Enterprise IT infrastructure incurs many costs ranging from hardware costs and software licenses/maintenance costs to the costs of monitoring, managing, and maintaining IT infrastructure. The recent advent of cloud computing offers some tangible prospects of reducing some of those costs; however, abstractions provided by cloud computing are often inadequate to provide major cost savings across the...
In this work, we present Media-Aware Workflows, an extension to Business Process Management Systems (BPMS) and Service Oriented Architecture (SOA) middleware for automating media workflows. The combination of SOA and BPMS technologies provides a robust architectural approach for integrating and orchestrating the multiple heterogeneous systems involved in enterprise-level workflows. However, media-intensive...
RFID technology finds immense applicability in various domains utilizing identification as the base operation such as in access control, localization, and tracking etc. It may be designed to work satisfactorily for either singular or a limited range of applications. However, the strict-coupling between applications and RFID equipment must be relaxed to scale up their usability. In order to achieve...
For aspect oriented Web service orchestration, there are two major problems, aspect determination and crosscutting base with aspect. Contrary to other researches focusing on implementation, this paper presents an aspect oriented design method, Themes4BPEL. The novelty of this approach is that it includes five rules to differentiate aspect from base with three views analysis. And the test cases for...
With the advent of Web services and SOA (service-oriented architecture), it seems to be feasible to realize EAI (enterprise application integration) and automatic inter-enterprise interactions. This paper combines SOA and Web service technology which simplify the application integration into the development and using of services, solve the connectivity of the isomerous platform, security, and the...
The three-tier architecture pattern and its variants have been around for a while and there are several discussions of their properties as well as several patterns. None of these discussions considers security. However, several real systems implement this approach including security. We revisit this pattern to explicitly separate and analyze its security aspects.
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
Privacy helps to establish personal autonomy and create individualism. Privacy is a state or condition of limited access to a person. In particular, information privacy relates to an individual's right to determine how, when, and to what extent information about the self will be released to another person or to an organization. It can be said that privacy is a much broader concept than security; privacy...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
Many Web services are expected to run with high degree of security and dependability. To achieve this goal, it is essential to use a Web-services compatible framework that tolerates not only crash faults, but Byzantine faults as well, due to the untrusted communication environment in which the Web services operate. In this paper, we describe the design and implementation of such a framework, called...
