You can use Percona XtraDB Cluster in AWS environments. We often get questions about how best to deploy it, and how to optimize both performance and spend when doing so. I decided to look into it with some benchmark testing.

I chose to include this group only two solutions: Galera and RDS Aurora. I’ll use the term “Galera” generically: it covers Galera Cluster, MariaDB Cluster and Percona …
