So as I understand it if a Cluster Master goes down it brings down the entire cluster, I am currently going through the planning phase of our hosted solution setup and my major worry is that if we build our cluster and the CM goes does down it means EVERYONE goes down OR if there is a network level outage that will also bring down the enter cluster.
What do you guys do in terms of redundancy? my though was to setup multiple clusters (or its really actually load balancing) over different data centres. So at least should one DC go down or one CM go down the customers on the other cluster are not affected.
Any ideas or best practices?
