The `v0.3` series includes support for both "public" and "private" reverse proxies.
## Entities (SQL)
`v0.3` introduces a new `frontends` table to allow the `zrok` controller to track the frontend instances that are available to any account or environment.
The following illustration shows the possibilities available.
The `*.in.zrok.io` frontend is a "public" frontend, available to all `zrok` users. Most `zrok` installations will want to have at least one public, global frontend for all public, internet-facing ingress traffic for private backend instances. In the underlying data store, the public frontend will have a row in the `frontends` table with a `NULL``environment_id`, a `type` of `public`, and a `name` set to `public` (or some other representative name).
The other two "private" frontends are configured with an `environment_id` and no `name` label. The ephemeral environment is allocated when a `zrok` frontend request is made without an account on behalf of a private share.
