• Customers should approach SD-WAN with an open mind when it comes to costs and understand that savings may come from knock-on benefits.
• Customers should conduct their own trials into whether the internet is appropriate for a given application.
Cost Savings vs. Quality
Much of the initial hype about SD-WAN focused on cost saving. However, those looking to buy an SD-WAN solution should keep an open mind to cost and be aware that if savings are realized they may not come from the cost of their WAN solution. Indeed, initial experience suggests that SD-WAN solutions sometimes increase the cost of an enterprise’s overall spend on WAN. The complexity of managing SD-WAN means that it is not an inherently cheap technology. WAN savings may come over time as more and more MPLS is phased out of WAN architectures, but initial experience suggests that abandoning MPLS from day one is a risky approach and often results in unsatisfactory network performance.
