What are the Benefits of SD-WAN Technology?

Enterprise Networking Mag | Thursday, December 09, 2021

SD-WAN is undergoing rapid and dramatic change as a result of the need for digital transformation, and unlike MPLS networks, which tie companies into a contract with a single provider, SD-WAN networks allow companies to accommodate several carrier options.

Fremont, CA: SD-WAN is getting a lot of attention these days, and for a good reason. With the rise of edge computing and digital transformation, the SD-WAN industry is expanding. According to Gartner, more than 90% of WAN edge infrastructure updates will be SD-WAN (or other virtualized platforms) rather than traditional routers by the end of 2023. However, there is a lot of misunderstanding about what SD-WAN is and why it is so crucial. SDN is a cloud-computing approach for a company's internal data centers. It was created to give network managers a centralized interface to respond swiftly to changing business requirements. SD-WAN connects the headquarters' data center and branch sites via the cloud and the internet.

Some of the benefits of SD-WAN Technology are:

Maximized uptime

Businesses can save time troubleshooting and boost uptime by using a centralized management interface. They can achieve seamless redundancy by combining numerous ISP and WAN connections in case one link fails. Failover to a backup connection is not always available in MPLS networks.

Better reliability

SD-WAN is designed for cloud connectivity as well as remote access to on-premises resources. It also makes cloud applications like SalesForce and Microsoft Office 365 more efficient and reliable.

Cost savings

Because SD-WAN eliminates the need for expensive routers and other traditional network equipment at each location, it is inherently less expensive than traditional hub-and-spoke networks. Companies also get rid of the necessity for local technicians to install and maintain the network. Furthermore, some businesses may be unable to afford the expensive cost of an MPLS circuit at small, remote locations, assuming that such a circuit is even available in rural areas. SD-WAN costs (hardware, software, and support) are predicted to be up to two and a half times lower than standard WAN designs.

End-to-End Visibility

Using a single administration interface improves network visibility, control, and analytics. Traditional networks lack the ability to provide insight on network and application behavior. SD-WAN provides IT managers with a comprehensive view of the whole enterprise network, from the branch to the cloud to the corporate headquarters.
