To solve the problem of service failure for job management services, a new failure recovery Framework named J-FRF is given. During the life cycle of service and job, states are monitored and contexts are saved. When service failure occurs, the framework takes advantage of the persistent contexts to realize rapid recovery of service and job. The experiments show that J-FRF has a high recovery success...
Trust has been recognized as important factor for Grid computing security. Trust is the degree of belief in the resource provider's competence to complete user's task dependably, securely and reliably in a specific context at a given time. In this paper, we propose the trust model in Grid system. It consists of Application Domain (AD), Client Domain (CD), Resource Domain (RD), and Trust Manager (TM)...
The emergence of the Internet has changed the nature of face-to-face towards online interactions. This leads to the concept of virtual interoperation such as Web Services, Grid, and Cloud Computing. Since existing security mechanisms are insufficient to cover the diversity of workflow application domains, trust is considered as an adaptive, high-level abstraction, and platform-independent solution...
This paper describes an approach to the formulation and classification of security requirements in eScience. It explains why it is untenable to suggest that `one size fits all', and that what is an appropriate security solution in one context may not be at all appropriate in another. It proposes a framework for the description of eScience security in a number of different dimensions, in terms of measures...
Service Oriented Infrastructures including Grid and Cloud Computing are technologies in a critical transition to wider adoption by business. Their use may enable enterprises to achieve optimal IT utilization, including sharing re-sources and services across-enterprises and on-demand utilization of those made available by business partners over the network. This paper presents a selection of common...
Modern e-Science and high technology industry require high-performance and complicated network and computer infrastructure to support distributed collaborating groups of researchers and applications that should be provisioned on-demand. The effective use and management of the dynamically provisioned services can be achieved by using the Service Delivery Framework (SDF) proposed by TeleManagement Forum...
The DynaSOAr framework presents a wholly service-oriented approach to grid and Internet-based computing that makes a clear and explicit separation of concerns between service-provision and resource-provision for each service invocation. The separation allows the dynamic deployment of code at runtime, in the form of a service implementation, between a service provider and an explicit resource provider...
At present most of the reputation models haven't consider enough about the context of the entities 's conduct, no define and no evaluate about the multi-act properties. In responding these issues, referencing on the trust relationship of society and introducing the multi-service properties, we propose a grid reputation model based on service quality. According to its own characteristics, the service...
Event-drive business processes require integration with distributed heterogeneous services to fulfill the functionalities. Business processes run in parallel and interact with multiple services, partners and customers as per the requirement and policy. There is a need to aggregate information from multiple resources or services according to policy. Resource or service aggregation provides better query,...
The heterogeneity of Grid resources (e.g. compute, storage, and network) that are geographically dispersed creates a fundamental challenge in terms of their discovery and monitoring process in production Grids today. In order to overcome these challenges, a wide variety of information models and services are developed that provide proprietary solutions in rather complex ways. Many of those services...
Web service models are increasingly being used in the Grid community as way to create distributed applications exposing data and/or applications through self describing interfaces. Scientific research is one key field in which the benefits are apparent as individual services can be orchestrated into experimental workflows that model the research process and facilitate verification and extension. However,...
Acknowledged as important factors for business environments operating as virtual organizations (VOs), trust and reputation are receiving attention also in Grids devoted to scientific applications where problems of finding suitable models and architectures for flexible security management of heterogeneous resources arise. Being these resources highly heterogeneous (from individual users to whole organizations...
Delegation is a key facility in dynamic, distributed and collaborative environments like Grids and enables an effective use of a wide range of dynamic applications. Traditional delegation frameworks approach a top-down model of delegation for delegating rights from a superior to a subordinate in advance before a delegate starts off a delegated task. However, a top-down model of delegation cannot meet...
