Re: [jgroups-users] EXT: Re: (no subject)

Well, that's just it.  if a karaf container on the primary server fails, then it switches over to the backup container on the failover server.  

That's failover, application.  You're knowledge on JGroups is far beyond mine, but, I think this is a perfect fit for JGroup Cluster instrumenting an application level failover, 

Let's say these 2 karaf containers 1 on box a, 1 on box b, karaf container on box 1 crashes leaves the cluster, and then the one on box b takes over, no loss.

I don't know, sounds like a good match to me, but, what do I know

What do you mean by failover?

JGroups provides clustering, ie. discovering and joining a cluster, sending messages between members of a cluster and getting notifications when members join or leave (or crash).

This could be used for example to provide multiple JBoss Fuse servers, that possibly even share state.

Failover, however, in my opinion, is something between clients and a
server: when the server dies (or leaves the cluster), clients are notified and re-connect ('fail over') to a surviving server.

Infinispan, for instance, has a client-server protocol (HotRod) which includes the list of servers, so that clients can failover to another server should the server they're connected to fail.
