"Ceph: The De Facto Storage Backend for OpenStack"

By: Sebastien Han

For more than a year, Ceph has become increasingly popular and saw several deployments inside and outside OpenStack. The community and Ceph itself has greatly matured. Ceph is a fully open source distributed object store, network block device, and file system designed for reliability, performance, and scalability from terabytes to exabytes. Ceph utilizes a novel placement algorithm (CRUSH), active storage nodes, and peer-to-peer gossip protocols to avoid the scalability and reliability problems associated with centralized controllers and lookup tables. Since Grizzly, the Ceph integration gained some good additions: Havana definitely brought tons of awesome features. It also made the integration easier and definitely removed all the tiny hacks. All these things, will certainly encourage people to use Ceph in OpenStack. Ceph is excellent to back OpenStack platforms, no matter how big and complex the platform.. The main goal of the talk is to convince those of you who aren't already using Ceph as a storage backend for OpenStack to do so. I consider the Ceph technology to be the de facto storage backend for OpenStack for a lot of good reasons that I'll expose during the talk. In this session, Sebastien Han from eNovance will go through several subjects such as (depends on the time that I'll get): Quick Ceph overview (for those of you who are not familiar with it) Quick state of the integration with OpenStack (general state and Havana's best additions) Quick cinder drivers overview and comparisons Building a Ceph cluster - general considerations Use cases and design examples (hardware harware hardware) Achieve HA with Ceph Operations: backups, monitoring, upgrades Tips and best practices
