# Concepts

> The Nullspace machine lifecycle and runtime primitives.

Nullspace machines are isolated microVM runtime environments with a small set
of explicit lifecycle primitives: Create starts a machine, Exec runs work inside
it, Hibernate pauses state for resume, reusable snapshots capture durable
1-to-many baselines, Fork branches live state into a child machine, and Destroy
tears a machine down.

  Exec --> Snapshot

  Exec --> Destroy

```

Fork is the differentiator for live branching. Reusable snapshots cover the
durable baseline case: capture setup once, then start many independent
machines later.

Private beta runs on the hosted API at
`https://api.your-nullspace-domain`. The default guest kernel follows the
Firecracker kernel lane recorded by the runtime artifacts; the opt-in FUSE lane
is documented in [Template kernel selection](../guides/template-kernel-selection).
