We propose Hogna, a platform for deploying self-managing web applications on cloud. The platform enables the deployment of the applications based on the automation of a set of operations (starting instances, installing necessary software and configuring the instances, etc.), and then the continuous monitoring of the health of the applications. The gathered monitoring data is analyzed using a performance model and an action plan is created and executed. Any components involved (for monitoring, analyzing, planning and deployment changes) can be customized to fit the needs of the application and/or researcher.
