Network-as-a-Service (NaaS) is an innovative cloud service model that empowers enterprise IT professionals to select and configure network infrastructure components from a variety of options. The goal is to streamline deployment so that necessary equipment can be operational and managed within hours rather than weeks. This service model is delivered as a subscription, combining both hardware and software resources.
Despite its advantages, NaaS has faced slow adoption. Challenges such as confusion surrounding its definition, concerns about security, and lack of compelling business cases have hindered uptake. However, research indicates a significant shift: by 2030, over 90% of enterprises are expected to rely on NaaS for at least 25% of their network services.
The term "NaaS" lacks a singular definition. It might refer to simply acquiring networking hardware on a pay-as-you-go basis, to a managed service model, or to an advanced solution that tackles complexities in securing connectivity and scalability across multi-cloud environments. Essential to NaaS is a scalable, flexible architecture embracing automation and leveraging artificial intelligence for efficient management.
Different experts characterize NaaS in various ways. IDC analyst Brandon Butler describes it as a cloud-enabled, usage-based model for acquiring and orchestrating network capabilities that allows users to avoid owning or maintaining infrastructure. Neil Anderson from World Wide Technology notes that NaaS providers handle all equipment management, leaving organizations to pay for services rather than owning gear outright. Jay Gill from Pluribus Networks defines it as any virtualized networking option that abstracts underlying infrastructure.
NaaS delivery models vary, ranging from subscription hardware, where businesses pay a monthly fee but still manage installations, to comprehensive NaaS solutions, where providers own all equipment and offer a turnkey service.
The NaaS landscape features a variety of vendors, including traditional networking equipment manufacturers like Cisco and Dell, telecommunications firms such as Google and Verizon, and specialized multicloud networking providers like Aviatrix. Additionally, startups focusing on campus NaaS are emerging, contributing to market innovation.
The benefits of NaaS are significant: it offers IT flexibility and cost advantages by allowing organizations to treat networking expenses as operational costs. Furthermore, NaaS promotes faster deployments thanks to vendor expertise and provides access to the latest technological advancements, ensuring that enterprises remain up to date.
However, moving to NaaS does present challenges. Security concerns arise as organizations have to consider how to maintain control and conduct traffic inspections when outsourcing security measures. Additionally, integrating NaaS can be difficult for companies with existing investments in networking infrastructures. Any transition also risks fluctuating operational costs that may exceed initial budget estimates.
Recent industry developments suggest a growing interest in standardized frameworks that could facilitate NaaS adoption. The MEF, for example, has proposed a NaaS framework that aims to create a unified cloud experience across service providers.
Campus and local area network (LAN) NaaS has emerged as a particularly promising area, with rapid revenue growth expected in the coming years. As various vendors introduce zero trust security features into their NaaS offerings, the potential for enhanced enterprise network security is expanding.
In conclusion, while the journey towards widespread NaaS adoption is complex, its potential to transform how organizations manage their network infrastructures is significant, and ongoing developments indicate a bright future for this model.
