I would like to know the how many Public IP addresses need to deploy my cluster in AWS.  
In my cluster, there are

- 2 data nodes for Hot data
- 2 data nodes for warm data
- 3 Master Nodes
- 2 Logstash

Feel free to suggest me for best practice and any recommendation welcome.

I believe that with a reverse proxy you could succeed. For example with nginx.
