title: How to select Topic Vs Queue
body: <p>When we design the application how to select Topic/Queue type implementation.<br>
  I am aware of,<br>
  a) If more than one consumer use the message then use Topic<br>
  b) If only one consumer then use Queue</p>
  
  <p>Please provide any more points need to be considered?<br>
  For example, concurrency, message persistence, load balancing, anything else?</p>
  
  <p>Thanks.<br>
