Methods, systems, and computer storage media for providing access to computing environments are provided. Based on a resource-ownership policy manager (i.e., a self-service engine and a runtime policy evaluation engine) that provides resource-ownership policy operations executed to apply a resource owner's policies only on resource owned by the resource owner. In operation, at runtime, a first resource instance is identified and an entity is determined to be the resource owner of the first policy and first resource instance. The first policy is applied to the first resource instance because the entity owns both the first policy and the first resource instance. A second resource instance is identified and the entity is determined not to be the resource owner of the second resource instance. A second resource policy of the entity is not applied to the second resource instance because the entity is not the owner of the second resource instance.
