SD-WAN has been around for a little while. What makes now so important? Why is it gaining so much traction now rather than five years ago?
It's a very curious confluence of trends that happened that got SD-WAN started a few years ago. One of the main trends was that there was an inflection point in the number of services that moved to the cloud. These are workloads moving to the cloud. Even five years ago, there was a lot of reluctance. People thought cloud wasn't good enough from a performance and security standpoint. Once the workloads started moving to the cloud and the Internet became good enough to run business on, those were the two aspects that drove the timing of what has happened with SD-WAN. We called it next-generation WAN, or cloud WAN. Once the workloads transitioned to the cloud, we had this hybrid connect issue that came up. You couldn't send all your traffic back to the data center. That didn't make sense. There were increases of traffic required because the applications were becoming a lot more media-enabled. The last piece that came in was IoT. IoT is still at a fairly early stage, but if you think of a typical branch office in a company, you could have five users in it, and you could have 500 sensors. You could run those on the same network. That drove the growth of SD-WAN starting a few years ago.
