In an example embodiment, an additional interface customer resource definition (CRD), which operates in conjunction with the normal CRD, is utilized. The interface CRD may be called a service CRD. The service CRD provides an abstraction of the original CRD by abstracting away all technical details that no other services should depend upon. The service CRD provides a façade to the original CRD. Both are kept in sync by a component called an operator, which infers the specification of the original CRD on the basis of the specification of a given service CRD. Furthermore, status updates sent to the original CRD that are relevant to the dependent services are mirrored back to the corresponding service CRD. Correspondingly, status updates with technical details that are too specific for the dependent services are not mirrored back.
