Hello Elastic Team/Community

I’m currently in the process of designing a cluster that has 3 nodes.  
I was a bit confused on how will the requests be sent to the cluster.  
Should I be targeting the master node? Or split my request to the 3 nodes? And if I do split, what happens if one node is down and I’m sending requests to it?  
Should I have a zookeeper on top or a load balancer to ensure I’m not sending requests to the node that’s down?  
Appreciate your time!

Hi @Rayyanalbaz Welcome to the community and thanks for trying elasicsearch.

[Here](https://www.elastic.co/guide/en/elasticsearch/reference/current/high-availability-cluster-small-clusters.html#high-availability-cluster-design-three-nodes) is an excellent paragraph (and Page) on your topics.

The [rest of the page](https://www.elastic.co/guide/en/elasticsearch/reference/current/high-availability-cluster-small-clusters.html#high-availability-cluster-small-clusters) on resilience for small clusters is very good to read
