Scality, a global provider of cyber-resilient storage software, has launched two new open-source drivers designed to integrate enterprise-grade object and file storage into Kubernetes environments.
These releases mark a significant step in aligning containerized applications with scalable, standards-based storage, offering developers and IT teams greater flexibility and automation.
The newly introduced drivers include a Container Object Storage Interface (COSI) driver and a Container Storage Interface (CSI) driver. The COSI driver enables Kubernetes-native provisioning of S3-compatible object storage, supporting platforms such as Scality RING and ARTESCA. It allows developers to automate the creation of S3 buckets and manage credentials and access controls using familiar Kubernetes workflows. In parallel, the CSI driver supports file-based access to storage, allowing Kubernetes workloads to dynamically mount and manage file system volumes, while using RING S3 buckets as the underlying object store.
COSI is a standardized Kubernetes interface aimed at treating object storage – like S3 buckets – as first-class citizens in containerized infrastructure. It removes the need for manual setup, custom scripts, or proprietary integration layers. With Scality’s COSI driver, bucket provisioning and security policies are automatically handled within Kubernetes, dramatically streamlining deployment for both developers and infrastructure teams.
Erwan Girard, Chief Product Officer at Scality, emphasized that the drivers are designed with open standards at their core. “Our new COSI and CSI drivers bridge the gap between Kubernetes-native application development and enterprise-grade object storage. By leveraging standard APIs instead of proprietary protocols, we’re giving developers a seamless, transparent experience.”
Scality’s move to open source the drivers reinforces its commitment to cloud-native development and community collaboration. By making the code publicly available, the company ensures transparency, extensibility, and adaptability across a wide range of use cases – from DevOps workflows and multi-tenant SaaS platforms to complex data pipelines and AI workloads.
The COSI driver is particularly valuable for enterprises and service providers running large-scale Kubernetes environments where seamless, secure, and automated access to S3-compatible storage is essential. Meanwhile, the CSI driver allows these same users to benefit from file-based access where POSIX compatibility is needed, without sacrificing the efficiency or scalability of object storage.
Users can expect support for Kubernetes-native features such as dynamic provisioning, automated IAM-based credential management, and hybrid cloud integration – all of which are designed to reduce operational overhead and accelerate cloud-native development.
Scality’s object storage platform, RING, which is also available in an all-flash version (RING XP), forms the backbone of these integrations. The system is known for high performance, massive scalability, and robust cyber-resilience. Both new drivers are fully supported in licensed deployments of RING and ARTESCA, and can also be freely used and modified under their open-source licenses.
AzInTelecom, a government-backed cloud provider in Azerbaijan and a customer of Scality, noted the benefits of these developments. “Scality’s S3 object storage easily scales with demand, provides fast, easy access to data, and offers advanced protection to ensure uninterrupted business operations,” said Jeyhun Garayev, Director of the Information Technology Department at AzInTelecom. “The RING environment gives us the flexibility to adapt and expand our infrastructure as our business evolves.”
The COSI and CSI drivers are now available as part of Scality’s standard toolkit for existing customers and for the broader open source community.
