In a cloud computing environment, resources are shared among different clients. Intelligently managing and allocating resources among various clients is important for system providers, whose business model relies on managing the infrastructure resources in a cost-effective manner while satisfying the client service level agreements (SLAs). In this paper, we address the issue of how to intelligently...
The world economy continues to evolve away from the traditional producer-consumer roles prevalent in the industrial era, towards more dynamical, collaborative business relationships characteristic of the emerging global services economy. New challenges are emerging for businesses engaged in service delivery, particularly concerning process normalization and cost estimation. Service standardization...
We focus on dynamic monitoring of security and privacy policies in service oriented architectures (SOAs) based systems. In a service oriented system both the internal and the external services may easily interact with each other, which makes the establishment and the enforcement of the privacy policies and the rules across the systems increasingly challenging. We introduce efficient and flexible methods...
In computer science, anti-patterns are specific repeated practices that appear initially to be beneficial, but ultimately result in undesirable consequences that outweigh the expected advantages. In this article we present our experiences from a range of industrial projects where there is a strong need for integrating distributed and heterogeneous data sources. SOA approach is selected to achieve...
In a service oriented system both the internal and the external services may easily interact with each other, which may make the establishment and the enforcement of the privacy policies and the rules across the systems increasingly challenging. In this paper we present our ongoing system architecture and implementation work to enable efficient and flexible methods for auditing such systems by leveraging...
In this paper, we present some of our experiences from the architectural design phase of business information analysis service provisioning system, BISON. More specifically we discuss the issues, challenges, and our solution approaches to asynchronously scheduling the service requests in an optimal manner to enhance the user experience in the system
