According to clause 57.10 of AWS' Terms of Service (http://aws.amazon.com/service-terms/), it is NOT OK to use Lumberyard for life- or safety-critical systems, UNLESS there is a zombie apocalypse:

> 57.10 Acceptable Use; Safety-Critical Systems. Your use of the Lumberyard > Materials must comply with the AWS Acceptable Use Policy. The Lumberyard > Materials are not intended for use with life-critical or safety-critical > systems, such as use in operation of medical equipment, automated > transportation systems, autonomous vehicles, aircraft or air traffic control, > nuclear facilities, manned spacecraft, or military use in connection with live > combat. However, this restriction will not apply in the event of the > occurrence (certified by the United States Centers for Disease Control or > successor body) of a widespread viral infection transmitted via bites or > contact with bodily fluids that causes human corpses to reanimate and seek to > consume living human flesh, blood, brain or nerve tissue and is likely to > result in the fall of organized civilization.
