In cloud computing Network as a Service (NaaS) is provide remote network infrastructure as service securely with less cost. NaaS makes it possible to deploy custom routing protocols.

NaaS provide virtual network Infrastructure to provide network service to the business consumers. NaaS manage the network and security related responsibilities and also manage resources uses by consumers and decreases the workload. NaaS is also based on pay per use model.

Benefits of Network as-a-Service:
1. Near you and your end users.
More than 95% of the world’s enterprise business users are within 20 milliseconds from any of our POPS. Multi-segment TCP optimization technology minimizes the application performance impact of packet loss on both the first and last mile.

2. Service, not boxes.
You subscribe for the bandwidth you need, when you need it, instead of building your WAN for future growth. We offer global on-demand capacity, so you can quickly add bandwidth at any location.

3. Connect in minutes.
You can be up and running in minutes, not the days, weeks or even months it can take to deploy MPLS. You simply connect into the network using an IPSec-capable edge device over your business-class Internet connection (or a direct L2 connection) to one or more of our nearest POPs.

4.QoS.
Our network honors your Quality of Service (QoS) markings to prioritize business-critical applications by class (such as for real-time applications) over other data traveling across the network, guaranteeing performance levels. The ability to burst above your subscription provides even more capacity for peak loads without additional cost.

5. Security.
We can connect an IPSec VPN directly into the network at the closest POP for those cloud services that require secure private access. For us, this is as simple as setting up any other location on the private network.

6. Visibility.
Our web-based portal delivers end-to-end network-wide visibility. With our service-based offering, we do all of the management for you, providing 24/7 support via Network Operations Centers (NOCs) located on opposite sides of the world.

Some service models are
1. Virtual Private Network (VPN): Extends a private network and the resources contained in the network across networks like the public Internet.

2. Bandwidth on demand (BoD): Technique by which network capacity is assigned based on requirements between different nodes or users.

3. Mobile network virtualization: Model in which a telecommunications manufacturer or independent network operator builds and operates a network (wireless, or transport connectivity) and sells its communication access capabilities to third parties (commonly mobile phone operators) charging by capacity utilization.
