EnterpriseDB's CloudNativePG reaches CNCF Incubation

EnterpriseDB (EDB) said CloudNativePG (CNPG), a Kubernetes operator for Postgres that the company created, has reached Incubation status with the Cloud Native Computing Foundation (CNCF). The development came less than a week after EDB completed its acquisition of Altinity, and the company linked it to enterprises running critical data on Kubernetes.

CNCF Incubation requires stable, versioned APIs and production use, which CNCF verifies by interviewing real users of the project. For enterprises running Postgres across hybrid environments or moving critical data to sovereign infrastructure, Incubation is independent confirmation that CNPG runs in production. Intesa Sanpaolo, Italy's largest bank, manages more than 500 Postgres instances on CNPG.

CNPG manages the full lifecycle of Postgres clusters through a declarative manifest that runs on any cloud or on-premises environment. Self-healing, automated failover, rolling updates, and continuous backup with point-in-time recovery handle work that was previously manual. EDB's Klio, donated to the CNPG community, streams write-ahead log (WAL) data continuously and keeps a local copy beside each cluster, so restores run at disk speed.

Klio encrypts data in transit and at rest with rotatable keys the customer controls. Backups can be kept on local volumes, S3-compatible storage, or both, and a single Klio server protects many clusters. The Altinity Kubernetes Operator for ClickHouse software, maintained since 2019, was the first Kubernetes operator built for real-time analytics. Both operators follow the same declarative Kubernetes pattern, which serves as the basis for one control plane.

EDB is previewing two enterprise offerings planned for general availability by the end of 2026: an EDB distribution of Klio with certified images, enterprise support, and long-term-support releases, and an EDB Postgres AI Plugin for CloudNativePG that adds transparent data encryption to open source CNPG without an operator swap. The two databases are brought together in EDB Postgres AI (PG AI), a multi-model data layer running natively on Kubernetes.

“The open, sovereign future runs on Kubernetes. Never is this more true than in the financial sector, where data agility across transactional and analytical workloads is critical,” said Max Romanenko, CTO, EDB. EDB plans to introduce integrated enterprise ClickHouse capabilities in Q4 2026.
