Hi,

I'm sorry for the post.  
I have read all the Internet recommendation but is not so clear.

In fact I want to deploy ELK Stack and EFK Stack and for this I didn't find any "general guideline for Hardware sizing of resources" per \>\>single node\<\< vs \>\>cluster\<\<.

In my case I will have only one node (1 VM) to use for:

- ELK Stack ( Kibana, Elasticsearch, Logstash).  
vs
- EFK Stack (Kibana, Elasticsearch, FluentD).

Hardware recommendation for \>\>Single node\<\<, \>\>cluster\<\< will be:

- CPU = ?
- MEMORY = ?
- IOPs = ?

In my case I have 1VM (EFK Stack) and I try to figure out what scenario will be the best.

\*\*\*Could be possible to have a more clear detailed recommendation than ([https://www.elastic.co/guide/en/elasticsearch/guide/current/hardware.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/hardware.html)) or to have a possibility to develop a calculator for ELK Stack that will be available in order to have a better view than now.

Kind Regards,

---
