My Elastic Stack Looks like this:
Route53> ELB> 2x CO Nodes > 5x Master/Data Nodes
The CO (Client Nodes) take the Elastic HTTP requests as well as Kibana requests. I want to use the ReadOnlyRest plugin keeping Kibana in mind as well (still looking at the PRO options for Kibana).
The entire stack is constructed using CloudFormation Templates.
The question is - if I have to install ReadOnlyRest plugin - in which part of this ElasticStack would I install it?
If its on the CO nodes - then because I’m using Cloudforamtion, both the CO Instances will get these installations done symmetrically. IS that ok?
