This talk will present the basic design principles for building resilient systems. Starting at the basics from different science areas, we derive a set of principles needed for building resilient computer systems. We will see that building such systems requires some significant changes in the way how we design and operate software systems, but doing so will create robust, scalable and even self-healing systems. Finally we will also do short check on the frameworks and solutions currently available in the Java eco-system to see, what helps building such systems efficiently (and where also things do not match well).
