Overview of this book

Ceph is a unified distributed storage system designed for reliability and scalability. This technology has been transforming the software-defined storage industry and is evolving rapidly as a leader with its wide range of support for popular cloud platforms such as OpenStack, and CloudStack, and also for virtualized platforms. Ceph is backed by Red Hat and has been developed by community of developers which has gained immense traction in recent years. This book will guide you right from the basics of Ceph , such as creating blocks, object storage, and filesystem access, to advanced concepts such as cloud integration solutions. The book will also cover practical and easy to implement recipes on CephFS, RGW, and RBD with respect to the major stable release of Ceph Jewel. Towards the end of the book, recipes based on troubleshooting and best practices will help you get to grips with managing Ceph storage in a production environment. By the end of this book, you will have practical, hands-on experience of using Ceph efficiently for your storage requirements.

Understanding Ceph object storage

Object storage cannot be directly accessed by an operating system as a disk of a filesystem. Rather, it can only be accessed via API at the application level. Ceph is a distributed object storage system that provides an object storage interface via the Ceph object gateway, also known as the RADOS Gateway (RGW) interface, which has been built on top of the Ceph RADOS layer. The RGW uses librgw (RADOS Gateway Library) and librados, allowing applications to establish a connection with the Ceph object storage. The RGW provides applications with a RESTful S3 / Swift-compatible API interface to store data in the form of objects in the Ceph cluster. Ceph also supports multitenant object storage, accessible via RESTful API. In addition to this, the RGW also supports Ceph Admin APIs that can be used to manage the Ceph storage cluster using native API calls...
