Robust management of trans-cloud applications

The fault handling and recovery from runtime failures of cloud applications should be done by taking into account the inter-dependencies occurring among their components, and by dealing with the diverse and heterogeneous cloud offerings used to host them. The latter is even harder in trans-cloud scenarios, i.e., when application components are possibly deployed on different platforms and at different service levels (IaaS or PaaS). In this paper, we propose a methodology to support the automated management and recovery of (un) foreseen failures in a trans-cloud application, which takes into account all interdependencies occurring among its components. We then present a prototype implementation of our proposal, consisting of an orchestrator that exploits a management framework for trans-cloud application deployments, together with management protocols for the automated planning of the fault-aware administration of applications.
