I'm going to setup ELK solution on single server with 16GB RAM and 2TB space. (I'm limited only to single server). After reading this [article](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/docker.html#docker-compose-file) - i'm very confused.... Should I: - run multiple docker containers on the single machine - [described here](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/docker.html#docker-compose-file) - run one container with max resources without single-node cluster mode; - run using single-node cluster with enabled bootstrap checks. Thanks. ---

Welcome! Single-node elasticsearch is not recommended for production beacuse you will lose redundancy, reliability. You can run multiple docker containers on a single machine. ---

With one single machine, 16gb of RAM, I'd run one single instance (with or without Docker), with 8gb of HEAP allocated to it. ---

Thanks, what about: - Would you recommend the same for machine: `Intel Xeon-E 2288G - 64GB DDR4 ECC 2666MHz - 4x SSD 960GB RAID 0` ? (I mean 50% heap) - How many heap I should allocate for Logstash? - Should I use single instance mode with bootstrap-check enabled or there is another option? Thanks for your reply. ---

Since it is ELK stack, I'm not interested in reliability, ---

So I'd allocate 30gb of heap at most. But may be less if all that heap is not needed. If you are in cloud, why not just using [cloud.elastic.co](http://cloud.elastic.co) and upgrade the size as needed? ---

The customer decide to deploy self-hosted solution for the first time (to see profitability). Is there another solution to run single instance without single-node clusted or only single-node cluster? Thanks. ---

Should I use single-node discovery for production mode or other configuration? ---

I'd enable bootstrap checks indeed. ---
