Runtime Prediction of Software Service Availability
نویسندگان
چکیده
This paper presents a prediction model for software service availability measured by the mean-time-to-repair (MTTR) and mean-time-to-failure (MTTF) of a service. The prediction model is based on the experimental identification of probability distribution functions for variables that affect MTTR/MTTF and has been implemented using a framework that we have developed to support monitoring and prediction of quality-of-service properties, called EVEREST+. An initial experimental evaluation of the model is presented in the paper.

Preventing Key Performance Indicators Violations Based on Proactive Runtime Adaptation in Service Oriented Environment
Key Performance Indicator (KPI) is a type of performance measurement that evaluates the success of an organization or a partial activity in which it engages. If during the running process instance the monitoring results show that the KPIs do not reach their target values, then the influential factors should be identified, and the appropriate adaptation strategies should be performed to prevent ...

Web services as independent software components are published on the Internet by service providers and services are then called by users’ request. However, in many cases, no service alone can be found in the service repository that could satisfy the applicant satisfaction. Service composition provides new components by using an interactive model to accelerate the programs. Prior to service comp...
