The explosion of SD-WAN has caught the telecoms market by surprise. The technology has matured quickly.
As Enterprise customers demand more flexible, simple and cost-effective cloud-based solutions the popularity of SD-WAN continues to rise. There are some 40 different vendors in the appliance landscape; it goes without saying that market consolidation (and consolidation of product lines) is likely – making it important for enterprise buyers to do their homework.

In a recent Frost & Sullivan study 51% of Enterprises surveyed indicated that they would deploy SD-WAN in the next 12-24 months. 33% of respondents had either already deployed an Australian SD-WAN solution or had deployment underway4.
Clearly SD-WAN is here for the long haul; we can only expect the growing trend to accelerate over the next few years.
Here’s some trends we’re seeing that make SD-WAN such a hot topic right now.
