Applying runtime verification techniques to an enterprise service bus

An Enterprise Service Bus (ESB) integrates remote components creating a distributed system from a centralised location where certain aspects of the system are dynamic in nature. These characteristics give rise to potential runtime issues arising during the deployment of ESB applications. In this paper we describe why some of these issues may not be addressed at compile time; as current ESB solutions go a long way in providing the right tools to setup integration tests which allow for testing the integration logic, however are unable to guarantee correctness beyond the scope of such tests. Due to the characteristics of ESB applications, we discuss applying Runtime Verification (RV) techniques in three separate approaches over an ESB with the goal of giving a correctness guarantee for problems undetectable at compile-time with the aim of minimising performance impacts inhibited on the ESB system.
