Abstract :
The paper presents an approach to dependability analysis of an information system based on interdependent services. The analyzed system consists of autonomous cells of servers that react automatically to detected events (component failures and security incidents). These local reactions cause disruptions in the global workflow, which is then restored by system reconfiguration at higher levels of system management. The dependability analysis is based on the construction of system reconfiguration graph and evaluation of the service availability.
