Why HN links it
Commenters link to Unikraft's KraftCloud pricing page and mention its closed beta for a Linux built for VMs. The comments are bare links or brief notes and do not judge the writing.

What Hacker News says?
Fully agree, doing reactive autoscaling when the actual boot time is slow is an inherently hard problem. We've done years of research into building specialized VMs (unikernels) and fast controllers to be able to provide infra that allows VMs/containers to cold start, and thus autoscale/scale to zero in milliseconds (eg, a simple Node app cold starts in ~50 ms). If interested, you can try it out at kraft.cloud, or ch…

HN discussion[Disclaimer: I'm with KraftCloud] For what it's worth, Firecracker/the VMM is only one part of the boot process. Among others, there's also the controller and the VM/OS itself that typically slow things down. In other words, it's not enough to just switch in Firecracker and expect cold starts to immediately drop to sub-second levels. On kraft.cloud we've fundamentally redesigned the cloud stack to be able to cold st…

HN discussionI think it can benefit both parties -- underprovisioning for a smaller bill and then increasing when demands need it so as to prevent degregation in QoS. That said, if load increases exponentially high it can induce high costs. Some cloud providers do not offer memory (or just any resource) ballooning, like AWS, so there you will experience the problem you have discussed about over-provisioning. However, we aim to a…

HN discussionIt's possible to run Unikraft unikernels via kubernetes with minimal interference to the ecosystem, check out the talk at CNCF: https://www.youtube.com/watch?v=cV-xawN9_cg We'll be launching managed kubernetes support for Unikraft unikernels soon too at https://unikraft.io

HN discussionOne way to reduce compute costs significantly is by using a much lighter stack . Typical deployments to the cloud are based on the traditional OS model, and more often than not are a container-in-a-VM solution to deploy some service. The reality here is that there is so much unused, unnecessary and wasted compute resources. Why deploy a full OS and kernel which will only ever serve static web content, for example. A…

on “My VM is lighter (and safer) than your container (2017)”Containers are perfect for build environments and for creating the root filesystem. The issue is that the kernel these days are super bulky and are intended for multi-user, multi-process environments. Running a container runtime on top just makes it worse when you're looking for "isolation". This paper argues that when you build a extremely minimal kernel (i.e. ditch Linux entirely) and link your application against…

on “KraftCloud”Hi, author here, You can, and we've written about the differences also, here [0]. The summary is that there is still a performance hit for boot time (100s of milliseconds to seconds vs. 1 to 100 of milliseconds for Unikraft); performance hit at runtime (even removing the syscall boundaries has a less-than-ideal impact based on previous studies); and, there's extra bloat from the image size itself (the image is still…
