Since our workload is spread globally, we spread our nodes across AWS regions as well: 2 nodes per zone, 6 nodes per region (datacenter) (RF 3), 12 nodes total (except during upgrade migrations). We autodeploy into VPCs. If a region goes "bad" we can route all traffic to another and bring up a third.
Super inexpensive in that is very reliable, available and easy to manage. ml On Sun, Jan 18, 2015 at 11:50 PM, Kevin Burton <bur...@spinn3r.com> wrote: > Ah.. six replicas.
