Migrating to Galera Cluster for MySQL and MariaDB

Galera Cluster is a mainstream option for high availability MySQL and MariaDB. And though it has established itself as a credible replacement for traditional MySQL master-slave architectures, it is not a drop-in replacement.

While Galera Cluster has some characteristics that make it unsuitable for certain use cases, most applications can still be adapted to run on it.

The benefits are clear: multi-master InnoDB setup with built-in failover and read scalability.

But how do you migrate? Does the schema or application change? What are the limitations? Can a migration be done online, without service interruption? What are the potential risks?

In this webinar, Severalnines Support Engineer Bart Oles walks you through what you need to know in order to migrate from standalone or a master-slave MySQL/MariaDB setup to Galera Cluster.
