Clustering a Grails 3.x app (not DB, just the app!)

[Bahman Movaqar]

I've started re-writing a web application in Grails since just a few days ago; it's a classic Spring MVC application: security, session (redis), FreeMarker and JPA (PostgreSQL). In its current state, it's easy (thanks to Spring session) to fire up a new instance of the application to help overloaded instances --given that only one PG and one redis server is used. 

Now I'm wondering if there are special precautions I should observe for the Grails version to be like that[1]?  Is using a redis-backed session store is enough[2]?

I'd appreciate any hints on this.

[1] I'm not sure what it is called; but I guess application-level-clustering would be a good enough new buzzword :-)

[2] Like this: https://grails.org/plugin/redis-database-session

Since grails 3 is based on spring boot you can just use spring session.

I wrote up a post on how to use it - http://blog.agileorbit.com/2015/09/04/Spring-Session-Redis-Grails-3.html

Many grails specific plugins don't need to be created anymore since you can easily use what's provided by boot.

Hope that helps!
