Abstract:
With the commoditization of cloud computing, more and more companies prefer to outsource IT resources into virtual infrastructures. Service Level Agreements (SLAs) can be helpful to make the right investment decision. A SLA template represents the pre-agreed SLA state. A service provider proposes the SLA content and submits the template to a marketplace for customer consideration. Customers use SLA template views as ”What You See Is What You Get” (WYSIWIG) snapshots prior to service selection and before agreement initialization. The paper proposes a filtering frame- work that is based on a faceted approach and that uses SLA templates to guide marketplace customers through available services. The framework design is presented along with the data-model of SLA templates. We report the results from testing the faceted filtering with two different SLA storage approaches and evaluate their appropriateness for the web application layer.
