What is SD-WAN?
Software-defined WAN (SD-WAN) is a virtual WAN architecture that allows users to securely connect to applications by freely combining forwarding services, including Internet services such as MPLS, LTE, and broadband.
SD-WAN uses centralized management capabilities to guide traffic over the WAN safely and intelligently. This improves application performance, improves the user experience, increases business productivity, and reduces IT department costs.
A typical WAN consists of traditional routers and is not for the cloud. This type of WAN requires backhauling all traffic, including traffic to the cloud, from branch offices to hubs or headquarters data centers to which advanced security inspection services can be applied. The delays caused by backhauls reduce application performance, resulting in a poor user experience and reduced productivity. The SD-WAN model, unlike traditional router-centric WAN architectures, offers the highest levels of application performance while providing SaaS solutions for on-premises data centers, public and private clouds, Salesfore.com, Workday, Office365, Dropbox, and more. It is designed to fully support applications hosted on.
