Hello, I wonder if anyone on this ML has used ActiveMQ in an environment where the software must failover to a disaster recovery (DR) site. It's quite a different thing from failing over because the primary machine has died.
I realise that AMQ does provide failover but it looks to me like it is designed to work soley within a site, to gaurd against machine failure. This is very good and for many envs this is probably all that is needed. However, some High Availability (HA) envs have to cope with the data centre being knocked out. When that happens all the machines in that building become unavailable and the organisation is forced to switch to machines at their DR site. DR sites are usually connected to the primary site via a WAN. Unlike the network used at the primary, the WAN will be operating over far greater distances and will thus have much higher latency. Connections may also be unreliable, e.g dropped from time to time. Ha anyone any experience of developing HA systems in such an environment? Whilst using AMQ?
