If you are interested by a great and revolutionary HA solution for MySQL or even if you already have some experience with PXC and/or Galera, I invite you to attend the tutorial I will deliver in Percona Live MySQL Conference London 2012 (PLUK2012), December 3rd : Percona XtraDB Cluster in a nutshell.
Small amount of theory and a lot of exercises and examples to really tame the beast that PXC is !
A Codership engineer will also be present and happy to help me answering your questions.
Note to attendees: please bring your laptop with a recent Virtual Box installed and enough free space to store 3 VMs (+/-2G per VM). As said before, this session will be almost 100% hands on !
Last but not least, tweet the link to this blog for a chance to win a free full conference pass. Make sure to use hashtag #perconalive! Winner will be chosen at the end of the day.
