Overview of this book

This Learning Path takes you through the basics of Ceph all the way to gaining in-depth understanding of its advanced features. You’ll gather skills to plan, deploy, and manage your Ceph cluster. After an introduction to the Ceph architecture and its core projects, you’ll be able to set up a Ceph cluster and learn how to monitor its health, improve its performance, and troubleshoot any issues. By following the step-by-step approach of this Learning Path, you’ll learn how Ceph integrates with OpenStack, Glance, Manila, Swift, and Cinder. With knowledge of federated architecture and CephFS, you’ll use Calamari and VSM to monitor the Ceph environment. In the upcoming chapters, you’ll study the key areas of Ceph, including BlueStore, erasure coding, and cache tiering. More specifically, you’ll discover what they can do for your storage system. In the concluding chapters, you will develop applications that use Librados and distributed computations with shared object classes, and see how Ceph and its supporting infrastructure can be optimized. By the end of this Learning Path, you'll have the practical knowledge of operating Ceph in a production environment. This Learning Path includes content from the following Packt products: • Ceph Cookbook by Michael Hackett, Vikhyat Umrao and Karan Singh • Mastering Ceph by Nick Fisk • Learning Ceph, Second Edition by Anthony D'Atri, Vaibhav Bhembre and Karan Singh

Orchestration


One solution to making the installation and management of Ceph easier is to use an orchestration tool. There are several tools available, such as Puppet, Chef, Salt, and Ansible, all of which have Ceph modules available. If you are already using an orchestration tool in your environment, then it would be recommended that you stick to using that tool. For the purposes of this book, Ansible will be used; this is for a number of reasons:

  • It's the favored deployment method of Red Hat, who are the owners of both the Ceph and Ansible projects
  • It has a well-developed and mature set of Ceph roles and playbooks
  • Ansible tends to be easier to learn if you have never used an orchestration tool before
  • It doesn't require a central server to be set up, which means demonstrations are more focused on using the tool rather than installing it

All tools follow the same principle of where you provide them with an inventory of hosts and a set of tasks to be carried out on the hosts. These tasks often...
