OpenShift Data Foundation (ODF) is a Software Defined Storage solution that manages and stores large amounts of data across multiple environments in a scalable, efficient, and secure manner. It provides a unified view of data from different sources, including databases, file systems, and cloud storage. With ODF, organizations can manage structured and unstructured data from multiple sources, and gain insights from it through analytics and machine learning enabling them to build a modern data infrastructure that is flexible, agile, and cost-effective.

Under the hood, ODF utilizes Ceph as the underlying distributed storage system. Ceph stores the data and manages data replication and distribution across multiple nodes in the storage cluster, ensuring high availability and data redundancy. Rook, integrated with ODF as a storage orchestrator, automates the deployment and management of Ceph within the Kubernetes cluster. Rook handles tasks like data replication, scaling, and fault tolerance, relieving administrators from dealing with these complexities.
