CentOs vs Ubuntu for elastic

Hi Support,

I just need to confirm that, is there any difference / any issue/performance-related issue between CentOs - 7 and Ubuntu 18.04 LTS.

UAT Testing was on CentOs, now the Production setup is in Ubuntu.

So will it be any impact on production if we go with the Ubuntu server?

Thanks in advance.

Personally do not see any differences on the chosen OS'es in the clusters I have seen.
I find the firewall ufw easy to work with with several API's and also setting up the clusters with remote scripts to be a bit more easy.

I think if you set up the right settings for memory and the best practices in the documentation for going to production. The settings can be found here: https://www.elastic.co/guide/en/elasticsearch/reference/current/important-settings.html

Thank you
