Service-oriented architectures enable an environment
where businesses can expose services for use by their
collaborators and their peer organizations. In such an
environment, organizations may have long-standing
cooperative agreements representing the existing services
that they share. Furthermore, they may have service level
agreements (SLAs) that assure the quality of service
standards of the existing services. In an ad-hoc workflow
scenario, a business may need to perform real-time
composition of the existing services in response to
consumer requests. In this work, we suggest that, in
parallel to traditional web service composition, the
business must also compose the corresponding SLAs of
the chosen services to generate a guaranteed service level
to the consumer. In this paper, we introduce a process for
composing SLAs associated with a workflow of web
services. This process results in the discovery of the best
composite (i.e. workflow) capability while optimizing the
underlying service-level attributes.
