In this chapter, we focused on scaling and tuning Elasticsearch. We started with the hardware preparations and decisions we need to make. Next, we tuned a single Elasticsearch node as much as we could and after that we configured the whole cluster to work as well as it could. We discussed vertical expansion possibilities and we learned how to monitor our cluster once it hits the production environment.
