Adding monitoring and reconfiguration facilities for service-based applications in the cloud

Cloud computing is a recent paradigm in information technology enabling an economic model for virtual resources provisioning. For this paradigm, service oriented Architecture (SOA) is a pillar block to build applications. To efficiently manage service-based applications in the cloud, monitoring and reconfiguration remain important tasks but it is still a challenge to find a solution that reconciles the scalability, the memory consumption, and the efficiency. In this paper, we propose a framework that adds monitoring and reconfiguration facilities to services of a service-based application and deploys them in the cloud using a scalable micro-container. Unlike the existing initiatives, our framework adds dynamically these facilities to services that were not designed to be monitored or reconfigured. This makes the developers' task easier, letting them focusing on the business of their services instead of the non functional property of monitoring and reconfiguration. Moreover, our framework uses a scalable micro-container for services' deployment in the cloud to be inline with the scalability of this environment. The evaluation that we performed proves the efficiency and the flexibility of our approach for service-based applications in the cloud.
