a set of control plane settings and components. While the entire mesh respects the same APIs and config,
apps may target different 'environments' which contain different instances and variants of Istio.

- Better security: separate Istio components reside in different namespaces, allowing different teams or
roles to manage different parts of Istio. For example, a security team would maintain the

   When we do this, we will want to preserve the original destination Service IP, as the waypoint can do a better job picking a backend pod than we can.
