How Unikraft
Cloud works
Built for a new era of cloud: instant, scalable, efficient.
Cloud infrastructure is too slow
for modern needs
Cloud traffic is unpredictable, spiky, and changes in milliseconds
Legacy platforms were built for minute scaling
Result? Wasted resources, slow response times, and high costs
A platform engineered
for millisecond precision
Millisecond cold starts
Millisecond Scale-to-zero and instant autoscaling
Up to 100K+ workloads on a single server
Strong hardware-level isolation
Exponentially superior unit of economics
Docker-based workflows - deploy anything
Step by step to millisecond
performance
Ultra-efficient cloud stack
-
Minimal VMs built for speed and security
-
Based on Linux Foundation's Unikraft project
-
Only includes what your app needs
-
Modified Firecracker VMM for ultra-fast starts
Reactive network layer
-
Custom-built proxy and controller
-
React to requests in real time
-
Scale thousands of instances in milliseconds
Lightning-fast app startup
-
Pre-initialize apps and snapshot their state
-
Scale to zero, then resume in milliseconds
-

What happens when
a request hits Unikraft Cloud?
-
Proxy receives the request and buffers it.
-
Controller checks if an instance is active.
-
If not, the unikernel boots instantly.
-
When ready, the proxy forwards the request.
