Description

Introduction

Ceph is a powerful open-source distributed storage system designed to provide highly scalable object, block, and file storage in a single unified platform. Its architecture is fault-tolerant, self-healing, and designed to handle petabytes of data while maintaining high availability and performance. Ceph is widely used in cloud infrastructures, data centers, and large-scale enterprise environments for storage management. By using the Ceph storage cluster’s components, users can efficiently store, access, and manage data across different workloads, from object storage for web applications to block storage for virtual machines. This course covers the essentials of Ceph, from its architecture to advanced configuration, ensuring that you gain comprehensive knowledge of deploying and managing Ceph clusters.

Prerequisites

• Basic understanding of distributed systems and storage technologies.
• Familiarity with Linux systems and command-line operations.
• Knowledge of networking and storage concepts, especially block and object storage.
• Familiarity with Kubernetes and containerized environments (optional).
• A running Linux environment or VM for experimenting with Ceph installations.
