hi sorry for the repost of basically this one > [@Multiple instance of ES and Kibana](https://discuss.elastic.co/t/multiple-instance-of-es-and-kibana/70295): > > Hi, I have some basic questions regarding ES and Kibana. Can we have more than one instance of elasticsearch and Kibana in the same server? If this question has been answered elsewhere, can someone refer me to that document? my reason for asking is that i need to protect data in a seperate ELK installation from the other ELK installed on the same (very powerfull hardware) from what i can see in the above link, this is technically feasable with using different ports, my question is about the ram and java part. if i have 64GB+ ram, will it be smooth sailing, as long as i keep the installation path etc seperate. my understanding is that i want to alot 32max ram per ELK and thus more than 65GB ram ---

Hi @ssi, it's definitely technically possible. The recommended max heap of ~32GB is per java process. I have machines with 256GB RAM that run 5 x ES, 1 x LS and 1 x Kibana and I leave about 50% of RAM to Lucene. Cheers, AB P.S. now when I know Elastic Stack better I would rather have dedicated machines at least for Elasticsearch but I _have to_ work with what was given to me 😃 ---

FYI we’ve renamed ELK to the Elastic Stack, otherwise Beats and APM feel left out! 😉 Check out [https://www.elastic.co/elk-stack](https://www.elastic.co/elk-stack) ---
