When a ztunnel receives traffic (authenticated or not) from a workload, it will forward that traffic to the Waypoint proxy **after** applying any `TRANSPORT` layer policies (i.e. `Authorization`s). Thus, if the destination workload has at least the equivalent of a `STRICT` `PeerAuthentication`, unauthenticated traffic will be rejected before it reaches the Waypoint proxy. If the effective policy is `PERMISSIVE` (the default), the ztunnel will open a vanilla TLS HBONE tunnel (NOTE: this is...

### Install Control plane

This can run in any cluster. A mesh should have at least one cluster should run Pilot or equivalent XDS server,
and it is recommended to have Pilot running in each region and in multiple availability zones for multi cluster.
