Cloud Computing Concepts: NaaS

 

·         NaaS stand for Network as a Service, it is one of the service models offered by cloud computing.

·         Network as a service (NaaS) is a business model for delivering network service over internet the internet on a pay per use or subscription basis.

·         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

·         From the customer's point of view, the only thing required to create an information technology (IT) network is one computer, an Internet connection and access to the provider's NaaS portal.

·         This concept can be appealing to new business owners because it saves them from spending money on network hardware and the staff it takes to manage a network in-house. In essence, the network becomes a utility, paid for just like electricity or water or heat. Because the network is virtual, all its complexities are hidden from view.

·         NaaS isn't a new concept, but its deployment has been hindered by some of the same concerns that have affected other cloud computing services -- especially questions about the provider's ability to guarantee high availability (HA).

·         Other concerns include dealing with service level agreements (SLAs), compliance issues related to data sovereignty and the possibility of vendor lock-in.

·         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.

Isolation of customer traffic: The customer traffic is logically isolated.

Independence: Each consumer is independent and can segregate the network.

Bursting: Customers have to pay for high-capacity network only when needed.
