Methods, apparatus, products are disclosed for providing policy-based application services to an application running on a computing system. The computing system includes at least one compute node. The compute node includes an application and a plurality of application services of a service type. Providing policy-based application services to an application running on a computing system includes establishing, on the compute node, a service policy specifying one of the application services of the service type for use by the application, establishing a performance ruleset, the performance ruleset specifying rules for analyzing the performance of the computing system, measuring performance of the computing system, and adjusting the service policy in dependence upon the performance ruleset and the measured performance. Providing policy-based application services to an application running on a computing system may also include accessing, by the application, the specified application service.
