Drupal in an Enterprise environment means that you’ll have to address the issues regarding High Availability (HA) and Disaster Recovery (DR). Backups are nice, but likely won’t cut it when you have a data center or server outage on a mission critical system. How do we create a system using modern tools that will allow us to fail-over gracefully while assuring high data integrity while doing so?  

We’ll cover our approach to using ZFS snapshots and open source tools from Percona and in particular Galera clusters in MariaDB to withstand data center outages for mission critical Drupal systems.
