Application services run on a computing platform and consume platform services. Performance measurement units are defined for the application services. A number of relationships for consumption of resources are defined between one or more of the application services and one or more of the platform service. Performance tests are executed on an application service while consuming different capacities provided by one or more instances of consumed platform services. Results measuring performance of the application service during test executions are collected. Based on the collected results, scaling formulas are determined for each of the consumed platform services by the application service. A scaling formula defines a correspondence between a capacity provided by a first consumed platform service and measured performance of the application service. Based on the scaling formulas, required capacities of the consumed platform services may be determined with respect to a predefined performance of the application service.
