摘要

We present a reliability certification scheme in which services are modeled as discrete-time Markov chains. A machine-readable certificate is issued to the service after validating its reliability properties, and validity of the certificate is verified using constant run-time monitoring. In addition, we present a solution that allows users to search and select services with a given set of reliability properties. Our solution is integrated within existing Service-Oriented Architectures (SOAs), and allows validation of users' preferences both at discovery-time and at run-time.
