We are planning to deploy our ElasticSearch on Amazon Web Services. I noticed that there is a plugin from ElasticSearch that allows ElasticSearch to use AWS API for the unicast discovery mechanism. ElasticSearch Cloud AWS.

My questions are:

- Should I use that plugin? or it is something nice to have but not required ?
- What is the effect of not using it?

Thanks for your help and time.

If you don't use it then you need to be certain the IPs of your unicast seed hosts will never change.

I'd install it, as you also can use it for backups to S3 🙂
