Abstract:
Cloud computing raises many issues about Virtualization and Service-Oriented Architecture (SOA). Topics to be addressed regarding services in Cloud computing environment include contractualization, monitoring, management, and autonomic management. Cloud computing, promotes a "pay-per-use" business model. This business model should enable to reduce costs but requires flexible services than can be adapted to load fluctuations. This work is conducted in the European CELTIC Servery cooperative research project, which deals about a telecommunication services marketplace platform. The Servery project focuses amongst others on the self-scaling capability of Telco services in a cloud environment. The self-scaling capability is achieved thanks to Service Level Agreement (SLA) monitoring and analysis (i.e., compliance checking), and to autonomic reconfiguration performed according to the analysis results. SLAs are defined for the services and for the cloud virtualized environment. In order to achieve this self-scaling capability, a specialized autonomic loop is proposed. Our proposal is well in line with the Monitor, Analyze, Plan, and Execute loop pattern defined by IBM. The proposed solution is based on the following open-source middleware: Service Level Checking, OW2 JASMINe Monitoring, OW2 JASMINe VMM. This paper presents this solution that has been implemented and validated in the context of the Servery project.
