As Cloud Computing begins to move beyond the pure hype stage and into the beginning of mainstream adoption, adopting cloud-based services or moving application services to the cloud brings a number of new risks, including: Cloud availability, Cloud security, Erosion of data integrity, and so on. However, for enterprise which require visibility, trust and control over cloud-based services. To maximize...
A System Architecture [SA] plays the leading role in ICT based organization. It covers the entire organization and helps to achieve the mission of organization. As other architectures, it also has set of components and the relationship (connectors) among the components. It has pre-defined life cycle that determines the duration of the system in which it should provide the services continuously. It...
As the number of elderly people increases, so does the need for innovative technology enabling to keep these old persons in their own home, as long as they so desire and as is technically and medically feasible. In the framework of a regional research project we are working on an information system aiming at managing the various processes involved in caring for elderly persons in their home. We present...
The right information at the right time is a critical aspect in any emergency or disaster management activity. Decision making and efficiency are improved when based on complete information about the conditions of the affected area. Sensors integration in a grid-based infrastructure, through a service-oriented architecture and via the World Wide Web, allows for real-time access to information. In...
In the business context, accountability has become a major concern for businesses around the world in aftermath of corporate scandals and fallouts. However, accountability has not been rigorously considered in IT system technologies and solutions. The goal of this study is to provide a clear understanding of accountability concept in service-oriented computing and, more generally, e-society. We first...
We propose SAGE (Service Oriented Architecture Governance Evaluation) as a quantitative approach, to evaluate the impact of SOA governance policies on prominent quality attributes. Our approach facilitates an exhaustive quantitative impact analysis to evaluate the effectiveness of SOA governance policies. This can be further used to estimate the current maturity level of any SOA based enterprise....
Organizations today are required to adhere to a number of compliance concerns from laws, regulations and policies. Compliance is achieved through defining and implementing so-called controls in the organizations' business processes. Organizations that build their systems based on the process-driven SOA paradigm realize business processes through orchestration of services to handle the different process...
Cross-organizational business processes gain more and more attention in the scientific community. For modeling these processes, choreographies are an adequate solution to describe the observable behavior for each business participant and the corresponding protocols between them. Nevertheless, current approaches mainly focus on modeling and conformance checking before runtime. In contrast, this contribution...
This research paper presents a new pattern for the espousal of SOA in small enterprises for the service delivery beyond the typical role of SOA and BPM for dynamic endorsement of the processes beyond the ordinary border-lines. In comparison with large enterprises, the presented framework can expose the fact that the improvements of service orientation and the fruits of process management can be confined...
A new organization based system for oceanographic monitoring (OBSOM) is presented in this paper. The OBSOM core system is based on the case-based reasoning methodology, and it is able to generate a prediction about ocean conditions in certain areas of the ocean. CBR uses historical data to create new solutions to current problems. The system employs a distributed multi-agent architecture so that the...
The use of floating car data is an interesting method to monitor traffic. Vehicles act as local traffic sensors and data from individual vehicles is aggregated into higher-level information. We propose a number of reusable organization abstractions and a software architecture to support a multi-agent approach applied to floating car data. The abstractions are based on the idea of hierarchical organizations...
In this paper, we present a dynamic analysis approach to increase the understandability of a large software-intensive system, more particularly to enable the identification of dependencies between its execution entities. This approach analyzes the execution of a software system in a top-down fashion to cope with complexity and uses execution entities such as scenarios, components, and processes rather...
Considering that each IT-organization is based on an established IT-governance the introduction of SOA as a new overall architectural approach will change the requirements for the specific governance model. The paper presents a SOA-specific governance model which differentiates an operating model, service lifecycle management, service ownership, cost allocation, and meta-data management support. Based...
As service-oriented computing increases, so does the role of e-contracts in helping business partners automate contractual agreements and relationships. The key challenge is to translate traditional contracts into executable e-contracts in a way that facilitates runtime monitoring and management. As research in this area progresses, organizations will have different approaches for modeling, implementing,...
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...
An important issue to the adoption of any enterprise architectural approach is the availability of tools to support the development, storage, presentation, analysis, improvement and evolution of enterprise architecture representations. As with enterprise architecture methodologies, enterprise architecture tools to support the architectural development process are still emerging. Most important software...
