Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors. Therefore, before we attempt to measure our database performance, we should know the system or cloud instance to be tested in detail. Operating System: Ubuntu 22.04
