Ceph S3 (Croit / RadosGW)
Waldur integrates with Ceph object storage to deliver S3-compatible buckets through the marketplace, either
via croit’s management API or directly against RadosGW Admin Ops. Each marketplace resource maps to one RGW
user with two S3 access keys, encrypted in Waldur and rotatable from the portal. The ordered ceiling is
enforced as both a user and a per-bucket quota, and storage is metered in GB-days for usage-based billing.
