SD-WAN Market Growth Opportunities by Regions, Type and Application; Trends Forecast

The global SD-WAN market is being driven by an increasing demand for cost-effective network management, network security and visibility, and simplified network architecture, and the popularity of cloud computing. In 2017, the market was valued at $676.9 million, and it is expected to demonstrate a CAGR of 54.1% during the forecast period (2018–2023). Software-defined wide-area network (SD-WAN) is used to connect enterprises, which have data centers and branch offices across long distances. 

WAN optimization solutions offer a variety of advantages, such as cloud-ready networking infrastructure, real-term business productivity, secure optimization, and greater virtual flexibility. Owing to these, WAN optimization solutions have become extremely popular among IT organizations. Seeing this, a software provider, named Citrix Systems, added new features including secure web, multiple deployment modes, prioritization of applications, and cloud connectivity to its upgraded NetScaler SD-WAN. Such enhancements in the products offered by key players are expected to boost the SD-WAN market further. 



A robust virtual network is the requirement of new technologies such as big data, internet of things (IoT), and machine to machine (M2M) communication. SD-WAN solutions provide nodes or remote offices to connect to the internet via high-speed broadband, at the same time safeguarding the quality of service (QoS) and compliance requirements, which multi-protocol label switching is unable to do on its own. Another trend being observed in the SD-WAN market is the demand for managed SD-WAN services to deal with the lack of IT resources and network security. 

The market is being driven by multiple factors, one of which is the need for cost-effective network management. As organizations are expanding geographically, their broadband connectivity demand for enterprise area network has increased. Traditional WAN models are becoming unsuitable, as their manual configuration is time-consuming and complex. SD-WAN solutions offer a way out of these problems by reducing the overall operational cost by making them centrally manageable and automating the configurations of WAN edge routers.


The global SD-WAN market is segmented by region, offering, industry, implementation type, and appliance. The implementation type segment is categorized into outsourced and in-house services. Out of these, the larger share was held by in-house SD-WAN services in 2017, a trend which is predicted to continue during the forecast period. However, the outsourced category is expected to attain a higher CAGR of 59.5%. The shift toward outsourced implementation would be because of its lower failure risk and less complexity, compared to in-house deployment. 

In 2017, the largest revenue share was accumulated by virtual appliances that are also expected to lead the SD-WAN market during the forecast period. This attributed to the wide-ranging application of physical and virtual appliances in small branch offices, data centers, large offices, and cloud platforms such as amazon web services. As the number of such settings increases, virtual devices would be used in ever-increasing numbers across the world. 

Therefore, it is clear that the market for SD-WAN is slated to advance during the forecast period owing to the advantages offered by SD-WAN over traditional WAN.
