Elasticsearch 7 and Elastic Stack - In Depth and Hands On! - Choosing Your Cluster's Hardware

The video tutorial provides guidance on setting up Elasticsearch production indexes, focusing on hardware requirements. It emphasizes the importance of RAM, recommending 64GB per machine, with 32GB for Elasticsearch and 32GB for the OS and disk cache. It advises against exceeding 32GB for Elasticsearch to avoid inefficiencies. The tutorial also highlights the need for fast SSDs and proper IO schedulers, while noting that CPU is less critical. A fast network is essential due to data replication. Local SSDs are preferred over network-attached storage. For cloud setups, medium to large configurations are recommended to balance performance and cost.
