The folks over at Cilium took a look at a recent CNI benchmark comparison and unpacked it a bit. The recent announcement of their GraphQL-based Network Query Engine (NQE)—more information is available in this blog post —is also pretty interesting to me. Operating Systems/Applications.

This is an older post (more than 2 years old), but as far as I can tell the concepts are still quite applicable. Tirumarai Selvan has a comparison. Operating Systems/Applications. Eben Freeman shows how to integrate Istio, Envoy, and Honeycomb for detailed application statistics. Still, the idea is pretty cool.

In a subsequent academic paper, Miller demonstrated that 25-33% of the Unix applications tested with fuzz either crashed or hung when reading random Input. Worms, by comparison, are able to replicate on their own so the Morris worm exploited an overflow vulnerability in Finger to spread from system to system. What’s a worm?
