SD-WAN is an overlay on top of broadband internet connections that allows enterprises to connect branch sites, datacenters, and cloud applications. It uses techniques like application acceleration, circuit bonding, load balancing, and QoS to improve application performance over the WAN. SD-WAN functions can replace routers, firewalls, and other edge devices with a "white box" that is inserted at the edge. This provides cost savings through faster provisioning and outsourced management compared to traditional MPLS networks.

 almost HaaS

13. APP ACCELERATION
SD-WAN can provide for a means to speed up
applications through a direct link to the computing
platform (like AWS or even Microsoft Office365) or
WAN optimization techniques.

14. LOAD BALANCING
Load balancing and link bonding can help ease
congestion by monitoring two broadband circuits
(cable modem, DSL, 4G/LTE or even fixed wireless)
for the best route. These functions allow for rapid
deployment of circuits, instead of waiting on
specialized MPLS links to be installed.

15. SD-WAN
 Cost control
 Lowers overhead for WAN setup, mgmt and
maintenance
Can be outsourced / managed by vendor
− save staff
Faster Provisioning
BC/DR
Greater WAN visibility
Higher need for security (more DIA)
