A selecting apparatus configured to select out of a set of content distribution network (CDN) entities a CDN entity for distributing content to a client device is described. Content distribution by a CDN entity is associated with a resource consumption, for example in regard of processing load. The selecting apparatus is configured to receive service performance reports for multiple CDN entities of the set of CDN entities and to select, upon determining from one or more of the service performance reports that a service performance of a first CDN entity is above a first result, a second CDN entity for content distribution to a client device. The selection is performed subject to the constraints that a service performance of the second CDN entity is below a second threshold and resource consumption in regard of the second CDN entity is lower than a resource consumption in regard of the first CDN entity.
