What’s Unikraft?
Unikraft GmbH is the company behind the next-generation cloud compute platform based on millisecond semantics, Unikraft Cloud. This is based on the open-source, Linux Foundation Open-Source project Unikraft.
“I've seen things you people wouldn't believe... libsql server running with Unikraft Cloud and cold booting in 30 milliseconds."
“Imagine running thousands of pods on K8s with just your app code and required libraries, like Alpine images on steroids.”
“Unikraft has been working on some really cool tech for the next-gen of serverless and now Unikraft Cloud lets anyone use it easily!”
A new era of cloud
Automatically accelerate your cloud app as an extremely efficient, green, and highly secure image without infrastructure headaches such as warm- or over-provisioned instances.
“Looks like the unikernel folks were on to something. Compute platforms are trending towards orchestrating micro virtual machines purpose built for running a single application.”
“Unikraft team has been working on some really cool tech for the next-gen of serverless and now Unikraft Cloud lets anyone use it easily!”
“I am very impressed with Unikraft. These people are pioneering a next generation approach to cloud computing that is much faster, secure, and sustainable than anything else I’ve seen in the space. This will be bigger than the Docker revolution from the past decade.”
“I've seen things you people wouldn't believe... @libsqlhq server running with kraft.cloud and cold booting in 30 milliseconds 🤯💎🚀”
“Imagine running thousands of pods on K8s with just your app code and required libraries, like Alpine images on steroids.”
“You guys are doing cloud rocket science.”
“This is some seriously impressive tech. I deployed a Rust + Axum API that can cold-start instantly without requiring any wasm specific modifications like Cloudflare Workers.”
“Hail Unikernels!! The future of Cloud Computing is here with Unikraft 🙌”
“Unikraft and Unikraft Cloud are messing with my head. It's a step change in cloud performance.”
“My favorite unikernel framework.”
“It is a gorgeous way to build lightweight and secure VM images.”
“If you want both security and lightness... you can actually have it!”
“I was actually more impressed with unikernels with Unikraft than WASM. (And that is saying a lot if you know how I feel about unikernels).”
“This has revolutionised our infrastructure — offering efficiency and scalability at a great price-point. It'll be a game-changer for all devops workflows.”
“We took Go codebase we've been working with from an average of ~4s startup with Docker on GCP to ~30ms on Unikraft Cloud.”
“The Unikraft folks are doing some incredible engineering!”
“This is certainly the future of zero-cost amortized compute per user 💯”
We're on a mission to change virtualization forever.

At Unikraft, we recently completed our SOC2 Type 1 audit. What we thought would be a process of improving security turned into a much more valuable journey about company maturity.
We generally like to think of the cloud handling gazillion requests per second, but a significant part of it is over-provisioned and so idle. In this post we look into the what, how and why what we term “The Idle Cloud” exists, and how to fix it.
Cold starts, slow autoscale, subpar scale to zero, severe over-provisioning and exploding bills. Must the cloud really be this complex? Part 2 of a two-part series.

If you're running services using public cloud infrastructure, then you're already massively overspending. Unikraft is on a mission to reduce cloud compute bills and increase performance and security.

A unikernel is a specialized OS/kernel designed to provide a lightweight, single-purpose execution environment for applications, without any unnecessary components to minimize resource usage and attack surfaces. Learn more.
They need not be! Unikraft unikernels are extremely lightweight and are fully- fledged virtual machines, providing strong, hardware-level isolation. VMs are the workhorse of public cloud deployments, and with Unikraft they provide the lightweight characteristics of containers of process (e.g., millisecond cold boot times).
The answer depends on the application of course, but with Unikraft we can confident say that most of an image’s size is due to the application itself. For example, an NGINX Unikraft image is under 2MBs in size. Do Unikraft unikernels come with security benefits? Yes, especially stemming from the fact that they have a minimal Trusted Computing Base (TCB), and everything is off by default (services, ports, etc).
