Hi,
Right now I run a 1-server hyperconverged hosted-engine deployment. Other
than requiring systemwide downtime to perform host maintenance, it has
worked fairly well for me over the past few years. However, after a
couple power and upstream-network outages, there have been questions about
the ability to "distribute the load", so to speak. Considering what our
workload is (main git repo, wiki, email list + archives, etc), it can't
easily be distributed by a periodic resync and DNS round robin like a
static web site.
To solve this distribution problem I was wondering if there might be some
way to deploy a handful of physical servers in different geographic
locations that work together to create an HE environment for guest VMs?
My initial fear would be that it would require dedicated 1Gb (or higher)
between the sites to move data? Let's say we do NOT have that level of
connectivity.
I saw something about geographic replication in Gluster? But that would
seem to be more about replicating a local cluster to a remote cluster?
I suspect the answer is: no, a cluster must all be physically co-located.
But I figured I would ask the experts.
Thanks all for your insights.
