• Contemporary systems are built from complex arrangements of interoperating components implementing functional and other non-functional concerns that are necessary to ensure continuing service delivery. One of these concerns—resilience—relies on components that implement a variety of mechanisms, such as access controls, adaptability and redundancy. How these mechanisms interoperate with each other and the systems’ functional components to provide resilience is considered in this paper. External consistency, defined as the extent to which data in the system corresponds to its real-world value, provides a natural interpretation for the definition of resilience. A model of resilience is developed that can be used to trace how the functional and non-functional components in a system contribute to the determination of our confidence in the external consistency of the data that they process.
