For a long time up to the latest version 11 documentation, there has been a recommended maximum limit of 4 nodes per cluster.
https://tomcat.apache.org/tomcat-11.0-doc/cluster-howto.html "This works great for smaller clusters, but we don't recommend it for larger clusters — more than 4 nodes or so." Are there any plans to improve this? It's a pity to have to change the architecture when going from, say, 3 notes to 8 by introducing farms. What is the next simplest free cluster to move to? Redis? Any idea how cluster farming compares with redis? What other options are there?
