The hybrid WAN is here and this SearchSDN guide by Kevin Tolly, Founder explains how to buy and build an SD-WAN architecture. Learn about key features and ‘nice to haves’ before you approach vendors and make an acquisition decision.

The marketplace is full of SD-WAN vendors, each pitching a different value proposition. But one feature is the same for all SD-WAN architectures: the use of commodity bandwidth and computing resources.

So the first requirement of an SD-WAN architecture is a solid foundation. In the category of “must-have” features, some that are essential include:

  • Commitment to your SD-WAN vendor
  • Centralized policy and configuration manager
  • Aggregation platform

SD-WAN certainly appears to be a compelling option, but it is a very big commitment. Changing course once underway may require that you return to your starting point, losing both time and money. So look closely. Better yet, build a lab and try out several before you commit to an SD-WAN product.
