Cloud computing is a recent paradigm in information technology enabling an economic model for virtual resources provisioning. Monitoring remains an important task to efficiently manage the Cloud, but it is still a challenge to find a monitoring solution that reconcile the scalability, the memory consumption, and the efficiency. In this paper, we propose an extension for Service Component Architecture to allow the description of monitoring needs, and a new framework that adds monitoring facilities to components and encapsulates them in a scalable micro-container at deployment time. Unlike the existing initiatives in the state of the art, our framework adds dynamically monitoring facilities to components even if they were not designed to be monitored. This makes the task of developers easier letting them focusing on the business of their components instead of the non functional property of monitoring. Moreover, our framework uses a scalable micro-container for components' 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 of monitoring applications in the Cloud
