Bring the cloud to your data center.
metal-stack® is a set of microservices implementing Metal as a Service (MaaS), turning a bunch of hardware into elastic cloud infrastructure. It is built to manage the lifecycles for hundreds and thousands of servers inside your on-premise data center.

State-of-the-art networking with routing-to-the-host and load balancing capabilities. Right out of the box.
Distinguishing features
Before starting development on metal-stack, we set out to create guiding principles to check our work against. These principles are the foundation of our work, reflect our motivation and present main considerations in the design of metal-stack.
Maximum performance and reliability without a virtualization layer
In combination with Kubernetes, the bare-metal approach fully eliminates the need for a hypervisor. As servers can be provisioned within minutes, hardware can be replaced quickly while Kubernetes automatically cares for your applications to run reliably all the time.
Our bare-metal design offers physical tenant separation as well as resistency against malicious attacks like Spectre and Meltdown.
The rack cabling is part of our solution, too. It is failure redundant and allows to easily scale up and extend your infrastructure with more racks as you grow.
Built for Kubernetes at heart
Together with our friends from the open-source project Gardener, metal-stack can serve as a cloud provider for delivering bare-metal Kubernetes clusters at scale. We strive for being a serious, on-premise solution to hyperscaler offerings.
