Generating a core instance via a first access network device of a first access network, wherein the core instance facilitates operation of a second access network via a second access network device of the second access network is disclosed. Generally, implementing a core network can be highly resource intensive, e.g., high labor, equipment, and monetary costs. The level of resources that are conventionally committed in developing a core instance can be a significant barrier for many small or medium sized entities. The disclosed subject matter discloses a configuration component that can generate a core instance that can be performed at a remotely located access network. In an embodiment, a remotely implemented core instance can be updatable. Further, in response to a remotely implemented core instance failing to perform, a monitoring component can facilitate a failover operation.
