I would argue that the longtail of applications does not really care about the impact of overlay networks. For us, the biggest impact on low-latency application

  Overlay networks compound unstable networks. If your internal network latency spikes to 2ms from 0.5ms, normally that's not a huge issue but if you have micro-services that need to talk to each other- using my example, a 1.5ms round trip time would cause an additional 8ms of latency. Sure, that's a low number but if you already have 150ms of processing, adding another 10ms might cause issues. Also, if you're disabling the resource controls on kubernetes- you're kinda defeating the whole point.
