Glossary

Control plane — the coordinating layer that owns registration, scheduling and routing, billing, and residency enforcement. Customers talk only to its API.

DDDC — decentralised distributed data center. The category Thatch is in: pooling independently-owned, heterogeneous machines into one coordinated fabric.

Fabric — the pooled fleet presented as a single coordinated region.

Job — a unit of submitted work with requirements attached; the scheduler places it and it carries a state through to completion. Jobs are how the fabric schedules work internally; as a customer you submit requests to the API rather than creating jobs directly.

Node — one participating machine, running the node agent that registers it, reports capacity, health, and power, and executes scheduled work.

Node agent — the software running on a node that connects it to the control plane.

Placement — the scheduler’s decision about which node runs a given job.

Region — the jurisdictional boundary work is pinned to. See Data residency.

Residency — the guarantee that work and its data stay inside a chosen region.

Trust-minimised — the fleet is coordinated without requiring the individual nodes, or their owners, to be trusted.
