Why this market will grow 1200% by 2021!

Easier turn-up of new locations With MPLS, as with any transport technology of the past, turning up a new site or upgrading an existing one is complex and time consuming. Each edge device must be configured separately, and the simplest of changes can take weeks. With SD-WAN, setting up a new location can be provisioned automatically, greatly reducing both time and complexity.

Virtual Path Control

SD-WAN software can direct traffic in a more intelligent, logical manner, and is also, like MPLS, capable of addressing QoS. SD-WAN can detect a path’s degradation and re-route sensitive traffic based on its findings. Also, having backup circuits stand by unused (and costing dollars, of course) is a thing of the past with SD-WAN.

Migration to Cloud-based Services

With traditional WAN architectures, traffic gets backhauled to a corporate or 3rd party data center, which is costly and reduces response times. SD-WAN allows traffic to be sent directly to a cloud services provider, such as AWS or Azure.

Security

SD-WAN provides a centralized means of managing security and policies, and utilizes standards-based encryption regardless of transport type. And once a device is authenticated, assigned policies are downloaded and cloud access is granted―quick, easy. Compare that to traditional WANs, where security is handled by edge devices and firewalls. Far more complex and costly.

…and last, but not least

SD-WAN can greatly reduce bandwidth costs, which are often the greatest expense IT organizations incur, especially if they’re connecting multiple locations. MPLS circuits are pricey, and SD-WAN can utilize higher bandwidth, lower cost options, such as broadband or DSL.

Does SD-WAN mark the end of MPLS?

Given the stringent QoS demands of some enterprise organizations, and the fear that SD-WAN won’t be able to accommodate them, it’s unlikely that SD-WAN will totally replace MPLS. And some organizations are simply averse to change, and/or fear their current IT staff doesn’t have the necessary skillsets to successfully migrate to SD-WAN, then properly monitor and manage it moving forward.
