CycleOS, an atomic and immutable Linux operating system.

CycleOS is the operating system behind every server on Cycle. It’s never installed to disk. Each time a server boots, it pulls the latest CycleOS from the platform over the network and runs it from there.

In this video, the Cycle team walks through how CycleOS is built and delivered, and why that matters. You get the same OS and kernel on AWS, GCP and bare metal. Every reboot is a clean slate at the OS level, and picking up a security patch only takes a restart.
