The Importance of WAN Optimization in SD-WAN

SD-WAN greatly reduces the complexity of deploying and maintaining WANs. It does not, however, remove some of the key issues that users face when working with software over wide-area networks. Modern web applications, while often efficient, still require large amounts of data to be moved over the WAN. The dependence on expensive MPLS networks that SD-WAN removes, increases the chance of organisations relying on less stable broadband links. WAN optimization provides the same benefits to SD-WAN users as traditional WAN users.
