title: is latency and throughput in AWS SNS good enough to replace dedicated MQ for pub/sub?
body: <p>For a sake of HA I'm considering switching from self hosted solution (ZeroMQ) to <a href="http://aws.amazon.com/sns/">AWS Simple Notification Service</a> for pub/sub in an application. Which is a backend for an app, thus should be reasonably real-time. </p>
  
  <p>What are latency and throughput I can expect of SNS? </p>
