Computer Science experimental testbeds allow investigators to explore a broad range of different state-of-the-art hardware options, assess scalability of their systems, and provide conditions that allow deep reconfigurability and isolation so that one user does not impact the experiments of another. An experimental testbed is also in a unique position to support methods facilitating experiment analysis and improve repeatability and reproducibility of experiments. Providing these capabilities at least partially within a commodity framework improves the sustainability of systems experiments and thus makes them available to a broader range of experimenters.
