Webinar Replay: How to Migrate to Galera Cluster for MySQL & MariaDB

Watch the replay of this webinar with Severalnines Support Engineer Bart Oles, as he walks us through what you need to know in order to migrate from standalone or a master-slave MySQL/MariaDB setup to Galera Cluster.

When considering such a migration, plenty of questions typically come up, such as: how do we 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?

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

It has some characteristics that make it unsuitable for certain use cases, however, 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.

Check out this walk-through on how to migrate to Galera Cluster for MySQL and MariaDB.
