[Request] VM vs Kubernetes with different CNI

[Hazmi35]

Based on this video: https://www.youtube.com/watch?v=Y4pOmi0j_90, EKS has noticeable network overhead which could be different on different CNI. Cillium for example uses eBPF and replaces kube-proxy which could have faster packet processing.

Not sure for EKS, but on GKE using Dataplane V2 or AKS using Azure CNI Powered by Cilium would use kube-proxy-free CNI implementation.

It would be interesting to see how different CNIs impact network overhead. While the difference might not be huge, Cilium's use of eBPF instead of iptables should provide a significant performance boost.

If you ever have the time to benchmark it, that would be awesome. Looking forward to your content as always.
