When running a MariaDB Cluster or Percona XtraDB Cluster, it is common to use a load balancer to distribute client requests across multiple database nodes.

  • HAproxy by HAproxy Technologies
  • IPVS by Linux Virtual Server Project
  • Galera Load Balancer by Codership
  • mysqlproxy by Oracle (alpha)

Note that there are other options out there, e.g. MaxScale from the MariaDB team, that we plan to cover in a future post.
