How to setup remote datacenter wordpress failover documentation/scripts?
I am trying to setup a wordpress blog network with 99.9% uptime. My experience with hosting companies is that there are hardware and network failures that can cause significant amount of downtime. So I was thinking of creating a remote hosting failover solution. Is it possible?
I have been searching for a remote (vps in Japan and US) datacenter wordpress (application and mysql database) failover documentation/scripts, but cannot find anything on the web. Ideally, the solution should be syncing both datacenters at the same time. If server A goes down, then server B will startup. Once server A is up again, server B will send its updates to server A and server A will resume. Since this will probably taxing on server A, server B might have to be 4-8 hours delayed. It is not ideal, but I have not found a solution to keep them in sync constantly.
I have searched under failover, clustering, replication, mirroring, syncing, and high availability over search engines and forums, but have not found a remote solution. I have read about dns failovers, but many have not recommended this solution.
If you have experience with a remote datacenter wordpress failover solution, please share.
