A software system is dependable if it delivers its service in a way that can be trusted. Software dependability is gaining importance, as software is becoming ubiquituous in our lives and at the same time increasingly complex. Modern software systems are not only growing in size, but also gaining complexity due to additional layers of abstraction, interaction with different components, concurrency and other sources of nondeterminism. This lecture introduces the state of the art of software dependability means, with a strong practical focus on case studies and real-world large scale software systems. Topics covered include:
  • Software Fault, Timing, and Consistency Models
  • Fault Prevention
    • Processes for dependable software design
    • Development practices
  • Fault Tolerance
    • Patterns for fault tolerance and detection
    • Distributed systems: theory and applications
    • Fault tolerance in operating systems
  • Fault Removal and Forecasting
    • Formal methods
    • Testing and Debugging
  • Fault Forecasting
    • Fault injection
    • Dependability modelling and analysis
  • Discussion of Case Studies and Postmortems from Practice

Large parts of the time are spent on practical project work in small teams. Within a coding project, sudents will make an application fault-tolerant and subsequently evaluate it by implementing fault injection. The hands-on project work will be designed as a competition and span the entire semester (details tba).
