Supporting Growth and Demand With Flexible Network Services
Network-as-a-Service (NaaS) is characterized as a cloud-based service where customers lease networking services from a service provider instead of managing their own infrastructure. This provides enterprises the flexibility to access services on demand and to manage a network without the necessity of owning or maintaining network infrastructure.
NaaS is positioned to replace on-premise equipment such as Firewalls, static SD-WAN, and MPLS connections. By implementing software-based networking functions, NaaS suppliers empower enterprises to spin up on-demand networks without relying on hardware. Current NaaS offerings encompass services such as managed SD-WAN and network access. For instance, this could involve Direct Connect services to cloud providers, SD-WAN features, and security functions like Firewall, CASB, and DDoS.
In a NaaS deployment, the provider takes responsibility for owning, operating, installing, and maintaining all physical network equipment, with the customer paying a monthly fee for these networking services. Since the service provider is responsible for uptime, users will have agreed upon SLA’s and predictability that can be published to both internal and external partners
There are many performance and cost advantages to using agile, scalable NaaS, including:1. Accessibility – NaaS is a cloud-based service where customers rent equipment and networking services from providers.2. Flexibillty – NaaS offerings include software-based subscriptions where users are able to add different features like remote access, SD-WAN, and security.3. Scalability – Management and allocation of network resources can be remotely shifted to sites requiring greater consumption.4. Cost Effectiveness – Users can take advantage of a variety of networking and security features, eliminating the number of suppliers, hardware, and services consumed at the edge.
NaaS promises to provide a higher degree of flexibility from the way in which networks have been typically deployed. Specific services across both security and networking can be purchased and implemented in real-time, rapidly increasing deployment to the edge. With NaaS, traditional infrastructure pain points – such as cost, configuration, management, and maintenance – are transformed into predictable, reliable features of the service.
