It's more broad than what's been suggested so far, but it seems bang on from my POV; "Reliability, within the perspective of application architectures, can be viewed as the degree to which an architecture is susceptible to failure at the system level in the presence of partial failures within components, connectors, or data. Styles can improve reliability by avoiding single points of failure, enabling redundancy, allowing monitoring, or reducing the scope of failure to a recoverable action." -- http://www.ics.uci.edu/~fielding/pubs/dissertation/net_app_arch.htm#sec_2_3_7 MB -- Mark Baker.
