title: Redis: Does replication without Multi-AZ makes sense?
body: <p>On creating a Redis cluster you can enable replication and alternatively the Multi-AZ feature. My question is: Is there any benefit to <strong>not enable</strong> it? If you are using replication I suppose that you always want the automatic failover of the Multi-AZ as it is explained <a href="http://docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/AutoFailover.html" rel="nofollow">here in the docs</a>. After some searching I even found that's also free of charge. Am I missing something? </p>
