Hello everyone, I would like to implement the elk stack for log management for a SIEM. In a production context I would like to create a cluster of 3 elastic nodes. What are your advices and best practices? 2 x node.roles: [master, voting\_only, ...] 1 x node.roles: [master, voting\_only, data ...] How many nodes for logstash? And for kibana? And what are the hardware recommendations for each node in a virtualized environment? Number of cores? RAM? How many disks? What size? Thank you very much in advance for your advice ---

Hi!! Maybe this [discussion](https://discuss.elastic.co/t/elasticsearch-large-cluster-configuration-requirments/305512) can help you. ---

Hi, Thank you @RabBit_BR. Someone who has worked on a virtualized architecture with a cluster of 3 elastic nodes, 2 logstash and 1 kibana can share his hardware configuration. CPU ? RAM ? number of disks and their sizes ? I know that the infrastructure can be evolving but I would like to have an idea. Best regards, ---
