Towards a Formal Component Model for the Cloud
Résumé
We consider the problem of deploying and (re)configuring resources in a "cloud" setting, where interconnected software components and services can be deployed on clusters of heterogeneous (virtual) machines that can be created and connected on-the-fly. We introduce the Aeolus component model to capture similar scenarii from realistic cloud deployments, and instrument automated planning of day-to-day activities such as software upgrade planning, service deployment, elastic scaling, etc. We formalize the model and characterize the feasibility and complexity of configuration achievability in Aeolus.
