In recent years, trust has emerged with the development of cloud computing. It is a critical step to select a trusted cloud provider before the service begins, which is related to the interests of cloud consumers themselves and the quality of the service. A SLA trust model based on behavior evaluation is proposed in this paper. User's subjective evaluations are abandoned, the provider who is trusted...
One of the primary requirements in many cyber-physical systems (CPS) is that the sensor data derived from the physical world should be disseminated in a timely and reliable manner to all interested collaborative entities. However, providing reliable and timely data dissemination services is especially challenging for CPS since they often operate in highly unpredictable environments. Existing network...
Applications are increasingly composed of remote services provided by independent parties. This distributed ownership makes it problematic to measure and control quality of service indicators. Management activities must become an integral part of the system's development process, from requirements elicitation, where users identify the quality dimensions of interest, to the implementation, where the...
This paper describes a benchmarking workload model for business process execution language (BPEL) engines for Web services. The proposed model is based on simulation of real world traffic conditions by defining a set of requirements which best characterize the end-users. The performance characteristics are evaluated on top of collected measurements such as success/fail rate, response times or round-trip...
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...
