High Availability (HA) Drupal

Hello all,

We are looking for web-sites which are running on the highly available Galera Cluster for MySQL.

We know that some installations are out there because there are some Drupal specific configuration parameters in Galera Cluster. But we do not know who it is.

So if your run Drupal on Galera or if you know who is running Drupal on Galera please let mee know.

Thanks,

We’re trying to ascertain the best way to achieve good redundancy in an enterprise-level utilization of Drupal. Ideally, We would like to have multiple instances of Drupal on different physical hosts/VMs. For instance, if we need to perform maintenance on one host/VM, the site doesn’t go down because there’s always another instance up, or in case of DOS attack, we’d have a better chance of sustaining because we’d have multiple instances running instead of one.

Have others been able to achieved something like this? Any advice, caveats or suggestions?
