PAEAN- a risk-mitigation framework for business transaction at run-time

The increasing complexity of the business transaction results in a higher potential risk in terms of SLA violation. The fulfillment of the QoS constraints specified in global SLA can be threatened at any time by different unexpected events that could occur during the execution of a business transaction. Unfortunately, there is no solution found that can efficiently mitigate this risk. Some of the current business transaction monitoring and managing solutions can monitor business transaction and report fault only after it happens. The framework proposed in this paper, monitors business transactions, computes potential risks and performs proactively adaptation actions in order to avoid global SLA violation that could causes transaction abortion.
