Training: Galera Cluster

Galera Cluster is a 2 days training, designed for DBAs who need to setup a HA environment based on Galera technology: a synchronous, multimaster client. After this training, the attendee will be able to use both Percona XtraDB Cluster and MariaDB Cluster, as they both are based on Galera. The training can be focused on one of these flavours, if the company wishes so.

This training covers the necessary topics to setup new clusters and upgrade existing ones, monitor them, run ordinary administration and troubleshoot problems.
