This is highly interesting considering AWS invented the MicroVMs for lambda, yet node on lambda is dog slow (both in latency and throughput). I can traumadump on request. I bet they could use some of this tech especially since their use cases are often not too dissimilar (auth validation, rule checking etc)

View on HN

seriously - if netlify can do 15ms warm start + 10ms cold start, wtf is lambda doing for the other 1500ms?

> they could use some of this tech

Firecracker is AWS tech, and was behind both Lambda & Fargate. I imagine it's all the enterprisey extras built on top that cause those issues.

It is originally AWS, though we forked Firecracker ~4 years ago now and maintain an internal version with custom hypercalls (command-and-control from within the VM, POSIX-style fork, etc.) and a number of other features. We regularly pull patches and fixes from upstream Firecracker. You can read about the differences here:

Weird time to advertise your product.

When would you prefer they advertise? Seems entirely relevant.

When they're contributing to the conversation. It's not relevant.

How is it not relevant? In what way doesn't it contribute?

It's on you to prove it does. In what ways does it contribute?

We now know about their unikraft VM, whereas previous we did not.

If only there was an HN guideline about not using the site primarily for promotion.

You said they didn't contribute and weren't relevant. Whether their account primarily exists for promotion is a separate question.

It's relevant because it's about TFA! I'm assuming you didn't read it: Netlify uses Unikraft MicroVMs

Netlify use Unikraft for microVMs; just explaining the variant of Firecracker they are using.

ICYMI:

> Over the past several months, our team has rebuilt the infrastructure behind Edge Functions, working closely with the team at Unikraft, who wrote about the experience from their side.

fargate is not firecracker

can confirm that this is true for the fargate product used by consumers.

as someone who worked on it

From the Firecracker README:

https://github.com/firecracker-microvm/firecracker

"Firecracker was developed at Amazon Web Services to accelerate the speed and efficiency of services like AWS Lambda and AWS Fargate."
