A Layered Framework for Connecting Client Objectives and Resource Capabilities

entifies three levels of abstraction for resource requirements a service provider needs to manage, detailed specification of raw resources, virtualization of heterogeneous resources as abstract resources, and performance objectives at an application level. The paper also identifies three key functions ging service-level agreements, namely: translation of resource requirements across abstraction layers, arbitration in allocating resources to client requests, and aggregation and allocation of resources from multiple lower-level resource managers. One or more of these key functions may be present at each ion layer of a service-level manager. Thus, layering and the composition of these functions across ion layers enables modeling of a wide array of management scenarios. The framework we present uses service metadata and/or service performance models to map client requirements to resource capabilities, uses business value associated with objectives to arbitrate between competing requests, a...
