contains platform-specific code to populate the
[abstract service model](https://istio.io/docs/concepts/traffic-management/#pilot), dynamically reconfigure the proxies

override some container level values in the Pilot container  ([samples/pilot-advanced-override.yaml](samples/pilot-advanced-override.yaml)):

```yaml

TODO. It is possible to add Istio-CNI later, and gradually migrate.

### 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.
