c12n is a 100% open-source, fully automated cloud platform that puts you back in control of your own sovereign Infrastructure as a Service (IaaS).

c12n is more than just an alternative to VMware; it’s a reliable, secure, open-source cloud solution that caters to modern enterprise needs, a liberation from the overpriced commercial solutions. Whether you’re managing a highly secure air-gapped environment or scaling from 5 to 500 nodes in a converged or hyper-converged setup, c12n gives you the tools to do so with ease. Our platform is entirely open source, meaning there are no licensing fees and no hidden costs – just open industry standards and transparent project development.

The power behind c12n lies in its foundation of proven open-source technologies. At its core is OpenStack, a free, open standard cloud computing platform that provides all major IaaS features and has a global footprint of over 45 million compute cores.

This is complemented by Kubernetes, the leading container orchestration platform, and Ceph, a distributed software-defined storage platform capable of holding 50 PB+ of data. We also integrate Argo for Continuous Delivery, Prometheus for comprehensive monitoring, and MAAS for managing the lifecycle of bare-metal servers.
