Reputation mechanism is critical for a distributed service environment. A customer can select the optimal services to compose a value-added composite service based on services' reputation values. After executing (either successfully or unsuccessfully) a composite service, a customer gives a feedback to the composite service. Then the composite service needs to propagate perception of customer's feedback...
Cloud computing has been a hot topic in the research community since 2007. In cloud computing, the online services are conducted to be pay-as-you-use. Service customers need not be in a long term contract with service providers. Service level agreements (SLAs) are agreements signed between a service provider and another party such as a service consumer, broker agent, or monitoring agent. Because cloud...
In modern service economies, service provisioning needs to be regulated by complex SLA hierarchies among providers of heterogeneous services, defined at the business, software, and infrastructure layers. Starting from the SLA Management framework defined in the SLA@SOI EU FP7 Integrated Project, we focus on the relationship between establishment and monitoring of such SLAs, showing how the two processes...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
In this paper we discuss the use cases for monitoring of Web services for compliance with policies and service level agreements. In particular, the quality of service associated with Web service interactions and its monitoring rely on the proper use by both parties of related Web service protocols. This monitoring is best served by an event-centric model and an extensible scripting language, such...
