• We propose an autonomic management model for Cloud resources.
• We extend Open puting Interface to describe our autonomic model.
• We illustrate our autonomic model with an approach for Business Processes elasticity.
• We propose a formal approach for Business Processes elasticity.
• We show the efficiency of our approach on a realistic Cloud environment.
