SD-WAN architecture is the high-level structure of the software and hardware system that make up the SD-WAN and how it’s deployed. The method of deployment or architecture is often determined by business scale, needs, and associated cost.
In the SD-WAN architecture, the high-level structure of the software and hardware system that makes up the SD-Wan and how it’s deployed, the primary benefit or advantage is added security and organizations utilizing SD-WAN benefit from end-to-end encryption across the entire network. All devices and endpoints are completely authenticated, thanks to a scalable key-exchange functionality and software-defined security. All communication between a central data center and branch offices, as well as communication to and from the cloud, is secure.
SD-WAN is typically offered in three different architectures; premise-based, MPLS-based, and internet-based. Each architecture type will vary in cost and benefits and while some may be more appropriate for a specific type of business each architecture offers the same solution and capabilities.
