PodChats for FutureCIO: NaaS – what, why, when and how

Andrew Lerner, VP analyst for Gartner noted the ton of hype lately over “NaaS” (Network as a Service). Enterprises generally like the notion of a flexible, consumption-based networking model regardless of user or application location (very cloud-like). He cautioned that not everything labelled NaaS is the real thing. “We’ve seen things marketed as NaaS that range from (basically) hardware leasing all the way to a true aaS offering,” he added.To discuss in greater detail how it applies to businesses in Asia is Jon Green, Chief Security Officer for Aruba, a Hewlett Packard Enterprise company.1.       What is Network-as-a-service (NaaS)?
