Counterpoint: you can run a single node elastic instance (and add more later), and 32G isn’t the size of memory you need, it’s the largest heap on a node you should have. (IE; it’s the sweet spot because more than 30.5GiB of Heap and Java will start using 64bit pointers). 50% of your system memory should be Heap, so realistically the sweet spot for VMs is actually 64GiB of memory for each node. I wrote a lot of these best practices as notes years ago: https://dijit.svbtle.com/elasticsearch-notes https://dijit.svbtle.com/elasticsearch-notes
