Ceph is an open-source software platform designed for distributed storage systems. It provides scalable and reliable storage solutions for various data types, including block, object, and file storage. Ceph is often used in cloud computing environments and can manage large amounts of data across multiple servers. The architecture of Ceph is based on a cluster of nodes that work together to store and retrieve data efficiently. It uses a unique algorithm called CRUSH to distribute data evenly across the cluster, ensuring high availability and fault tolerance. This makes Ceph a popular choice for organizations looking to implement robust storage solutions.
