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

1. If the destination has a waypoint proxy, we must send to it to the waypoint (using HBONE).
   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.

Deploying a Gateway to be used as a [Multi-network Gateway](https://istio.io/latest/docs/setup/install/multicluster/) for network `network-1`: ```yaml networkGateway: network-1 ``` ### Migrating from other installation methods Installations from other installation methods (such as istioctl, Istio Operator, other helm charts, etc) can be migrated to use the new Helm charts following the guidance below. If you are able to, a clean installation is simpler. However, this often requires an external IP migration...

Changes:
- separate namespace allows:
-- easier reconfig of just the gateway
-- TLS secrets and domain name management is isolated, for better security
-- simplified configuration
-- multiple versions of the ingress can be used, to minize upgrade risks

- the new chart uses the default namespace service account, and doesn't require
additional RBAC permissions.

- simplified label structure. Label change is not supported on upgrade.
