1.5.4 Evolving the Stack From VNFs to CNFs include CNV's (container native virtualization)

[SaadUSheikh]

The emergence of Kubernetes as the most widely used container orchestration layer allows telecommunications operators to shift their infrastructure over from more bespoke, expensive, and higher friction stacks to a de facto standard platform while also improving performance and resiliency. The extensibility of Kubernetes should allow a gradual transition from legacy VNFs built on OpenStack or VMWare over to a Kubernetes telco stack that accommodates all aspects of their business - including legacy VNFs, which can be easily managed via an abstraction layer on top of Kubernetes (KubeVirt/CNV/Virtlet/Openstack).
