Recommended Redis cluster topology with replication

[Daniel_benchANT]

Hi guys,

I am playing with the automated deployment of replicated Redis clusters and I am struggling a bit with the recommended deployment topology, i.e. the master and slave distribution per node.

I'd like to have to have a fully replicated three node cluster, i.e. 3 master instances and 2 replica instances per master instance. 

Should every master instance and every replica instance reside on a dedicated node or should they reside together on the same node.

So for example, if I want to deploy a fully-replicated 3 node cluster, I see two options:

1. spawning three nodes and putting per node: 1 master instance + 2 replica instances
2. spawning nine nodes where 3 nodes are master nodes and 6 nodes are replica nodes

Thanks a lot for any advice on this topic!
