Vendors of all stripes—network hardware vendors, telcos, hyperscalers, and a new generation of cloud-based upstarts—are jumping on the network-as-a-service (NaaS) bandwagon, so it can be confusing to sort out who is offering what.Even the definition of NaaS is somewhat fluid. Is NaaS simply procuring networking gear on a pay-as-you go, subscription basis rather than buying it? Is NaaS just a different way of describing a managed service?
Or is NaaS something fundamentally different that addresses a growing challenge for network execs: how to provide network connectivity, resiliency, security, and scalability in a multicloud world?
