Comparing of Cloud Computing and Grid Computing

As the current hot technology, many large companies have launched their own cloud computing projects, and the ways to realize each project is different, and ultimately lead to a fragmented state to explain the concept of cloud computing today. Almost all manufacturers do not deny that cloud computing is follow-up and development of grid computing, but their philosophy is different. This article aims to explore the similarities and differences between grid computing and cloud computing, from features, technology and operation costs, and to explore the solution of technical problems related to outstanding solutions through grid technology in the development of cloud computing.

A Cross-Domain Alliance Authentication Scheme based on Bilinear Group

With the development of grid computing, cloud computing and other large distributed network technology, users need them to provide services of unlimited space and unlimited speed. In order to meeting this request of users, all the domains in these large distributed networks need coordination for each other. For ensuring the safety to access resources in all domains, we propose a cross- domain union authentication scheme. We compute a large prime cyclic group by elliptic curve, and use the direct decomposition of this group to decompose automorphism groups ,and design an signcryption scheme between domains by bilinear of automorphism group to achieve cross-domain union authentication. This scheme overcome the complexity of certificate transmission and bottlenecks in the scheme of PKI-based, and it can trace the entities and supports two-way entities anonymous authentication, which avoid the domain certificate authority counterfeiting its member to access cross-domain res ources. Analyses show that its advantages on security and communication-consumption.

Anticipating intended users: prospective sensemaking in technology development

How do developers and designers of a new technology make sense of intended users? The critical groundwork for user-centred technology development begins not by involving actual users’ exposure to the technological artefact but much earlier, with designers’ and developers’ vision of future users. Thus, anticipating intended users is critical to technology uptake. We conceptualise the anticipation of intended users as a form of prospective sensemaking in technology development. Employing a narrative analytical approach and drawing on four key communities in the development of Grid computing, we reconstruct how each community anticipated the intended Grid user. Based on our findings, we conceptualise user anticipation in terms of two key dimensions, namely the intended possibility to inscribe user needs into the technological artefact as well as the intended scope of the application domain. In turn, these dimensions allow us to develop an initial typology of intended user concepts that in turn might provide a key building bloc towards a generic typology of intended users.

Improvement of Job Scheduling and Tow Level Data Replication Strategies in Data Grid

With the development of grid computing, Data Grid, as an important branch of Grid Computing focuses on supporting an efficient management mechanism for controlled sharing and large amounts of distributed data. Data intensive jobs are one major kind of jobs in Data Grid, and their scheduling strategies are regarded as one of the most important research fields. Dynamic replication in data grid aims to reduce data access time and to utilize network and storage resources efficiently. This paper proposes a novel dynamic replication strategy, called ERS(Enhancement of Replication Strategy), which reduces data access time by avoiding network congestions in a data grid network and we develop a job scheduling policy, called ESS (Enhancement of Scheduling strategy).

Security services architecture for Secure Mobile Grid Systems

Mobile Grid, is a full inheritor of the Grid with the additional feature that it supports mobile users and resources. Security is an important aspect in Grid based systems, and it is more complex to ensure this in a mobile platform owing to the limitations of resources in these devices. A Grid infrastructure that supports the participation of mobile nodes and incorporates security aspects will thus play a significant role in the development of Grid computing. The idea of developing software through systematic development processes to improve software quality is not new. However, many information systems such as those of Grid Computing are still not developed through methodologies which have been adapted to their most differentiating features. The lack of adequate development methods for this kind of systems in which security is taken into account has encouraged us to build a methodology to develop them, offering a detailed guide for their analysis, design and implementation. It is important to use software V&V techniques, according to IEEE Std. 1012 for Software Verification and Validation, to ensure that a software system meets the operational needs of the user. This ensures that the requirements for the system are correct, complete, and consistent, and that the life-cycle products correctly design and implement system requirements. This paper shows part of a development process that we are elaborating for the construction of information systems based on Grid Computing, which are highly dependent on mobile devices in which security plays a highly important role. In the design activity of the process, we design a security architecture which serves as a reference for any mobile Grid application that we wish to build since this security architecture defines a complete set of security services which will be instantiated depending on the requirements and features found in previous activities of the process. A V&V task is also defined in the design activity to validate and verify both the architecture built and the traceability of the artifacts generated in this activity. In this paper, we will present the service-oriented security architecture for Mobile Grid Systems which considers all possible security services that may be required for any mobile Grid application.

D2UIGP: A Development Work for the User Interface Design in Grid Portals

Nowadays when we talk about Grid computing, it is important to emphasize the importance that it is having on the development various human areas, but it is also important to mention Grid portals and the impact these are having on the development of Grid computing, at serving as support in researches using this technology. In this paper, we present an overview of the importance of Grid portals and outstanding points will be announced on the use of HCI to the design of these portals, taking in consideration the usability that these must have.

GRID COMPUTING AND DISCLOSURE CONTROL

A grid is a distributed network of computers that can be used as a single information and computational resource for multiple datasets and sources. One of the key challenges of grid computing is that information in different datasets and different types of data such as text and image are likely to have different levels of sensitivity, disclosure risk and terms of use. This paper provides an overview of the development of grid computing and an examination of the disclosure risks poses. The research, funded under the Economic and Social Research Council's (ESRC) e-Social Science Programme, specifically examined the development of grid computing in social science and the work of the e-Social Science grid pilot projects. The paper concludes that while a number of innovative grid enablement projects are in development there has only been a limited assessment of the additional disclosure risks grid computing may pose. The incorporation of effective confidentiality and disclosure control systems will be central in encouraging data holders to share their data and computational resources.

Preface

Grid computing is currently an area of intense activity involving a large community of researchers, developers, and users. Hundreds of experimental and production grids are in operation throughout the world. The development of grid computing has followed a path similar to the development of the World Wide Web, which started as a technology for scientific collaboration but was later adopted for use by a multitude of industries and businesses. Recent standards activities driven by the Global Grid Forum (GGF) have led to the definition of the Open Grid Services Architecture (OGSA), which has met with wide acceptance and is being implemented in commercial grid products.
