Abstract
Concepts and technologies are disclosed herein for creating cross-service chains of virtual network functions in a wide area network. A controller can receive a chain request from a requestor. The chain request can specify functionality that is to be included in a service chain. The functionality can include a first function and a second function. The controller can compute a route associated with the service chain. The route can specify a first site that hosts a first service that provides the first function and a second site that hosts a second service that provides the second function. A first virtual network function can be located at the first site and a second virtual network function can be located at the second site. The controller can configure edge devices and forwarding devices to various entities at the two sites to enable the cross-service virtual network function chain.
