Note Firecracker does not work on AWS cloud instances, apart from bare metal instances.

;( It should work on some azure instances and gce instances when you enable nested virtualization.
Firecracker: Secure and fast microVMs for serverless computing

#102Earlier quoted context omitted.
It's closest to Cloud Run. We run your containers and scale across regions to minimize your users' latency. You can't quite use it as a drop in replacement for Heroku since we don't have a Postgres offering. You can use fly to replace the web dynos in a Heroku app for faster performance, though.
Thanks for clarifying! Does it scale down to zero? If I have a very small hobby app that may only have a few users a day would it make sense to throw it on to fly.io?
It would make sense! We give free credits specifically for side/hobby apps (in theory, you can run ~3 microscopic VMS pretty much full time with this): https://fly.io/docs/pricing/#free-for-side-projects
We don't scale to 0 because the cold start experience for most apps is brutal. In the future we may be able to suspend VMs and wake them up quickly, or even migrate them to regions with idle servers.

#103I'm happy to see AWS is giving back to the open source community.
if you had to guess.. what are your thoughts on why this was open sourced? everybody i listen to seems a little confused by the "why" of this specific action

#104Will microVMs replace containers in short time?
i'd also like to know this..

Oh FOSS . Got it.
Do people still try to claim that source available is open source? I go by the OSI definition.
That was weird, I'm not sure why that comment got flagged.
I'm not sure what you're asking.
I really was confused about what "OSS" meant w/o the "F" in front.

This runs Amazon lambda, so presumably well enough?
You don’t think 12 years from now we’ll be laughing about how lame Lambda is? Coding practices change like the seasons. Every year is a little different, maybe a little better than the last, some things feel brand new, but the general patterns hold.
I'm sure we'll laugh about most things we are currently using and gasp when we need to revisit them in legacy systems. :)
Re: Firecracker: Secure and fast microVMs for serverless computing
#107I believe it is still using virtio. Therefore, disk read/writes are not good enough compared to other virtualization tech such as qemu
hello guys,
I'm sorry that my first comment was not enough informative.Now, I'm refering to the paper that I read couple of days ago [0]. If you look at the figure 8-9, FC has some issues with IO.
