Why NaaS is set to change networking

In a world where everything from data storage to software delivery has embraced the cloud, networking remains one of the last functions still clinging to legacy models. Many networks continue to rely on hardware that is not only complex but also costly and difficult to scale. But the landscape is shifting. Network-as-a-Service (NaaS) has emerged as a new, service-driven model that promises to streamline network management, reduce complexity, and redefine how networks are built, maintained, and scaled. But what exactly is NaaS?

Understanding NaaS

Network-as-a-Service is a cloud-based model that delivers network capabilities on a subscription basis. Instead of investing in costly hardware and infrastructure or managing in-house, companies can use NaaS providers to access and configure their network resources through a flexible, scalable, and user-friendly platform.

NaaS has a key advantage. It allows companies to move away from a CapEx-heavy investment in infrastructure, towards an OpEx model that allows them to only pay for what they need, when they need it. This is especially useful for companies adopting hybrid or cloud-only strategies, as NaaS supports integrations between cloud and on-premise resources. While the model is still evolving, it’s clear that NaaS is more than just another cloud solution. It represents a big shift in how networks can be designed and delivered, with efficiency and usability put front of mind.

Why is Network-as-a-Service gaining traction?

The rising popularity of NaaS is partly a response to the current skills gap in networking. Network specialists are becoming harder to find, and with the increasing complexity of today’s digital environments, fewer organisations can afford the level of in-house expertise traditionally needed for robust network management. NaaS addresses this shortage by offering simplified, and easy to use interfaces that allow technical teams such as DevOps to configure and manage networks without needing extensive networking knowledge.

This emergence of NaaS also reflects broader expectations around cloud service models or as-a-service" models. Just as with SaaS and IaaS, organisations now expect more from their networks than basic connectivity tools and perimeter defences; they seek visibility, automation, security, and agility – all seamlessly integrated. NaaS addresses this demand, providing a more user-friendly experience without compromising on network robustness.

Making networking easier

While traditional network management is often resource heavy, time consuming and costly, NaaS, in contrast, allows companies to adjust their network capacity and services based on their current needs. Making it ideal for organisations with evolving digital demands, varying workloads or those navigating the transition to hybrid working models. By operating on an OpEx basis, NaaS eliminates the need for long term commitments and allows businesses to pay for the services they actually use. This offers a level of flexibility that empowers organisations to adjust their network spend in line with operational changes and better allocate resources as needed. 

For businesses looking to streamline operations, manage costs, and improve network efficiency, NaaS offers a solution that enhances both security and reliability. Many leading providers include built-in monitoring, threat detection, and automated maintenance services as part of their offerings. This proactive approach helps minimise risk, reduce downtime, and enhance business continuity, enabling companies to focus on growth without running into unexpected network issues or costly hardware investments. 

Misconceptions around Network-as-a-Service 

Despite its advantages, there are some misconceptions around NaaS. Many assume that it offers the same level of convenience as shopping on Amazon and allows you to simply ‘spin up’ a new network in a few clicks. In reality, NaaS is much more nuanced. Effective NaaS solutions go beyond offering routers and switches, they provide visibility, reporting, and analytics that meet business needs. Companies evaluating NaaS need to consider these wider capabilities in order to truly understand the value of a well-designed solution.

Another misconception is that NaaS is a plug-and-play solution that anyone can manage. While NaaS does aim to simplify network management, it still requires a strategic approach – especially in the initial phases. Many organisations learned this the hard way with cloud transformations. Those that rushed the transition without proper planning faced unforeseen costs and operational challenges. NaaS is no different. To fully realise its potential, companies should adopt a phased approach, starting with low-priority workloads and gradually scaling up.

Moving towards a NaaS future

For organisations in the UK, NaaS presents an opportunity to reimagine networking in a way that’s more aligned with the demands of today. But as with any transformative technology, a thoughtful approach is key. Companies should begin by assessing their network needs and identifying potential challenges, before diving in.

Importantly, NaaS providers must also continue to refine their offerings to make networks as intuitive as possible. With the right NaaS solutions in place, network management could soon move from a highly specialised field to one accessible by a broader IT audience, enabling organisations to meet demands with more confidence and agility. 

Ultimately, NaaS offers more than just a technological advancement, it represents a strategic shift in network management. By addressing cost, complexity, and scalability challenges, NaaS holds the potential to redefine networking for UK businesses, empowering them to be more responsive and resilient in an ever-changing digital landscape. For those ready to explore this model, NaaS can bring new efficiency, provide insight, and build a solid digital foundation for their operations.
