## Konzepte des Deployments

Obige Beispiele führen das Serverprogramm (z. B. Uvicorn) aus, starten **einen einzelnen Prozess** und überwachen alle IPs (`0.0.0.0`) an einem vordefinierten Port (z. B. `80`).

Das ist die Grundidee. Aber Sie möchten sich wahrscheinlich um einige zusätzliche Dinge kümmern, wie zum Beispiel:

* Sicherheit – HTTPS

                    if (missingParentPom != null) {
                        throw new ArtifactMetadataRetrievalException(
                                "Failed to process POM for " + artifact.getId() + ": " + missingParentPom.getMessage(),
                                missingParentPom.getException(),
                                artifact);
                    }

- For installations using Systemd MinIO service, upgrade via RPM/DEB packages **parallelly** on all servers or replace the binary lets say `/opt/bin/minio` on all nodes, apply executable permissions `chmod +x /opt/bin/minio` and process to perform `mc admin service restart alias/`.

### Upgrade Checklist
