We are planning to use ELK stack for logging.  
If we are installing Elasticsearch in a server, then how do I decide how much RAM and disk space will be required as Elasticsearch stores and indexes the logs.

Answers and reference URLs will be very helpful

[This is the classic guide](https://thoughts.t37.net/designing-the-perfect-elasticsearch-cluster-the-almost-definitive-guide-e614eabc1a87), but it's getting a few years old.

These are some good resources.

This is about how to sizing and deploy Elasticsearch in Elastic Cloud, but it is best practices you can build your own cluster the same way using the same approach / benchmarks
