SD-WAN is a software-defined approach to managing the WAN. Multiple vendors are providing different flavors of SD-WAN solutions but key features remain the same.
SD-WAN benefits include a single, centralized, cloud-delivered management dashboard for configuration and management of WAN, cloud, and security, template-based, zero-touch provisioning for all locations: branch, campus, and cloud, dynamically routed application traffic with application-aware routing, for efficient delivery and improved user experience, secure traffic across broadband Internet and into the cloud, reducing costs with transport independence across MPLS, 4G/5G LTE, and other connection types, improving application performance and increasing agility, optimizing user experience and efficiency for software-as-a-service (SaaS) and public-cloud applications and simplifying operations with automation and cloud-based management
