This is a short introduction to fault tolerance in the context of scale out solutions. I gave this talk at SEACON 2012 and my biggest problem was to compress a topic that usually needs at least 4 hours down to 45 min. Thus, this just gives a very brief overview and presents a few basic patterns. Nevertheless it should help to get a first idea how fault tolerant design is different from normal enterprise application design we are used to for the last 10 or 15 years.
