IT organizations require a disaster recovery strategy addressing outages with loss of storage, or extended loss of availability at the primary site. Applications need to rapidly migrate to the secondary site and transition with little or no impact to their availability.This talk will cover the various architectural options and levels of maturity in OpenStack services for building multi-site configurations using the Mitaka release. We’ll present the latest capabilities for Volume, Image and Object Storage with Ceph as the backend storage solution, and look at the future developments the OpenStack and Ceph communities are driving to improve and simplify the relevant use cases.
Cinder Backup was designed to easily backup your Cinder volumes to another storage platform including Ceph or Swift. Cinder volume metadata can be used to backup and restore a volume, allowing backup and restore at another site. We will also cover the community progress supporting backup from OpenStack private cloud to a public cloud.
Volume Replication was first implemented in Juno with the intent to enable volume replication services needed for HA and DR use cases. However, there were a number of challenges in the initial implementation and as such a second version has been implemented in Liberty. Volume replication is largely handled by the backend driver, with the API providing basic methods. Ceph’s new RBD mirroring functionality provides one such implementation.
