Subject: [Engine-devel] Ideas about engine clustering?
Hello, guys:
I'm trying to make a jboss clustering environment for engine. But
felt the
difficuty too.
So I want to know if any one is working on this? I googled it and haven't
found anything.
I know there will be lots of things to do for engine migrating to
clustering
environment. I just want to know what problem need to be solved?
I would like to list the things I think that is needed to do(or solve):
1. run jboss in standalone-ha mode or domain mode.
2. add @Clustered annotation to each EJB, I think this will solve the
replication problem in cluster, probably lots of details in it.
3. QuartzScheduler problem, only one node running a scheduler is enough at a
time instead of each node running one.
4. use mod_cluster to handle load balancing.
5. postgresql clustering.
6. There should be more, but hope anyone can think about it :D
Any ideas?
Depending on your needs/interests, you might want to have a look at
ovirt-hosted-engine-setup - allows creating a VM on a host and install an
engine on that VM which will also manage the host
ovirt-hosted-engine-ha - allows configuring two such hosts for high availability
of the engine VM (in the VM level, not application level which is what you discussed
above).
Both are work-in-progress and are partially usable. Not ready for production, though.
Regards,
