Network as a Service (NaaS) is an innovative cloud model that enables users to manage their networks without the responsibility of owning, constructing, or upkeeping their infrastructure. NaaS is a cloud-delivered solution where organizations subscribe to network capabilities from a NaaS vendor instead of building them in-house. It encompasses various services, including hardware rentals, connectivity, maintenance, consulting, analytics, and more.
NaaS replaces the need for capital expenses (CapEx) associated with physical networks. Instead, it provides adaptable operating expense (OpEx) subscriptions that encompass hardware, software, management tools, licenses, and lifecycle services.
Users can scale up or down based on demand, rapidly deploying services as needed.
NaaS has the capability to substitute hardware-based elements such as VPNs, load balancers, firewall appliances, and MPLS connections.
Organizations gain agility by paying for services based on usage and tracking billing efficiently.
AI-driven insights help improve utilization, optimize workload traffic, and enhance security.
Traditional network models require planning, deployment, and expertise. NaaS simplifies this process.
Vigilant monitoring for updates and security patches is crucial given technological advancements and the presence of security threats.
Historical issues with service provisioning and resolution are streamlined with NaaS.
NaaS models shift the focus from architectures to outcomes. With the growing complexity of multicloud environments, NaaS helps track service-level objectives (SLOs), predict future needs, and achieve unique business goals. NaaS services include managed SD-WAN, network access (including wireless), security, unified communications, and more. These services can be deployed in public clouds or on virtualized customer premise equipment (vCPE).
