Introduction

Every application we use stores our data and shows our progress always. The online banking and transaction applications store our transaction details and display them. Did you ever wonder how the application shows details even from the past years? Where do they store the details? Yes, you guessed correctly. They store all the details in a “cloud”.  
Cloud Computing is a technology that uses remote servers to store, access, and manage data online. The data can be audio, video, files, images, text, etc. Cloud computing is highly reliable as we can access the data on the cloud from anywhere and any device. The cloud offers us services based on our requirements and our purpose. In this article, let’s learn about a service provided by cloud Naas - Network as a Service.

Naas - Network as a Service

Naas is a service offered by the cloud to allow the users to avail networking services from the cloud providers and operate their own networks without maintaining any infrastructure. Naas allows us to deploy custom routing protocols. It uses virtualized network infrastructure to provide services to the customer, and the service providers take up the responsibility of maintaining and managing the network resources. It offers the network as a utility to the customers on a pay-per-use basis. This service needs only an internet connection as it does not need any infrastructure or hardware to operate from the user’s side.

How does Naas work?

The user needs to log in to the web portal provided by the cloud to use the services. The user can then customize the routing protocols according to requirements from the online API. The users will be charged for the capacity and APIs they use. The capacity or protocols can be customized and changed anytime. The mobile Naas offers efficient and flexible control over mobile devices. It uses virtualization to simplify the architecture to create efficient processes.
