A key scalability challenge for almost all OpenStack components is a reliance on a single authoritative store of service related information. While not always the case, generally this comes in the form of a MySQL or PostgreSQL database. As production deployments become larger and Openstack continues to move into the enterprise space we will need to be able to scale this central store. A quick familiar method of decentralizing traditional relational databases has been through use of replications slaves. In this presentation I will explain how support for replication slaves works in Openstack and what currently uses it. I will also go over some production experience as Bluehost has been using replication slaves for over a year.
