“…[58] proposes a flexible heuristic provisioning strategy that allocates multiple services for unreliable tasks in order to proactively deal with failures. Finally, [34] presents an example of adaptation based on service tuning, using for this purpose a management interface implemented according to the WSDM standard.…”

“…• service tuning: the behavior and/or properties of the operations of concrete services are changed, depending on the current operating conditions, exploiting some management interface exposed by the concrete services themselves (e.g., based on WSDM MOWS [34]). This kind of action does not change the current binding between tasks and operations of concrete services; • service selection: the goal of this action is to identify and to bind to each task a corresponding single operation offered by a concrete service, selecting it from a set of candidates.…”

Abstract-Architecting software systems according to the serviceoriented paradigm, and designing runtime self-adaptable systems are two relevant research areas in today's software engineering. In this paper we address issues that lie at the intersection of these two important fields. First, we present a characterization of the problem space of self-adaptation for service-oriented systems, thus providing a frame of reference where our and other approaches can be classified. Then, we present MOSES, a methodology and a software tool implementing it to support QoS-driven adaptation of a service-oriented system. It works in a specific region of the identified problem space, corresponding to the scenario where a service-oriented system architected as a composite service needs to sustain a traffic of requests generated by several users. MOSES integrates within a unified framework different adaptation mechanisms. In this way it achieves a greater flexibility in facing various operating environments and the possibly conflicting QoS requirements of several concurrent users. Experimental results obtained with a prototype implementation of MOSES show the effectiveness of the proposed approach.Index Terms-Service-oriented architecture, runtime adaptation, quality of service.

The service-oriented architecture (SOA) is becoming increasingly popular as a paradigm for developing new distributed systems and integrating heterogeneous legacy systems. A service-oriented system (SO system for short) is a group of applications that interact with other(s) by providing and/or consuming services. As the deployments of serviceoriented applications and systems increase, it becomes obvious that systems management is the "Achilles' heel" of these systems. This paper reviews the underlying concepts, principles and technologies related to SO systems management.

“…Dynamic adaptation and self-management of Web services rely on a set of adaptive components, which are composed into control loops for constantly monitoring the system, analyzing the situation and deciding on the actions to affect the system's behavior [13,16]. These adaptive components are generally concerned with quality attributes such as performance or dependability.…”

Composing adaptive and self-managing Web services needs plug-and-play architecture so that the deployment of control components does not require changes made to the Web services and the host middleware platforms. This is especially challenging for Web services running on COTS middleware platforms, such as Microsoft .Net. In this paper, we propose an architectural solution that introduces a management proxy between adaptive control components and Web services. The management proxy can be customized and seamlessly integrated with a COTS middleware platform by leveraging the existing middleware mechanisms. This solution enables dynamically composing adaptive Web services on COTS middleware without stopping its services. We demonstrate this architecture by a realistic Web service application built on .Net Windows Communication Foundation (WCF). The performance overhead incurred by this architecture is measured, and the results validate that our solution is efficient in terms of performance and flexibility.
