Cloud computing is being used in every domain like business, industries, corporate sectors. Through cloud computing one can access hardware and software promptly through internet. Application of cloud computing in libraries is a relatively new area as compared to its applications in business and corporate sector. Libraries all over the world are moving towards cloud computing implementation to use...
Computing services are defined via various models, most of which are technology focused. As services become more diverse and divisions between them less clear-cut, a new way of describing and comparing IT services for research is needed. We present a hierarchy of the needs experiences by an individual carrying out e-Research. It considers each area of need and how a service provider might meet them...
The long-dreamed vision of “computing as a utility” has finally taken shape in the form of cloud computing. This paradigm shift is the biggest buzz in today's computer world. It can be thought of an evolution of existing technologies rather than a revolution. The basic requirements of cloud are to meet the various needs of enterprise organizations such as scalability, adaptability, extensibility and...
The demand in computing and Internet has been increasing since the day of invention. The continuous increase in needs of computerised infrastructure and internet framework has led to big demands for computer experts. In the present day there is a big implementation of hardware along with software. Although has been a significant improvement in reducing the size of hardware and increasing the capacity...
Both grid and cloud are used to organize large scale calculations and data processing on remote computers. Grid which became a basic computing infrastructure for the Large Hadron Collider experiments provides unified technical solutions for sharing and merging distributed heterogeneous computing resources within big collaboration groups. Cloud became popular among data centers and computing service...
Cloud computing promises to offer great opportunities for research groups; however when researchers want to execute applications in cloud infrastructures many complex processes must be accomplished. In this paper we present the e-Clouds project which will allow researchers to easily execute many applications on public Infrastructure as a Service (IaaS) solutions. Designed for being a Software as a...
In this article, we examine the technology acceptance of cloud computing by analyzing empirical data from 100 CIOs and IT managers from stock indexed companies using factor analysis. For a valid methodological background we use a modified version of the common Technology Acceptance Model. The outcomes indicate that user acceptance of cloud computing can be explained and predicted by various non monetary...
The advent of Cloud computing has paved the way to envision hybrid computational infrastructures based on powerful Grid resources combined with dynamic and elastic on-demand virtual infrastructures on top of Cloud deployments. However, the combination of Grid and Cloud resources for executing computationally intensive scientific applications introduces new challenges and opportunities in areas such...
Recently GPU computing, namely the possibility to use the vector processors of graphics card as computational general purpose units of High Performance Computing environments, has generated considerable interest in the scientific community. Some communities in European Grid Infrastructure (EGI) are reshaping their applications to exploit this new programming paradigm. Each EGI community, called Virtual...
The Grid computing vision promises to provide the required platform for users to run a new and more demanding range of high performance computing (HPC) applications. However, the performance i.e. the response times achievable from the grid systems, is reported as not very satisfactory. End users may be forced to purchase, maintain and upgrade their own dedicated HPC systems for the execution of their...
FutureGrid provides novel computing capabilities that enable reproducible experiments while simultaneously supporting dynamic provisioning. This paper describes the FutureGrid experiment management framework to create and execute large scale scientific experiments for researchers around the globe. The experiments executed are performed by the various users of FutureGrid ranging from administrators...
Energy consumption of data centers has been in-creasing continuously during the last years due to rising demands of computational power especially in current Grid- and Cloud-Computing systems. One promising approach of reducing this energy consumption is the consolidation of servers by virtualization. Many low loaded computer systems are virtualized and run on few physical servers for reducing the...
The Biological applications such as Gene and Protein analysis integrate and analyze biological data for the research in many bioinformatics and other bio related fields. Such applications are used under many large scale scientific applications and help in computing, integrating data, execute the analysis, automate the process by using information retrieved by different tasks and computational procedures...
From its start using supercomputers, scientific computing constantly evolved to the next levels such as cluster computing, meta-computing, or computational Grids. Today, Cloud Computing is emerging as the paradigm for the next generation of large-scale scientific computing, eliminating the need of hosting expensive computing hardware. Scientists still have their Grid environments in place and can...
Cloud Computing has taken commercial computing by storm. However, adoption of cloud computing platforms and services by the scientific community is in its infancy as the performance and monetary cost-benefits for scientific applications are not perfectly clear. This is especially true for desktop grids (aka volunteer computing) applications. We compare and contrast the performance and monetary cost-benefits...
The high cost of creating and maintaining software and hardware infrastructures for delivering services to businesses has led to a notable trend toward the use of third-party service providers, which rent out network presence, computation power, and data storage space to clients with infrastructural needs. These third party service providers can act as data stores as well as entire software suites...
Live migration of virtual machine (VM) is a desirable feature for distributed computing such as grid computing and recent cloud computing by facilitating fault tolerance, load balance, and hardware maintenance. Virtual machine monitor (VMM) enforced process protection is a newly advocated approach to provide a trustworthy execution environment for processes running on commodity operating systems.While...
Using remotely located software or hardware resources for solving various technical problems is presently the main subject of the current emerging technologies such as utility computing, cloud computing, Grid computing and so on. This paper discusses a possible architectural solution and describes a platform built bearing in mind the requirements for solving mathematical-described problems, but potentially...
ldquoCloudrdquo computing - a relatively recent term, builds on decades of research in virtualization, distributed computing, utility computing, and more recently networking, web and software services. It implies a service oriented architecture, reduced information technology overhead for the end-user, great flexibility, reduced total cost of ownership, on-demand services and many other things. This...
