Who’s going to re:invent in Las Vegas next week? DM me if you'd like to hang out, talk about high performance cloud infrastructure, live migration, eBPF, Spot Instances - or all of the above! Can’t wait to see everyone! #aws #reinvent #reinvent2025

Nice that one can use network-bypass techniques without crazy vendor frameworks or kernel mods. Even cooler that one can recreate iptables functionality like this for faster inter-host networking

People aren’t ready for the next blog post from @loopholelabs.io If you thought the XDP post was interesting (linked below) this next one is going to blow your mind. Here’s a hint: What do chess engines and NAT’s have in common?

Great post by @alex.sorlie.io

An eBPF Loophole: Using XDP for Egress Traffic XDP is Linux's fastest packet processor but only handles incoming traffic. We found a loophole in how the kernel determines packet direction to make it work for outgoing traffic too! Blog post with details 👇 loopholelabs.io/blog/xdp-for...

Using XDP for Egress Traffic

XDP only works for ingress. We found a loophole that lets it work for egress. Here's how we did the impossible.

Who is coming to KubeCon NA 2025 in Atlanta?

What if we could pick up a k8s cluster and move it w/out service disruption? We demo’d this at Kubecon NA 2024 by moving a @kubernetes.io cluster running Valkey from AWS to Azure and then GCP all without disruption! this is pure magic from @felicitas.pojtinger.com . loopholelabs.io/blog/zero-do...

Reliable Cross-Cloud Kubernetes on Spot Instances with Architect

Live migrate entire Kubernetes clusters — stateful workloads included — between AWS, Azure, GCP and bare metal with zero downtime. With Architect and PVM you can cut cloud costs by up to 90% and end v...

New blog post! Run any application on Spot Instances with zero downtime and 75%+ cost savings - and no code changes required. Architect eliminates the reliability concerns that previously made Spot Instances impractical for production workloads. ⬇️ Link in comments ⬇️
