Framework of Software Performability Modeling,When compared with model-based evaluations that concern the effects of operational faults in hardware, the nature and needs of software performability modeling differ in several respects.

General Concepts and Applications of Performability Modeling, via measurements of an actual system. The review that follows presumes the former, permitting us to be more precise in the statements of key concepts. Except for small changes in some of the notation and terminology, it summarizes the original framework described in [5, 6].

Case Study III: Performability Management in Distributed Database Systems,ly, there is always a latency between the time when the information about remote sites is collected and the time when an adaptive decision is made, which may make the adaptation ineffective since the information (based on which the adaptive decision is made) could become obsolete through the latency.
