### Gateways

A cluster may use multiple Gateways, each with a different load balancer IP, domains and certificates.

Since the domain certificates are stored in the gateway namespace, it is recommended to keep each
gateway in a dedicated namespace and restrict access.

For large-scale gateways it is optionally possible to use a dedicated pilot in the gateway namespace.
