+### Cloud native architecture
+
+The CYBERTEC PG Operator is designed from the ground up with a **cloud-native approach**:
+
+- **Declarative configuration** via Kubernetes CRDs - completely in the spirit of *Infrastructure as Code*.
+- **Self-healing and automation** through Kubernetes and [Patroni](https://github.com/zalando/patroni), including automatic failover, leader election and rolling updates.
+- CI/CD-friendly**: No direct access to the Kubernetes API required - ideal for GitOps workflows and automated deployments.
+- Platform-independent**: Runs on any Kubernetes-compatible infrastructure - whether public cloud, on-prem or hybrid.
+- API-driven control**: Patroni provides a REST API to query the cluster state and trigger failover - essential for dynamic, service-oriented architectures.
+
+This architecture forms the basis for a modern, highly available and scalable PostgreSQL platform in the cloud era.
