# reef-storage Low-cost, data-secure, runtime-independent **S3-compatible** storage substrate for backup and large volumes that can tolerate slow access. Scaleway provides the S3 capability. This reef does **not** host a rail and does not operate the object store. It names the boundary and holds non-secret attributes. - Declaration: `declarations/reef.yaml` - Attributes: `substrate/object-stores/` - Join: `reef:storage/#` from `resource-control`
