The results in the survey were very favourable to Galera Cluster providing high availability for MySQL and OpenStack components. Galera Cluster with MariaDB received second place, Galera with MySQL fifth place and Galera with Percona Server (Percona XtraDB Cluster) sixth place. Altogether Galera Cluster with three different MySQL variants is clearly the most popular database high availability solution for OpenStack users.

This survey report analyzes respondents who completed or updated the survey during a two-week window in September 2015, and questions represent some modifications from prior surveys in keeping with the evolution of the OpenStack platform. This survey represents a snapshot of 1,315 users and 352 deployments, provided voluntarily. The User Survey is not a market survey and does not express …

CONCLUSIONS

MySQL/Galera was able to outperform Aurora in all tests — by execution time, number of transactions, and volumes of rows managed. Also, scaling up the Aurora instance did not have the impact I was expecting. Actually it was still not able to match the EC2 MySQL/Galera performance, with less memory and CPUs.

In light of the tests, the recommendations consider different factors to answer the question, “Which is the best tool for the job?” If HA and very low failover time are the major factors, MySQL with Galera is the right choice”.

READ THE FULL STORY AND INVESTIGATION

Relational databases are ubiquitous in OpenStack: practically every OpenStack service stores its critical metadata in a database, and the MySQL family of databases is the de-facto standard for OpenStack relational data storage. The need for high availability for these relational datastores is obvious. Galera is the default multi-master strongly-consistent replication facility for highly-available relational data in OpenStack. In this webinar, we are joined by independent OpenStack expert Florian Haas to illustrate the ins and outs of Galera for OpenStack.

Speaker bio: Florian Haas is an open source software specialist, experienced technical consultant, seasoned training instructor, and frequent public speaker. He has spoken at conferences like LinuxCon, OSCON, linux.conf.au, the OpenStack Summit, the MySQL Conference and Expo, and countless user and meetup groups across the globe.
