Have you had experience working with clustering technologies and cluster configuration?

Yes, experience with clustering technologies and cluster configuration includes setting up and managing a group of servers that work together to ensure high availability, scalability, and fault tolerance of applications.

In a Java environment, this may include:

• Using application clusters (e.g., WildFly, WebLogic) for load balancing and session management.
• Configuring distributed caches (e.g., Hazelcast, Infinispan).
• Configuring database clusters or message broker clusters.

Experience typically involves understanding network settings, synchronization of state between nodes, monitoring, and automatic recovery after failures.
