title: Spring Boot Tomcat 8 session replication
body: <p>I need to move my application into HA mode. I use Spring Boot, Tomcat 8. Right now I use plain session mechanism.</p>
  
  <p>In order to move my application into HA cluster I need to implement Session replication.</p>
  
  <p>Is it enough to implement approach described in this document <a href="http://docs.spring.io/spring-session/docs/current/reference/html5/guides/boot.html" rel="nofollow">Redis Spring Session - Spring Boot</a> or do I also need to configure Tomcat cluster ?</p>
