As enterprises grow, their Wide Area Network (WAN) becomes increasingly complex – geographically distributed with diverse connectivity links. They are also consuming more bandwidth capacity as users collaborate across regions, use Cloud-based services, access large rich-media files, and leverage other bandwidth-intensive applications.
In-house IT teams are facing significant challenges when addressing these demands due to the complexity, cost and static infrastructure of their existing WAN. Many of them are turning to Software-Defined Wide Area Network (SD-WAN) for a simpler, centralised way to manage their enterprise network, replacing more expensive and difficult to manage services such as Multiprotocol Label Switching (MPLS).
However, SD-WAN is still a relatively new technology for many businesses today. Building a whole SD-WAN architecture across enterprise locations in multiple regions can be a daunting task.
