Load Testing Elasticity and Performance Isolation in Shared Execution Environments


Samuel Kounev (University of Würzburg)


The inability to provide performance guarantees is a major challenge for the widespread adoption of shared execution environments, based on paradigms such as virtualization and cloud computing. Performance is a major distinguishing factor between different service offerings. To make such offerings comparable, novel metrics and techniques are needed allowing to measure and quantify the performance of shared execution environments under load, e.g., public cloud or general virtualized service infrastructures. In this talk, we first discuss the inherent challenges of providing performance guarantees in the presence of highly variable workloads and load spikes. We then present novel metrics and techniques for shared execution environments, specifically considering the dynamics of modern service infrastructures.
