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.
