One important way that an architecture impacts fault tolerance is by making it easy or hard to implement measures that improve fault tolerance. Many such measures are described as fault tolerance tactics. We studied how various fault tolerance tactics can be implemented in the best-known architecture patterns. This shows that certain patterns are better suited to implementing fault tolerance tactics than others, and that certain alternate tactics are better matches than others for a given pattern. System architects can use this data to help select architecture patterns and tactics for reliable systems.
In REF Harrison and Avgeriou studied how several fault-tolerant techniques can be carried out as best-known architectural patterns.
