We added @slicervm support to the K8s Cluster Autoscaler to launch worker nodes in microVMs
Harden your operator locally or in CI:
✅ Scale massively across many machines
✅ Simulate spot instance termination/draining
✅ Run e2e tests in GitHub Actions with nested virt

Where do functions fit in with Claw and Claude? Stable, energy efficient, deterministic automation.
This month we shipped Adaptive Concurrency.
The system figures out optimal load on its own. Big deal for long running tasks and ETL workloads.

We've launched a new design for SlicerVM - a fun way to learn and experiment with Firecracker over the holidays. With any commodity hardware or bare-metal cloud like Hetzner.

Live demo of our new code review bot (opencode slicer) for GitHub - it's faster, and more flexible than the built-in option.
Would you be interested in testing it out?

Queue-Based Scaling is ideal for long-running jobs and background processing - we planned it out in Q4 2024 - and now it's here! 😀 openfaas.com/blog/queue-base…

1/3 I patched the Cluster Autoscaler to work with Slicer (manages Firecracker VMs) and K3s.
My functions node pool for @openfaas scales to zero and up whenever needed.

The Headroom Controller adds low-priority Pods as a buffer when using autoscaling nodes in Kubernetes
Don't wait 1-2 mins for a new node - pay a tiny bit more for an instant start for your Pods.

Does it take 1-2 minutes for new nodes to get added to your cluster? Add some headroom for an instant Pod start.

Build vs. buy - extensibility with customer functions - the dev longs to create their own Heroku, the manager wants to get to market as fast as possible.
Of course we're biased and will do whatever we can so you can ship the capability ASAP.

New example UI for the @openfaas Function Builder API:
✅ Accept JavaScript from customers
✅ Invoke it from your existing product instead of using external webhooks
✅ Code is sandboxed with K8s best practices
