title: Redis Sentinel, Standalone or Cluster, which is best for session?
body: <p>Which setup is more preferable for session using Redis?</p>
  
  <p>Since the session data will result and force all user to session if down, is it good choice to use stand alone? Since this allows quick recovery with minimum resources.</p>
  
  <p>Or having cluster will provide some more advantage?
  How are the big companies using Redis with session? Any suggestions are welcome.</p>
