Preface – This post is part of the Cloud Computing series.

Introduction

The network is a cloud service provider that provides a network to cloud platforms. Companies can access their network infrastructure directly for networking purposes. We can efficiently operate the network and achieve the outcomes.

For example, Amazon offers web hosting, private cloud, storage as a service, and other service providers provide bandwidth on demand and hosted network as a service. The provider working for a customer decreases the workload of the customer. It also allows us to deploy custom routing protocols.

To use network-as-a-service, we can purchase them through a subscription and pay-per-use model. We can start our development journey with a network at a meager cost.

New features of Network-as-a-Service

Network as a service (NaaS) is an emerging model for organizations to consume network infrastructure through flexible operating expense subscriptions, including hardware, software, management tools, licenses, and lifecycle services.

Custom routing content, monitoring, and filtering features have been recently added to NaaS. Moreover, it benefits those without previous investment in WAN (vast area network). NaaS is selected over other models because it eliminates capital and hardware investments.

Service Models of NaaS

There are three service models of Network-as-a-service

• Bandwidth on demand
  It is through network connectivity that users request bandwidth according to business needs. Here the capacity depends on the nodes and users. The prices can be modified to the traffic demands of the nodes connected to the website or server.

• Virtual Private Network
  A virtual private network (VPN) allows us to receive data between public and private networks. It provides an encrypted network and hides our IP address while sharing sensitive data between different organizations.

• Mobile Network Virtualisation
  These refer to abstracting network resources that deliver from hardware to software.

How does NaaS works?

The traditional organization used to consume enterprise network infrastructure. NaaS allows enterprises to consume and outsource the entire lifecycle of enterprise network deployment with the help of hardware, software, licenses, and services. All of these are delivered in flexible consumption or subscription-based offering models, and sometimes these can account for an additional expense for an organization.

Network-as-a-service also helps enterprises manage, update, troubleshoot, monitor, and end-of-life-support. For using the NaaS model, the end-user has to log in to the web portal where they can get online API. After that, we can customize the router and pay for the capacity used.

Benefits of NaaS

• Allow more rapid development of new features and functionality.
• Flexible connectivity for reliable remote access.
• Proven network designs and configurations developed in concurrence with customers and industry experts
•  NaaS partners proactively send you monthly reports, helping you detect issues and significant trends.
• Before installing the NaaS, the cloud platform provides documentation and an in-depth summary of the IT environment.
• NaaS offers better voice quality, more efficient call routing, and improved network management.
