With so many network boundaries being navigated (application, service, cloud providers, subnets, SD-WANs , etc.), network operators and engineers cast as wide a net as possible to source their telemetry. This connectivity layer can include tech like WiFi and Bluetooth or network abstractions like WANs and SD-WANs, among others.

The Dutch engineering company had built a global wide area network (WAN) out of MPLS and Internet services connecting 17 locations 14 in Europe and 3 in the Asia Pacific with about 800 mobile and field employees. Cloud applications were starved for bandwidth as they were backhauled across a 10 Mbits/s connection to the datacenter.
