Enterprise Wide Area Network (EWAN) Services Are Delivered Using The Network-As-A-Service (NaaS) Subscription-Based Business Model

 

Network-As-A-Service

Network-As-A-Service (NaaS) can be challenging to set up and manage routers, protocols, WAN optimizers, and other elements like firewalls and software-defined WAN endpoints. These responsibilities are handled by a third-party provider and then made accessible to enterprise clients through Network-As-A-Service.

Infrastructure functionality may be included in a single Network-As-A-Service flat fee, depending on the service provider, or the company may pay separately for each service, which may include SD-WAN, optimization, and firewall or other security. Some NaaS providers have areas of expertise, such as services for mobile and temporary locations, ultra-simple deployment, or ultra-secure connectivity. The majority of Network-As-A-Service buyers are small and medium businesses, especially those without a prior WAN investment.

The emergence of so many alternative service models over the preceding ten years has increased interest in the prospect among larger businesses. Since NaaS eliminates a sizable percentage of the capital investment cost for network equipment, it appeals to startup business owners. Network-As-A-Service reduces the time that network staff must spend maintaining the network as well as the degree of expertise and training that staff members must possess. With NaaS, the network basically turns into a service that you pay for, much like energy, water, or heat.

In the Network-As-A-Service business model, IT staff members administer the organization's network through a portal rather than a jumble of network management tools and piles of gear. A leased line to a neighbouring data centre or the internet can be used to link a new location to the WAN and the nearest point of presence (POP) of the NaaS provider.

Similar to IaaS and another subscription model, Platform as a Service, a Network-As-A-Service platform offers networking equipment as a service (PaaS). According to Butler, PaaS is primarily concerned with application development environments. IaaS stands for "any sort of infrastructure that is supplied as a service." Therefore, it might be networking, computer storage, or a combination of the two.

Network-As-A-Service and IaaS vary in that NaaS is provided by networking companies, whereas IaaS is offered by cloud companies. Network-As-A-Service can be included to an IaaS subscription or provided independently to companies who choose to host their own servers.
