> Some cloud providers - like GCP and DigitalOcean - do support nested virtualization, and they work pretty well with Firecracker. Using VM migration to run stable workloads on spot instances sounds very interesting :)

not necessarily. you can build custom kernel with pvm[1] and do it on aws.

Yes I also came to know across pvm. I feel like doing it on top of aws instances can bring a really nice way of migrating from spot isntances and paying less bills.

What are your thoughts on the other hand in using criu with docker and then deploying it on aws spot instances, is it possible

I don't see why not really

but the last few years, spot has been reclaimed way too often and the price discount is not as good as it used to be (era 2016-2017) so I prefer to use saving plan now. although quite a big portion of our fleet still use spot.

hm that was an interesting take, I had seen this youtube video by codedamn [1] on how spot instances are really cheap and had always wondered why people weren't using this, well now I understand that the incentives have changed. Thanks for telling me, I didn't knew it or maybe the creator of that video had created it quite recently (10 months from now isn't that much of a time unless things have changed)

Have things changed quite a lot in 10 months or was it the author maybe overhyping the usecase I suppose.

I am really wondering but is there any software stack that can work with multi cloud approach the best way. I feel like typescript is really great for such purposes for the most part, I hope that this doesn't get counted as too off topic. I am not a dev ops guy but I just like being frugal and checking different options etc. and I am just wondering what is the best "just works" cloud 2025 without being too much expensive like vercel or netlify.

Have a nice day!

Wow, I didn't know about PVM! So this should finally allow nesting of container/VM sandboxes?
