A Software-defined Wide Area Network (SD-WAN) is a cloud based WAN infrastructure that can be used to leverage MPLS, LTE and broadband internet services – to securely connect users to applications. SD-WAN is a centralized and scalable solution that is easier to use, easier to scale and less costly than traditional models. 

An SD-WAN uses a centralized control function to securely and intelligently direct traffic across the WAN. This increases application performance, resulting in enhanced user experience, increased business productivity and reduced costs for IT. SD-WAN is designed to fully support entire applications hosted in on-premise data centers, public or private clouds and SaaS solutions such as Salesfore.com, Workday, Office365 and Dropbox, while delivering the highest levels of application performance.
