+
+This weekend we migrated the GLPI database — which previously operated inside a **StatefulSet on Kubernetes** — to **MySQL HeatWave** on Oracle Cloud, using the resources from the [Always Free](/en/blog/oracle-always-free/) program.
+
+## The previous setup
+
+EF-TECH's GLPI ran with its database on a Kubernetes StatefulSet with persistent storage via PVC. While functional, this model came with challenges:
+
+- **Manual backup management** — no automated snapshot outside the cluster
+- **Cluster resource consumption** — database CPU and memory competed with other workloads
+- **MySQL maintenance** — version updates and tuning required manual pod intervention
+- **Limited high availability** — the single-replica StatefulSet was a single point of failure
+
+## The solution: Oracle MySQL HeatWave
+
+Oracle Cloud offers a **MySQL HeatWave DB System** under the Always Free program with:
+
+- **50 GB of storage** for data
+- **50 GB additional** for automated backups
+- **Managed standalone instance** — no worries about OS or MySQL maintenance
+- **Automatic backups** — configurable retention at no additional cost
+
+Additionally, by moving out of the Kubernetes cluster, we freed up resources for main workloads and eliminated the complexity of operating a stateful database inside Kubernetes.
+
+## The migration process
+
+The migration was planned for minimal impact:
+
+1. **Provisioning** the MySQL HeatWave DB System on OCI (home region)
+2. **Exporting** the database from the Kubernetes StatefulSet using `mysqldump`
+3. **Importing** the data into the Oracle Cloud MySQL instance
+4. **Updating the connection string** in the GLPI application (ConfigMap + environment variables)
+5. **Redirecting traffic** and validating the data
+6. **Decommissioning** the old StatefulSet
+
+### Commands used
+
+Exporting data from the StatefulSet:
+
+```bash
+kubectl exec -n glpi deployment/glpi-mysql -- \
+  mysqldump --all-databases --single-transaction --quick \
+  -u root -p"$MYSQL_ROOT_PASSWORD" > glpi-backup.sql
+```
+
+Importing into MySQL HeatWave:
+
+```bash
+mysql -h <oci-mysql-host> -u admin -p < glpi-backup.sql
+```
+
+Updating the configuration in the GLPI ConfigMap:
+
+```bash
+kubectl edit configmap glpi-config -n glpi
+# Update: GLPI_DB_HOST, GLPI_DB_PORT, GLPI_DB_USER, GLPI_DB_PASSWORD
+```
+
+## Observability with Grafana
+
+With the database now running outside the cluster, we took the opportunity to set up monitoring via **Grafana** with MySQL HeatWave metrics. The main dashboards include:
+
+- **Active connections** — number of simultaneous connections to GLPI
+- **Queries per second (QPS)** — query volume and load trends
+- **Response time (latency)** — p95 and p99 of slowest queries
+- **Storage usage** — database growth over time
+- **Backups** — automated backup status and retention
+- **Alerts** — notifications for connections above threshold, delayed replication, and disk space

+
+## First results
+
+After the first hours of operation, the results are already positive:
+
+| Metric | Before (StatefulSet) | After (MySQL HeatWave) |
+|---|---|---|
+| Average query latency | ~12 ms | ~4 ms |
+| Manual backup time | ~25 min | Automatic (zero effort) |
+| Cluster resources freed | — | 2 vCPUs and 4 GB RAM |
+| MySQL maintenance | Manual | Managed by Oracle |
+
+## Next steps
+
+Throughout this week we will closely monitor the Grafana metrics to:
+
+1. Validate connection stability between GLPI (on Kubernetes) and MySQL (on OCI)
+2. Adjust alert thresholds based on the operational baseline
+3. Assess the need for tuning specific GLPI queries
+4. Document the process for replication in other environments
