Making WAN ubiquitous: SD-WAN still has huge room for development

[[177476]]

The impact of globalization has become extremely far-reaching under the protection of technology. It is our common goal to achieve widespread popularization of the Internet in the growing corporate environment.

From the way we eat and dress to the way we learn and communicate, the impact of globalization is evident in every aspect of life. Since the Internet connects us all, the whole world has become a competitive environment for companies when it comes to technology.

Network topologies have been changing since the 1980s. We are now entering the era of Software Defined Wide Area Networks, or SD-WAN. Although this technology has not yet become mainstream, the adoption and deployment of this solution is increasing.

This software-defined technology for WAN connections can be used to connect corporate networks over long distances.

CIOs may lack awareness when deploying these technologies, but sometimes government agencies may also hinder the deployment of these technologies. Since most companies' existing MPLS contracts have not yet expired, CIOs will not actively deploy these technologies.

Given this, there will be some resistance among the CIO community and the transition period may be difficult.

However, even with all the challenges, the technology still has a lot of room for growth. According to IDC, the SD-WAN market will reach $6 billion by 2020. Just last year, the market size of the technology was only $225 million. In the next five years, the technology will maintain steady growth at a compound annual growth rate of more than 90%.

This prediction seems to focus heavily on SD-WAN, but the prediction is more focused on IoT. Due to the large amount of available data stored in connected devices, SD-WAN may also interfere with the function of IoT devices.

Take the interaction between IoT and SD-WAN of Augmedix, a US company, for example. The company can help doctors use wearable technologies such as Google Glass to communicate with patients in remote areas in real time and record patients' medical information. The delivery of this data is achieved through Aryaka's basic SD-WAN technology.

If everything is done over the network, the network will definitely become congested. A global SD-WAN built on a global private network is a viable way to avoid the congested public network.
