With the growing adoption of the Service Oriented Architecture (SOA) in the industry and the wide deployment of Web services, users are increasingly requiring services that are capable of meeting their quality -of-service (QoS) requirements. In this paper, we propose a novel framework for QoS-aware Web service provisioning, which relies on QoS brokers, to mediate between clients and service providers, and a QoS Notification Broker that implements a publish/subscribe model to handle notifications on significant changes in QoS offerings. Furthermore, we describe a multi-attributes algorithm for the selection of potential service providers that can fulfill clients' requests. The algorithm calculates the utility value of each service provider, per Web service type, based on the client QoS requirements. One of the advantages of the approach is that service providers may provide several service types. These services may be simple Web services or composite Web services aggregated from other services. The publish/subscribe model allows QoS brokers to be aware of significant changes in the QoS offerings of service providers; and consequently, be able to make informed selection decisions. Besides, the proposed selection algorithm allows ranking service providers by matching their up-to-date QoS offers against the QoS required by the client.

“…A service is also self-contained, may be composed of other services, and appears to be a "black box" to its consumers [2]. By such SOA guarantees flexibility and adaptability, which are fundamental characteristics of modern business requirements by enabling services to be dynamically selected and composed [3].…”

Abstract. In order to secure collaborative business processes, we present a methodological approach that early integrates security and risk management throughout the design process of service-oriented architectures. We develop our methodology based on two complementary axes: the first being the business needs while the second, is ensuring a consistent security between partners at the runtime. The information security is globally applied to business needs, service specifications and infrastructure deployment. Finally, we annotate services with security parameters that could be used to improve the selection of secure services in run-time.

“…However, they model QoS metrics syntactically, which is poor and not extensible [15], and cannot solve the heterogeneity problem. In this matter, it is required a mutual agreement on the service(s) functional and non-functional properties [21] [22] [23] to develop a method for automatically matching the offers and the requests [22].…”

“…However, these solutions are not backward compatible, and demand providers to change their service offer descriptions. In addition, Oldham et al [22] and Chaari et al [23] propose the definition of QoS metrics inside standards to manage non-functional aspects of WS-Agreement [18] and WS-Policy [19] respectively, so that, they do not modify current service descriptions. Although, they introduce semantic annotations inside the standards, they extend their standards XML schemas, being alternatives not backward compatible.…”

Abstract. The increasing number of functionally similar services requires the existence of a non-functional properties selection process based on the Quality of Service (QoS). Thus, in this article, authors focus on the provision of a QoS model, an architecture and an implementation which enhance the selection process by the annotation of Service Level Agreement (SLA) templates with semantic QoS metrics. This QoS model is composed by a specification for annotating SLA templates files, a QoS conceptual model formed as a QoS ontology and selection algorithm. This approach, which is backward compatible, provides interoperability among customer-providers and a lightweight alternative. Finally, its applicability and benefits are shown by using examples of Infrastructure services.
