securing vertica internode communications - ipsec

Hi community,


Interested in anyone that has looked in to securing internode communications in a Vertica cluster. We are deploying to AWS and as a security requirement would like to see all node to node comms encrypted.


We are exploring using IPSec via Strongswan to handle this. Some tests show us that under load, we get intermittent spread communication failures.


Our anticipated cluster size is in the 35 - 50 node range.


Any tips, tricks, insights, or ideas we are missing?
