# Ephemeral Storage

**Ephemeral Storage** (referred to in the URZ context as *flüchtige Zwischenspeicherung*) is a technical process where data is temporarily cached in memory or on disk (short-term storage) for the sole purpose of facilitating real-time transmission, without being committed to permanent storage or the intent of permanent archival.

## Application in Jitsi Meet
In the context of the [[jitsi-meet]] service at Universität Greifswald, ephemeral storage is used for:

- **Stream Transmission**: Audio and video data streams are temporarily cached to ensure smooth delivery to all participants.

### Privacy Implications
- **Non-Persistence / Privacy Boundary**: Because this storage is transient and not permanent, the URZ specifies and guarantees that no "permanent recording" of conferences or individual sequences takes place.
- **[[gdpr-compliance]] Alignment**: This technical approach minimizes the amount of personal data stored long-term/permanently, supporting the principle of data minimization and reducing the risk associated with data breaches of recorded sessions.
