Abstract
Abstract — Due to the dynamic nature of the Cloud, continuous monitoring of QoS requirements is necessary to manage the Cloud computing environment and enforce service level agreements. In this paper, we propose a QoS monitoring framework for composite Web services implemented using the BPEL process and deployed in the Cloud environment. The proposed framework is composed of three basic modules to: collect low and high level information, analyze the collected information, and take corrective actions when SLA violations are detected. This framework provides for a monitoring approach that modifies neither the server nor the client implementation. In addition, its monitoring approach is based on composition patterns to compute elementary QoS metrics for the composed Web service. In this paper, we illustrate our framework for the response time QoS requirement. Keywords- Monitoring of Web service composition; Cloud environment; Service Level Agreement; SLA violation
