Doyle Research Case Study: SD-WAN at a Fortune-500 Retailer

doyle-logoDoyle Research interviewed the Director of Networking and Telecom at a large US-based retailer. This retailer has approximately 3,500 stores (around the world) across multiple brands. Revenues exceed $10B per year, and it has over 100,000 employees. Each store has several dozen distinct applications, including Point of Sale (PoS), which must be linked back to one of its three data centers and to the Internet. Its current WAN environment is a mix of MPLS and VPLS private circuits from a variety of carriers. All stores have some (limited) Internet connectivity. Annual spend on WAN circuits exceeds $25 million per year. The retailer has a sizable team of IT specialists to support the WAN across its global network.

To bring the availability and cost efficiency of Internet WAN transport to its own WAN network, the retailer looked at different SD-WAN solutions.
