If I understand the thinking here, it's that at the default redundancy
level ('n'?) of 3, it is most likely to start getting me some scaling

So with n=3 and r=2 and w=2, the loss of two replicas due to AZ failure

Jared - thanks for the links. I'm in the same boat with Brady with weighing
deployment options in AWS.
Jeremiah - isn't EBS the only option once your data starts reaching into
the hundreds-of-gigs?

Nope, depending on how much you want to spend, you can cram up to 42TB into
a single AWS instance. Reasonably priced instances can hold 1690GB of data
on a single instance. You can see an easy to sort map over here:

Hi all -
I have some questions about how I want my Riak stuff to work - I've already
asked these questions of some Basho people and gotten some answers, but
thought I would toss it out into the wider world to see what you all have
to say, too:
First off - I know 5 instances is the magic number
I'd be wary of using EBS backed nodes for Riak - with only a single
ethernet connection, it wil be very easy to saturate the max of 1000mbps
available in a single AWS NIC (unless you're using cluster compute
instances). I'd be more worried about temporarily losing contact with a
node through
+1 to what Jeremiah said, putting a 4 or 5 node cluster in each US West and
US East using MDC between them would be the optimum solution. I'm also not
buying consistent latencies between AZ's, but I've also not tested it
personally in a production environment. We have many riak-users members on
