Abstract: A method for adaptive and intelligent Network Functions Virtualization (NFV) workload placement includes monitoring operation of a network with resources including one or more Virtual Network Functions (VNFs) and microservices; responsive to a request for a service in the network, decomposing the service into interconnected functional atoms, with the functional atoms located in one or more network domains including one or more of different data centers in the network and a user device associated with the service, wherein the functional atoms are decompositions of the VNFs and the microservices into a smaller level of functionality than the VNFs and microservices, wherein the functional atoms are based on isolability, observability, and measurability; and instantiating the service in the network based on the determined placement of the functional atoms.

Abstract: For instance, in the case of a software implementation, the terms “component” or “functionality” may refer to program code that performs specified tasks when executed on a processing device or devices (e.g., processor(s) 720). The program code can be stored in one or more computer readable memory devices as described above. The illustrated separation of components and functionality into distinct units may reflect an actual physical grouping and allocation of such software and/or hardware, or can correspond to a conceptual allocation of different tasks performed by a single software program and/or hardware unit.
