Network Functions Virtualization (NFV) transforms routers, load balancers, firewalls and other network devices into virtual instances that can be service-chained, spun up and down as needed, and are cloud-friendly. But if you're a hardware hugger or have been been burned by virtualization in the past, should you avoid NFV? Today's Heavy Networking guests want to change your mind. The Packet Pushers speak with Michael Pfeiffer, a Cloud Networking Architect for a VAR; and Brad Gregory, Senior Product Manager at Equinix.
