Hi @amitdhanjal,
Kibana communicates via HTTP REST interface with your Elasticsearch instances. The recommended setup is to run a coordination only Elasticsearch node on the some host your Kibana instance is running. The documentation contains more information about setting up a production Kibana system: https://www.elastic.co/guide/en/kibana/current/production.html#load-balancing
Make sure that your Elasticsearch cluster has at least 3 Master-eligible nodes to prevent a single point of failure (otherwise, if you master node goes down, your complete cluster is down).
