Frequently Asked Questions

Dive into the following questions to gain insights into the powerful features that Unikraft offers and how it can elevate your cloud development journey.

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.

What’s a unikernel?

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.

Aren’t virtual machines heavyweight?

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).

How much smaller are Unikraft images?

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).

Built around the open-source Unikraft SDK

Adopt the most comprehensive unikernel library Operating System and tooling available.
