UltraCloud
UltraCloud is a Nix-first cloud platform workspace that assembles a small control plane, network services, VM hosting, shared storage, object storage, and gateway services into one reproducible repository.
The canonical local proof path is the six-node VM cluster under nix/test-cluster. It builds all guest images on the host, boots them as hardware-like QEMU nodes, and validates real multi-node behavior.

Scope
UltraCloud is centered on reproducible infrastructure behavior rather than polished end-user product surfaces. Some services, such as creditservice, are intentionally minimal reference implementations that prove integration points rather than full products.
Host-level NixOS rollout validation is also expected to stay reproducible: the deployer-vm-smoke VM test now proves that nix-agent can activate a prebuilt target system closure directly, without recompiling the stack inside the guest.
