Italy’s Largest Bank Modernizes Sovereign Banking Infrastructure with EDB and CloudNativePG

Across Europe, banks are modernizing infrastructure to support cloud-native applications while maintaining strict governance over critical systems. Kubernetes has become central to that shift, enabling automation and scalability without relinquishing operational control over data environments. For financial institutions operating under strict regulatory oversight, modernization must also preserve sovereignty to ensure that infrastructure remains secure, auditable, and institutionally governed. For Intesa Sanpaolo, that transformation operates at national scale. Serving approximately 13.9 million customers through more than 2,600 branches, the bank runs one of the most extensive technology estates in European banking, including one of Italy’s largest Oracle Exadata environments supporting mission-critical services. As digital banking services expanded, provisioning timelines lengthened, replication processes strained infrastructure resources, and failover required coordinated manual intervention. These constraints limited the bank’s ability to efficiently scale Kubernetes platforms, microservices, and sovereign operational models.
