The Art of Fault Injection

Abstract

In this paper we relate the foremost virtues of temperance, justice, courage, and prudence to the correct methodological approaches that researchers should follow when setting up a fault injection experiment. With this work we try to understand where good and bad practices lie, in order to highlight those common methodological errors that deeply influence the coherency and the meaningfulness of fault injection experiments. Fault injection is like an art, where the success of the experiments depends on a very delicate balance between modeling, creativity, statistics, and patience.
