After SaaS, IaaS and PaaS, along comes NaaS, a new term in response to the trend toward services on demand. Network as a Service offers a global network infrastructure solution and associated services on a subscription basis.
“NaaS addresses the desire for a network infrastructure that is rapidly deployable and scalable.
It means companies no longer have to invest in rapidly depreciating network equipment or manage the maintenance and upgrades. This is outsourced to a managed service provider, who designs and installs the network architecture. Providing round-the-clock support.
The integrator: a key role
For Daniel Thomas, Head of Solution Development at Axians UK, it is ideal for companies employing more than 500 people across multiple sites. Although this affects all business sectors, banking and insurance, government and local authority and healthcare lend themselves ideally to the concept. He says, “NaaS is not a technology, but a framework. It’s a solution rather than a product. Within this approach, the role of an integrator like Axians is especially important. In a “best-of-breed” approach, the integrator will select the best providers and the best technologies, brick by brick.
Cloud and network virtualisation
With these advantages, Network as a Service is set for strong growth in the next few years. The market research firm Global Market Insights is forecasting an annual increase of 35% in the world market for the period 2019 to 2025. During this period, it is expected to grow from USD 5 billion to 50 billion.

The growth in the Network as a Service market can be attributed to the rapid take-up of cloud technology as companies increasingly migrate their workloads to it. The increase in data generated by various digital platforms and the growing trend toward workforce mobility have placed enormous pressure on company networks. As a result, they are migrating to the Cloud, which will enable them to host a wide range of business applications.
