## Ambient mode details

Fundamentally, this component is responsible for the following:

- Sets up redirection with newly-started (or newly-added, previously-started) application pods such that traffic from application pods is forwarded to the local node's ztunnel pod.

Note: there are still some cluster roles that may need to be fixed, most likely cluster permissions

## Everything is Optional

Each component in the new installer is optional. Users can install the component defined in the new installer,
use the equivalent component in `istio-system`, configured with the official installer, or use a different
version or implementation.

three main components:

- [MeshConfig](https://github.com/istio/api/blob/master/mesh/v1alpha1/config.proto) for runtime config consumed directly by Istio
control plane components.
- [Component configuration API](https://github.com/istio/api/blob/00671adacbea20f941cb20cce021bc63cbad1840/operator/v1alpha1/operator.proto#L42-L93), for managing

- **Operator** - The component provides user friendly options to operate the Istio service mesh.

## Repositories

The Istio project is divided across a few GitHub repositories:

- [istio/api](https://github.com/istio/api). This repository defines
component-level APIs and common configuration formats for the Istio platform.

It is **beautifully designed**, **simple to use** and **highly scalable**, it has become a **key component** in our API first development strategy and is driving many automations and services such as our Virtual TAC Engineer._"
