Abstract: Using Virtual Machines from public cloud providers, researchers gain access to a large pool of experimental infrastructure at comparatively low cost. However, as it is shown in this position paper based on dedicated experiments using real-life systems, Virtual Machines often do not provide accurate time measurements. These limitations are problematic for a variety of use cases, such as the runtime comparison of algorithms in the computer science domain.
