    - **Citadel** - Responsible for certificate issuance and rotation.

    - **Galley** - Responsible for validating, ingesting, aggregating, transforming and distributing config within Istio.

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

## Repositories

The Istio project is divided across a few GitHub repositories:

In Python 3.10 there's also a **new syntax** where you can put the possible types separated by a <abbr title='also called "bitwise or operator", but that meaning is not relevant here'>vertical bar (`|`)</abbr>.
