Hi guys, I have several MySQL servers that are mission critical to operations including an API server that processes incoming Internet orders. Looking for the best option for HA. Currently using Heartbeat with MySQL replication. Open Source solutions are preferred -- as I really don't want to deal with Oracle licensing!
Also, what is the consensus on using a virtual server (Xen) for MySQL? Thought the excessive I/O would make this a serious problem. The Xen server is configured with ZFS SAN and bonded interfaces for 4gb bandwidth. If you don't have either of the above servers, what are you using to handle similar issues and how much do you pay if anything? Outsourcing is an option but from my experience if there is a problem here, it is impossible to get anyone on the phone. Also, to protect against liability, all outsources make it clear there are no guarantees on up-time. Many thanks, Nick
