Network as a services ( NaaS)

In this tutorial you will learn about the Network as a services ( NaaS) and its application with practical example.

Network as a services ( NaaS)

Network as a services ( NaaS) is a cloud architecture that allows customers to simply manage networks and accomplish the results they need without owning, constructing, or maintaining their own infrastructure.

NaaS may be used to replace hardware-based VPNs, load balancers, firewall appliances, and MPLS connections. Users can scale up and down in response to changing demand, quickly launch services, and remove hardware expenditures.

This model has the following components:

  • Due to the quick changes in technology and security risks, diligent monitoring for updates and security patches is vital.
  • Provisioning a new service is a manual procedure that necessitates the deployment and configuration of equipment at numerous locations by a technician.
  • Historically, service provisioning and issue resolution were time-consuming operations.

As networks have become more complex—with more mobile users connecting from anywhere and the cloud expanding—IT teams have been forced to stay up.

What are the advantages of NaaS?

NaaS streamlines the management and consumption of hardware and software technologies. It allows for increased speed, agility, and scalability.

With the importance of NaaS, there is little question that it will continue to expand to provide greater size, depth, and breadth of services.

  • IT automation and simplicity

Businesses profit when their expenditures are aligned with real consumption. They don’t have to pay for unused capacity, and they may dynamically expand capacity as demand grows. IT personnel are frequently required to travel to numerous places in order to execute improvements.

  • Accessible from any location

Today’s workers may require network access from anywhere—home or office—on any device and without the use of VPNs.

  • improved security

As a result of NaaS, the network and network security are more tightly integrated. Some manufacturers may “assemble” network security.

  • Visibility and knowledge

NaaS delivers proactive network monitoring, security policy enforcement, sophisticated firewall and packet inspection capabilities, and modelling of application and underlying infrastructure performance over time. Customers may also be given the option of co-managing the NaaS.

  • Better application experience

In a multicloud world, connectivity that provides the same user experience as if the application were hosted in-house is crucial. NaaS delivers AI-powered features to assist guarantee capacity SLAs and SLOs are met or surpassed. NaaS enables the routing of application traffic to assist ensure an excellent user experience and the proactive resolution of issues that arise.

  • Flexibility

NaaS services are offered via a cloud paradigm, which provides greater flexibility and customisation than traditional infrastructure. Software, not hardware, is used to implement changes. Typically, this is delivered through a self-service paradigm.

  • Scalability

Traditional, hardware-based networks are intrinsically less scalable than NaaS networks. Instead of acquiring, deploying, configuring, and securing new gear, NaaS clients just purchase extra capacity. As a result, they can swiftly scale up or down as needs change.

What are the difficulties of NaaS?

Compatibility :- The infrastructure of the NaaS provider may not be compatible with legacy systems that are still in existence – outdated hardware, on-premises-based applications, and so on.

Legacy data centres:- Many organizations still operate critical applications and operations in on-premise data centers rather than the cloud. This makes the transition to a NaaS model significantly more difficult (although services such as Cloudflare Network Interconnect can help overcome this challenge).

Vendor lock-in:- When a company migrates to a cloud service, there is always the risk of becoming overly dependent on that particular service provider. If the service provider’s infrastructure fails or their rates rise, vendor lock-in might have serious consequences.

The Prospects for NaaS

It is obvious that the migration of business clients to cloud services is the key driver of NaaS. And, while the networking industry is still figuring out how to successfully network the cloud world, NaaS might play a significant role in the future.

Pluribus’ Gill stated that networking must be virtualized and automated in order to support cloud-speed operations. “What services and business models will triumph is the fundamental question. Private cloud NaaS may be the most essential, with most applications remaining in private cloud settings.”
