A managed SD-WAN is where a service provider adds on value to the network with its own additional features. A benefit of using a provider's SD-WAN as a service is an organization can focus on business goals rather than managing an SD-WAN.

A Software-defined Wide Area Network (SD-WAN) is a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including MPLS, LTE and broadband internet services – to securely connect users to applications.

SD-WAN solutions must extend perimeter technology to each location—including security,  performance visibility, and ongoing monitoring. Further, this data must be exposed to the business without requiring additional servers, storage, or management infrastructure.

The goal of an SD-WAN configuration is to control which links your traffic takes by specifying the VPN tunnels or direct internet access (DIA) that certain applications or services take from a branch to a hub or from a branch to the internet.

Yes! SD-WAN provides similar performance and reliability to a dedicated MPLS circuit.

SD-WAN provides simplified QoS and prioritization of critical applications across the WAN. Rather than waiting for an up/down event, SD-WAN provides real-time traffic monitoring to divert business-critical traffic around brownout events. ... These bandwidth requirements can be a challenge for traditional WAN.
