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...
Resource provision within critical friend environment take place on a demand fashion and it is based on the aptitude of members to look across multiple locations for resource discovery and allocation. A major concern of such large scale and uncertain topology setting is the capability of members (nodes) to efficiently search and locate neighbouring participants. Here we adopt a Peer to Peer (P2P)...
In this paper we discuss how a Cloud Computing offering can co-exist in the GARUDA infrastructure. GARUDA is now an established Grid, having undergone two phases of evolution. Providing Cloud Computing support is essential to increase the outreach of Grid to more application developers and users. Grids may rely on private networks, whereas Clouds rely on Internet and the Service-oriented Architecture...
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...
Much work is underway within the broad next generation technologies community on issues associated with the development of services to foster collaboration via the integration of distributed and heterogeneous data systems and technologies. Various technology-driven paradigms have emerged, including Web Services, Web 2.0, Pervasive, Grids and Cloud Computing. Recently, some new paradigms have emerged,...
During the past few years much effort has been put into developing community-based methods to capture and analyse a large amount of data in a systematic manner. The concept of crowd-sourcing (also known as citizen science) becomes quite popular. This is mainly due to its distributed service orientation and its group intelligence problem solving production model. Parallel to this emerging technology,...
The Internet offers an enormous potential for all kinds of services, from Web search to online shopping, from social networks to multi-player online games,from online auctions to online encyclopedias. Many of these services thrive due to a vibrant community support. Making services open to community support offers great potentials but makes them also vulnerable to malicious behavior. Malicious behavior...
Next Generation Networks, including specialized implementations such as Cloud Computing and Smart Grids, must be significantly more robust than today's networks - with “baked in” capabilities supporting an array of assurance and cybersecurity capabilities. One of the most significant emerging means of achieving these capabilities is by applying an ensemble of new specifications being developed under...
Utility grids such as the Amazon EC2 cloud and Amazon S3 offer computational and storage resources that can be used on-demand for a fee by compute and data-intensive applications. The cost of running an application on such a cloud depends on the compute, storage and communication resources it will provision and consume. Different execution plans of the same application may result in significantly...
