Overview

Fontana runs on Kubernetes and ships the same governed stack whether Fontana operates the host or you run it in your own environment. Production releases are pinned and immutable so upgrades are reproducible and audit-friendly. Every workspace lives in a separate cluster with its own data, secrets, and identity, regardless of deployment model.

Model Summary
Cloud deployment Managed cloud (Fontana operates the host) or customer VPC in your cloud account
Self-hosted deployment On-premises or customer-operated Kubernetes in your facility or private cloud
Dedicated host One customer per physical box; available in cloud or self-hosted arrangements

Workspace upgrades use immutable release tags and automatic pre-upgrade snapshots so you can roll back if needed. Host operators reconcile changes with the Fontana CLI; application configuration can be exported from Admin → Deployment → Export/Import. See Backup and restore for both paths.
