We propose a policy-based framework for the automated establishment of Service Level Agreements (SLAs) in Service Oriented Architecture (SOA) environments such as the cloud. The novelty of our proposed framework is the support for multiple SLA interaction models, giving entities the flexibility to choose the one that is most appropriate in a given context, while simultaneously participating in multiple concurrent SLA interactions using different interaction models. As part of the framework, we
more » ... resent AutoSLAM, a policy based middleware that uses policies described with the use of WS-SLAM, our new WS-Policy extension, that provides a domain-independent policy specification language for specifying conditional assertions over the supported SLA interaction models. We have implemented an AutoSLAM proof-of-concept prototype and evaluated it for purchasing computing resources on Amazon Ee2 under different contexts.
