The circuit is a minimal distributed operating system that enables programmatic, reactive control over hosts, processes and connections within a compute cluster.

Circuit API provides a dynamic hierarchical view of a compute cluster.

The circuit is unique in one respect: Once a circuit cluster is formed, the circuit system itself cannot fail—only individual hosts can. In contrast, comparable systems (like CoreOS, Consul and Mesosphere) can fail if the hardware hosting the system's own software fails.
