Let's start by defining what NaaS is and what it isn't.
Gartner defines NaaS as: "A delivery model for network functionality as a service, which includes the following capabilities:
- Self-service capability
- On-demand usage
- Ability to scale up and down
- Billed on an OPEX model
- Consumption-based, via a metered metric such as ports, bandwidth or users (not based on network devices/appliances)
- NaaS offerings may include elements such as network switches, routers, gateways and firewalls."
Gartner predicted that adoption of NaaS would increase from less than 1 percent of organizations in 2021 to 15 percent by 2024.
NaaS models can be applied in several areas of the enterprise connectivity architecture — essentially anywhere there's a network service. This includes the data center, cloud networking, wide area networks (WAN), and campus and branch office networks.
This report focuses on NaaS solutions across each of these areas.
