# Architecture

The five planes of the Amfelt platform (who uses it, where it is controlled, how it is secured and observed, and where your data lives).

- [Deployment](/docs/concepts/architecture/deployment/index.md): The managed control plane, and how the agent runs on your own infrastructure.
- [Security model](/docs/concepts/architecture/security-model/index.md): How tenants are kept apart, how agents get credentials, how people and agents authenticate, and what is audited.
