EDB's Gabriele Bartolini makes the case for Sovereign DBaaS: running PostgreSQL on Kubernetes in a cloud-neutral, portable manner rather than relying on hyperscaler-managed database services. Key arguments include: managed cloud services trade control for convenience, portability via the Kubernetes Operator Pattern (CloudNativePG) gives enterprises negotiating leverage with hyperscalers, bare-metal deployments can achieve 30,000 TPS vs ~1,500 TPS on small cloud instances, and fixed CAPEX costs are critical for predictable AI workloads. Bartolini also addresses the cultural shift required, advocating for DBAs to develop T-shaped profiles by learning Kubernetes (e.g., earning CKA certification in ~one month), and warns that observability tooling trapped in proprietary provider systems undermines true independence.
