Tomcat Clustering or F5?

We have 2 IIS servers connected to a 2 server Coldfusion 2016/Tomcat Cluster, The IIS servers hang off our F5 via a vip/pool combination.

 

We have health monitors against each IIS Server.

 

In theory if a Tomcat member server goes down the Apache Connector in IIS selects the next available box via the workers.properties file.

 

My question is, is there anything gained by having the workers.properties file just point to an F5 vip with a pool of the 2 tomcat servers, with ColdFusion health monitors on the pool? Eliminate the tomcat cluster and let F5 do all the work?

 

All thoughts on this are appreciated.

 

Thanks!

    Add only one node into worker properties, delete others.

    worker.balancer.balance_workers=node1
worker.node1.reference=worker.template
worker.node1.host=<"Virtual Server IP">
worker.node1.port=<"Virtual Server Port">
worker.node1.activation=A
