Distributed enterprise systems consist of a collection of interlinked services and components that exchange information to collectively implement functionality in support of (sometimes mission critical) workflows. Systematic experimental testing and continuous runtime monitoring of these large scale distributed systems, including event interpretation and aggregation, are key to ensuring that the system’s implementation functions as expected and that its security is not compromised.
