The techniques presented herein maintain network function (NF) resource adjacencies regardless of the shared or dedicated nature of the NF and independent of the segmentation of the NF's cluster resources across geographic management domains. To achieve this, the techniques use intent-based networking models in order to create NF resources that facilitate the network slice creation and resource allocation. More specifically, the techniques utilize a Yet Another Next Generation (YANG) model representation of a network slice to facilitate creation and state management of all NFs associated with a network slice instance. The YANG model enables inter-site and intercluster adjacencies where cloud-native container network interface (CNI) communications is invalid. This also provides reference points for inter-domain orchestration between the mobility NFs, the underlying data center switching resources, and wide area network (WAN) transport slices.
