations

We present Cloud Haskell, a domain specific language for developing programs for a distributed-memory computing environment. Implemented as a shallow embedding in Haskell, it provides a message-passing communication model, inspired by Erlang, without introducing incompatibility with Haskell's established sharedmemory concurrency. A key contribution is a method for serializing function closures for transmission across the network. Cloud Haskell has been implemented; we present example code and some preliminary performance measurements.

Shared Memory, Message Passing, And Hybrid Merge Sorts For Standalone And Clustered Smps, Atanas Radenski

Mathematics, Physics, and Computer Science Faculty Books and Book Chapters

While merge sort is well-understood in parallel algorithms theory, relatively little is known of how to implement parallel merge sort with mainstream parallel programming platforms, such as OpenMP and MPI, and run it on mainstream SMP-based systems, such as multi-core computers and multi-core clusters. This is misfortunate because merge sort is not only a fast and stable sort algorithm, but it is also an easy to understand and popular representative of the rich class of divide-and-conquer methods; hence better understanding of merge sort parallelization can contribute to better understanding of divide-and-conquer parallelization in general. In this paper, we investigate three …

A Clouded Future: Analysis Of Microsoft Windows Azure As A Platform For Hosting E-Science Applications, Ian Blair

Regis University Student Publications (comprehensive collection)

Microsoft Windows Azure is Microsoft's cloud based platform for hosting .NET applications. Azure provides a simple, cost effective method for outsourcing application hosting. Windows Azure has caught the eye of researchers in e-science who require parallel computing infrastructures to process mountains of data. Windows Azure offers the same benefits to e-science as it does to other industries. This paper examines the technology behind Azure and analyzes two case studies of e-science projects built on the Windows Azure platform.

Cloud Computing:Strategies For Cloud Computing Adoption, Faith Shimba

Dissertations

The advent of cloud computing in recent years has sparked an interest from different organisations, institutions and users to take advantage of web applications. This is a result of the new economic model for the Information Technology (IT) department that cloud computing promises. The model promises a shift from an organisation required to invest heavily for limited IT resources that are internally managed, to a model where the organisation can buy or rent resources that are managed by a cloud provider, and pay per use. Cloud computing also promises scalability of resources and on-demand availability of resources.

Although, the adoption …

Cloud Services From A Consumer Perspective, Philip Koehler, Arun Anandasivam, Dan Ma

Research Collection School Of Computing and Information Systems

Although there is an increased attention on Cloud Computing in the academic literature in the recent years, most research work focus on technical aspects of cloud computing. Research on consumers’ preferences for cloud services is limited to studies from consulting and industry companies. This paper fills the gap by empirically identifying consumer preferences for cloud service attributes. Using conjoint methods we reveal the relative importance of different attributes of cloud services. The results help both practitioners and academic researchers to better understand the prerequisites of a successful market introduction of cloud services and to design appropriate services. Moreover, the derived …

Data Protection Models For Service Provisioning In The Cloud, Dan Lin, Anna Squicciarini

Computer Science Faculty Research & Creative Works

Cloud computing enables highly scalable services to be easily consumed over the Internet on an as-needed basis. While cloud computing is expanding rapidly and used by many individuals and organizations internationally, data protection issues in the cloud have not been carefully addressed at current stage. in the cloud, users' data is usually processed remotely in unknown machines that users do not own or operate. Hence, users' fear of confidential data (particularly financial and health data) leakage and loss of privacy in the cloud becomes a significant barrier to the wide adoption of cloud services. to allay users' concerns of their …

Your Local Cloud-Enabled Library, George K. Thiruvathukal

Computer Science: Faculty Publications and Other Works

Libraries are an important onramp for technology. They're known for making books accessible and have been pioneers in database access, but many branches seem to understand that they have a vital cultural role to play, especially when it comes to technology access. Most people in American society presume such access is ubiquitous, even though a substantial percentage of the world population lacks access.

Intelligent Information Management Tools In A Service-Oriented Software Environment, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

This paper draws attention to the increasing need for agile and adaptive software environments that are capable of supporting rapid re-planning during the execution of time-critical operations involving commercial end-to-end supply chain transaction sequences, as well as disaster response and military missions. It is argued that such environments are currently best served by information-centric software tools executing within a service-oriented paradigm. Service-oriented architecture (SOA) design concepts and principles are described, with a focus on the functions of the services management framework (SMF) and enterprise service bus (ESB) components. Differentiating between data-centric and information-centric services, it is suggested that only intelligent …
