The MySQL marketplace has quite a few High-Availability (HA) solutions such as Continuent Tungsten, Galera/XtraDB Cluster, various MySQL script/patch solutions, and RDS with multi-zone HA. Providing seamless, automatic failover with zero down-time maintenance in one data center can be challenging, but extending that same functionality across multiple sites in different continents truly makes that a difficult goal to achieve. Continuent has perfected various cluster solutions over the years and we have many customers running them in production, with more currently converting from Galera or RDS to our solutions.
