NETWORK-AS-A-SERVICE (NaaS)

What is NaaS?

• Network-as-a-Service (NaaS) is a cloud-based networking model where businesses can rent networking services like routers, switches, firewalls, and bandwidth instead of owning and managing them.
• It allows users to subscribe to networking resources on-demand, just like cloud storage or computing services.

Key Features of NaaS:

• On-Demand Access: Networking infrastructure is provided when needed.
• Pay-as-You-Go: You only pay for what you use.
• Remote Management: Managed via the cloud—no need for physical infrastructure.

• Security: Includes managed firewalls, VPNs, and other security services.

Services Offered in NaaS:

• Wide Area Networking (WAN) optimization

Benefits of NaaS:

• Cost-Effective: No need for heavy investment in hardware.

• Faster Deployment: Quicker rollout of networking services and updates.
