Dependable Systems (2011)Summer 2011
Oral exams: 22.8.-24.8. , 19.9.-21.9.
Continous service provisioning is a key feature of modern hardware und software server systems. These systems achieve their level of user-perceived availability through a set of formal and technical approaches, commonly summarized under the term dependability.
Dependability is defined as the trustworthiness of hardware and software systems, so that reliance can be placed on the service they provide. The main dependability attributes commonly known and accepted are availability, reliability, safety, and security.
The Dependable Systems course gives an introduction into theoretical foundations, common building blocks and example implementations for dependable IT components and systems. The focus is on reliability and availability aspects of dependable systems, such as reliability analysis, fault tolerance, fault models or failure prediction. Amongst other things, the following topics are covered:
- Dependability definitions and metrics
- Design patterns for fault tolerance
- Analytical evaluation of system dependability
- Hardware dependability approaches
- Software dependability approaches
- Latest research topics
Students taking this course need to have basic knowledge in operating systems and middleware technology. On request of at least one participant, the course will be given in English. The course contains of two modules: Lectures and assignments. The pass-grading for 2 out of 3 assignments is the mandatory precondition for taking the oral exam. The final course grade is the oral exam grade.

AssignmentsThe solution submission system demands authentication with either a valid DFN or HPI certificate. The later can be automatically generated at the HPI Certificate Authority (CA). You need to use your HPI account credentials to enter the page. The generated user certificate is automatically installed in your browser - make sure that you export and re-import it if you want to access the submission system from another browser product.
