Software-Defined Wide Area Networks, SD-WAN, is set to have the same impact cloud had on the IT industry back when it first launched. But what exactly is SD-WAN?
In layman terms, SD-WAN is a WAN transformation that allows companies to use the Public Internet (in the form of cable, DSL, LTE, etc.) to augment or replace their current WAN connections (often Multi-Protocol Label Switching (MPLS)). It opens the door for faster WAN provisioning and the ability to use multiple WAN paths at the same time.
Many of the networking concepts leveraged by SD-WAN are not new; however, how these concepts are being packaged, is changing the face of WAN networking. Today, Internet vendors offer various aggregation technologies and are happy to sell multiple links on a site. Simplified central management of WAN resources is a very typical end customer request. SD-WAN addresses these requirements in a new, innovative, applications-centric way delivering unique cost savings, improved ease of management and better application visibility and control.
Here are some characteristics that define SD-WAN:
So why use SD-WAN?:
Gartner estimates that SD-WAN has less than 1% market share today, but it predicts that up to 30% of users will be managing their WAN through software by 2019.
