Cloud Computing Network as a Service(NaaS)
Networks as a Service allows us to access to network infrastructure directly and securely. NaaS makes it possible to deploy custom routing protocols.
NaaS uses virtualized network infrastructure to provide network services to the consumer. It is the responsibility of NaaS provider to maintain and manage the network resources which decreases the workload from the consumer. Moreover, NaaS offers network as a utility.
NaaS is also based on pay-per-use model.
How NaaS is delivered?
To use NaaS model, the consumer is required to logon to the web portal, where he can get online API. Here, the consumer can customize the route.
In turn, consumer has to pay for the capacity used. It is also possible to turn off the capacity at any time.
Mobile NaaS offers more efficient and flexible control over mobile devices. It uses virtualization to simplify the architecture to create more efficient processes.
Following diagram shows the Mobile NaaS service elements:
NaaS offers a number of benefits, some of them are discussed below:
Each consumer is independent and can segregate the network.
Customers have to pay for high-capacity network only when needed.
There exists reliability treatments that can be applied for critical applications.
There exists data protection solution for highly sensitive applications.
Ease of Adding new Service Elements
It is very easy to integrate new service elements to the network.
There exists more open support models, which help to reduce the operation cost.
Isolation of customer traffic
The customer traffic is logically isolated.
