Learning Center - What is NaaS (network-as-a-service)?

Network-as-a-service (NaaS) is a cloud service model in which customers rent networking services from a cloud vendor instead of setting up their own network infrastructure. Network-as-a-service (NaaS) is a cloud service model in which customers rent networking services from cloud providers. NaaS allows customers to operate their own networks without maintaining their own networking infrastructure. Like other cloud services, NaaS vendors run networking functions using software, essentially allowing companies to set up their own networks entirely without hardware. All they need is Internet connectivity.

NaaS can replace virtual private networks (VPNs), multiprotocol label switching (MPLS) connections, or other legacy network configurations. It can also replace on-premise networking hardware such as firewall appliances and load balancers. A newer model for routing traffic and applying security policies, NaaS has had a major impact on enterprise networking architecture. Learn more in the Cloudflare Learning Center.
