Abstract

Dynamic workflow applications are increasingly used in many enterprises to satisfy the variable enterprise requirements. Cloud computing has gained a particular attention to run these applications. However, due to lack of formal description of the resource perspective, the behavior of Cloud resource allocation cannot be correctly managed. This paper fills this gap by proposing a formal model which verifies the correctness of dynamic workflow changes in a Cloud environment using the Event-B method. Our model considers properties related to control flow, data flow and resource perspectives. It aims to preserve the correctness of workflow properties at both design time and runtime.
