# Concepts

Core ideas worth modelling before you write code. Each topic is self-contained — skim the one you need.

- **[Architecture](/docs/scaigrid/scaibunker/concepts/architecture)** — How the ScaiGrid controller, ScaiBunker workers, the storage proxy, and the Firecracker microVMs fit together.
- **[Network profiles](/docs/scaigrid/scaibunker/concepts/network-profiles)** — The five network profiles a bunker can run under — isolated, registry, allowlisted, unrestricted, transit — what they allow, who can use them, how to pick.
