There’s a full-fledged war going on in the SD-WAN world, and it’s kinda fun. Just take a look at what’s happened in the past week. VMware today announced that VMware NSX SD-WAN by VeloCloud will be integrated with Microsoft Azure Virtual WAN. Riverbed also announced a link-up with Microsoft this week. And on Monday, CenturyLink expanded its SD-WAN portfolio. Meanwhile, Nuage Networks, the networking virtualization unit owned by Nokia, last week announced a launch of its SD-WAN 2.0 platform.
