Chaos engineering is the discipline of testing distributed software or systems by introducing failures and permitting engineers to study the demeanor and perform modifications with the outcome so that the failures are avoided when end users work with the software and systems. It is blended with Site Reliability Engineering (SRE), which attempts to compute the influence of the improbable.

In chaos engineering, practitioners intentionally inject failure into a system to assess its resiliency. This science involves the implementation of experiments and hypotheses followed by comparing the outcome with a steady state.
