So, “Are we there yet” as a community & mature technology?
• No! Porting proprietary solutions onto a hypervisor does not solve the old problems
– Moving from closed HW solutions to a hypervisor on COTS HW is only a small step toward NFV
– Need for a “Cloud-Native” approach to VNF design from ground up
• Introducing a new service and provisioning resources remain too cumbersome
– Instead of connecting & configuring hardware boxes, we now configure VMs
– A bit faster with reduced professional services, but still a time consuming, tedious process
• Auto-scaling infrastructure is only partially here and in a limited way
– A programmable approach to auto-scaling? (see later example)
– SON-like capabilities in software network controllers?

VMware poised to lead the IoT/5G “4th Industrial Revolution”: Hierarchical Dynamic Service Networks
• SDN is at its infancy – Network Virtualization vs Server Virtualization
– Server (network node) virtualization is a requirement
– Innovating in the next-generation virtualized networks: Dynamic Service Networks
• NFV – first manifestation of true wide-are Network Virtualization
– VMware Network Virtualization: Network slicing and DSNs
– VMware NFVi provides the end-to-end, differentiated v-infrastructure for 5G readiness
– Cloudets for Mobile Edge Computing
• Hierarchical Network Slicing and the concept of Dynamic Service Networks (DSN)
– Network slicing is one of the most challenging problems – but a necessity for IoT
– Investing in carrier-centric technologies and solutions for IoT verticals

Self-orchestrating, Self-configuring VNFs
• A (logically) central VNF Registry maintains a registry entry for each enabled VNF
– VNF manifest, NFVi manifest, APIs supported, interoperability configuration attributes etc
• Extensions (annotations?) can enable auto-generation of VNF and NFVi manifests
• Marketplace of APIs and format converters can generalize the applicability of model
• A binding process generates the micro-orchestration actions needed to enable the new VNF
• Micro-orchestrator implements configuration set up and brings up the new (VNF) service
