Automated Negotiation Among Web Services

Software as a service is well accepted software deployment and distribution model that is grown exponentially in the last few years. One of the biggest benefits of SaaS is the automated composition of these services in a composite system. It allows users to automatically find and bind these services, as to maximize the productivity of their composed systems, meeting both functional and non-functional requirements. In this paper we present a framework for modeling the dependency relationship of different Quality of Service parameters of a component service. Our proposed approach considers the different invocation patterns of component services in the system and models the dependency relationship for optimum values of these QoS parameters. We present a service composition framework that models the dependency relations ship among component services and uses the global QoS for service selection

Optimizing Data Processing Service Compositions Using SLA's

International audienceThis paper proposes an approach for optimally accessing data by coordinating services according to Service Level Agreements (SLA) for answering queries. We assume that services produce spatio-temporal data through Application Programming Interfaces (API's). Services produce data periodically and in batch. Assuming that there is no full-fledged DBMS providing data management functions, query evaluation (continuous, recurrent or batch) is done through reliable service coordinations guided by SLAs. Service coordinations are optimized for reducing economic, energy and time costs

Dispute Resolution for Cloud Services: Access to Justice and Fairness in Cloud-Based Low-Value Online Services

The traditional concepts of practicing the law do not follow the pace of the development of the new technologies. Faced with inefficiency and ineffectiveness of the courts regulators are constantly looking into alternatives to increase access to justice and improve efficiency of the dispute resolution mechanisms. The EU has recently enacted ADR and ODR regulations for consumer cross-border disputes. At the same time, we have witnessed parallel attempts from several public bodies and international organisations to introduce the legal framework for the resolution disputes coming out of online transactions. These proposals are in principle focusing on e-commerce aspects of dealing with low-cost consumer/seller disputes. The development of cloud computing services, as a form of e-commerce last decade, raised new issues of applicable law, jurisdiction, access to justice, the legal nature of the disputes, consumer protection etc. To obtain cloud computing services users generally accept a predefined contract of adhesion, where the terms should be accepted on “as is” basis. Non-negotiable predefined terms often tend to be in favor of providers. This research answers do the currently available dispute resolution mechanisms provide adequate means to resolve cross-border low-value disputes between cloud providers and users, and if not, what legal measures can be taken to improve access to justice and fairness in this domain
