Explanation
When an administrator enables NDB Multi-cluster functionality, certain components are deployed or reconfigured to support the distributed environment. HAProxy (High Availability Proxy) is a critical component that manages load balancing and secure communication across clusters. In a multi- cluster setup, HAProxy is deployed on a dedicated VM to ensure efficient traffic distribution and high availability for NDB services, such as API calls and GUI access, across the clusters. This dedicated deployment enhances scalability and resilience.
