AWS OpenSearch Domain Does Not Have At Least Three Data Nodes

Overview

This validation verifies that OpenSearch domains have been set up with a minimum of three data nodes and zoneAwarenessEnabled is set to true. The validation will not pass for an OpenSearch domain if the instanceCount is below 3 or if zoneAwarenessEnabled is set to false.

To ensure high availability and fault tolerance, it is essential for an OpenSearch domain to have a minimum of three data nodes. Deploying an OpenSearch domain with at least three data nodes guarantees the continuity of cluster operations in the event of a node failure.
