In order to process service failure quickly, a new failure recovery for service supporting context persistence named G-FRF is given, which is based on the existing failure recovery frameworks for Web Services. Failure recovery requirements of manager job services in grid computing are taken into account in the framework. during normal execution, service state is monitored and context is saved. When...
The runtime management of the infrastructure providing service-based systems is a complex task, up to the point where manual operation struggles to be cost effective. As the functionality is provided by a set of dynamically composed distributed services, in order to achieve a management objective multiple operations have to be applied over the distributed elements of the managed infrastructure. Moreover,...
Service Oriented Architectures ease integration of heterogeneous systems, such as sensor data and workflow systems. Systems are integrated since they model an overlapping part of the physical world, i.e., physical objects exchanged between different parties. For workflows handling physical objects, the correlation of sensor data with workflow states and workflow state changes are investigated in this...
Much larger flexibility of software adaptability is necessary to the destination platform and the user requirement in distributed systems. Component-based models are becoming increasingly ubiquitous as enabling technology for modern distributed system applications. Software modules and components have always played a key role in the systems. The fundamental contribution of component-based models lies...
This paper reports a novel semantic web application developed to deliver a collaborative tagging system for a digital on-line museum. The key features of our application - called the Virtual Museum of the Pacific - concern the browsing and retrieval interface based on Formal Concept Analysis the extensible distributed data model to support collaborative tagging and its web services implementation.
This paper describes WappenLite-a Web application framework for lightweight educational programming environments. In particular, this paper focuses on the back-end (nonuser-interface) components of the framework.
Representational State Transfer (ReST) architecture provides a set of constraints that drive design decisions towards architectural properties such as interoperability, evolvability and scalability. Designing a ReSTful service API involves finding resources and their relationships, selecting uniform operations for each resource, and defining data formats for them. It is often a non-trivial exercise...
Message-based debugging facilities for Web or Grid Services are separated from an infrastructure of source level debugging and can work in a self-identifying and coexisting mode within a normal services container. In this paper, we discuss problems for services debugging and approaches we take. We present the operational model and context inspection of message-based debugging facilities. The facilities...
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,...
The increasing interest in Web services has led to a recent proliferation of service-oriented platforms for supporting Scientific Workflows in a variety of e-Science domains. These platforms mainly address the application-specific composition and enactment of workflows. However, since scientific workflows are characterized by complex computations and large volumes of data, non-functional criteria...
Configuration complexity is a novel research field.The concept of configuration complexity is outlined in this paper, as well as current research is introduced briefly. Based on the current study results and best practice, improved configuration complexity quantitative model is proposed in the paper. Then, after an enterprise network environment is constructed in the laboratory, the quantitative model...
