SD-WAN Regional Hub
An SD-WAN Regional Hub is a network model bringing the best of the hub and spoke and the full mesh architecture to improve performance as well as security, with simplified provisioning alongside extended connectivity.
Regional Hub architecture in SD-WAN is the organization of branches into logical regions which connect back to a central hub within proximity specific to that region – like a system of distributed and organized hub and spoke sites. This is designed to improve performance as well as security with simplified provisioning alongside extended connectivity.
Security and network services exist at the Regional Hub for efficient backhauling over a short distance. This is achievable now with SD-WAN operating as an overlay where distributed businesses connect all sites to the web where automated policies are applied. The most notable benefit, in line with the cost savings associated with SD-WAN, is the ability to change architecture without a significant amount of manual overhead.
