Modeling and analysing operation processes for dependability

Abstract

Application dependability issues depend on increasingly sophisticated activities during operation time for deployment, upgrade, scaling out/in and reactions to various failures. Traditional approaches to improving application dependability focus on artifact-oriented troubleshooting and improvements. In this paper, we present an approach using process models to represent and analyze operations with considerations of exception handlings and fault-proneness. Our goal is to reduce diagnosis and repair time for application failures that occur during operation activities such as deployment and upgrade.
