Cloudian

Cloudian is an enterprise data storage company that provides software-defined, S3-compatible object storage platforms for on-premises (on-prem) and hybrid cloud environments.

• Software-defined object storage platform for unstructured data (data storage)
• S3 API-compatible storage for private, hybrid, and multi-cloud deployments (cloud storage)
• Scalable, cluster-based architecture on industry-standard hardware (infrastructure software)
• Data protection, durability, and policy-based Data Lifecycle Management (DLM) features (data management)
• Integrations with public cloud services and enterprise applications for backup, archive, and analytics use cases (data infrastructure)

More About Cloudian

Cloudian focuses on enterprise-scale object storage (data storage) for organizations that manage large volumes of unstructured data such as backups, archives, media content, and analytical datasets. Its core platform is delivered as software-defined storage that can run on industry-standard x86 servers, providing a deployment model that aligns with on-prem data centers, private clouds, and hybrid architectures. The platform is typically used by enterprises, service providers, and public sector institutions that require S3-compatible storage inside their own facilities while maintaining integration paths to public cloud services.

The company’s technology centers on an S3-compatible object storage layer (cloud storage) that allows applications written for Amazon S3 APIs to interact with data stored on Cloudian clusters. This approach uses object storage semantics rather than block or file paradigms, with data stored as objects in buckets and accessed via RESTful APIs. The architecture supports features such as multi-tenant namespaces, Role-Based Access Control (RBAC), and metadata tagging, which are used to organize and govern large data sets within enterprise environments.

Cloudian’s platforms (data infrastructure) are designed to scale horizontally by adding nodes to a cluster, using distributed storage techniques to provide data durability and availability. The systems typically rely on technologies such as erasure coding and data replication across nodes and, in some cases, across sites. These mechanisms enable policy-based data protection and locality configurations, which enterprises use to align with internal resilience requirements and regulatory or data sovereignty constraints. Integration with directory services and key management systems supports authentication, authorization, and encryption use cases.

From a data management (data management) perspective, Cloudian offers lifecycle policies that can automatically move or tier data between different storage classes or to public cloud services using S3-compatible replication or tiering mechanisms. This is often used to tier colder or archival data to external cloud storage while keeping frequently accessed or regulated data on-prem. Integration with backup and archive software vendors allows organizations to use Cloudian storage as a target for data protection workflows, meeting capacity and retention requirements for virtual machines, databases, and file systems.

In marketplace and taxonomy terms, Cloudian is typically categorized under object storage, software-defined storage, and hybrid cloud data management. Its offerings are positioned for organizations that want S3-compatible storage in their own data centers, integrated with existing infrastructure and security controls, while maintaining the ability to connect to hyperscale cloud environments for extended retention, Disaster Recovery (DR), or analytics workloads.
