However, if a request needs a certain identity that we have not fetched yet, it will be immediately requested.

Ztunnel additionally will handle the rotation of these certificates (typically 24hr expiration) as they approach expiry.

## Telemetry

the certificates are persisted to disk, rather than kept in memory like in the standard Kubernetes deployment.

## Certificate Rotation

The agent also handles rotating certificates near expiration. It does so by triggering a callback from the `SecretManager` to the SDS server

    - **Pilot** - Responsible for configuring the proxies at runtime.

    - **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.
