In unclustered load balancing, which statement is true?

• A. Runtimes share data via a shared memory grid
• B. Multiple runtimes run the same application but do not share data
• C. Messages are distributed only by a third-party product
• D. There is automatic failover between runtimes

Answer: (B)

In unclustered load balancing, the key idea is that multiple runtime instances run the same application but do not share data or state with each other. Each runtime is independent, handling its own requests without coordinating or sharing memory, caches, or in-memory sessions. The load balancer simply distributes incoming requests among these independent runtimes, which means there is no built-in mechanism for automatic state synchronization or failover between them. If you need shared state or seamless failover, you'd move to a clustered setup where runtimes share data or use external mechanisms for continuity. So the statement that best describes unclustered load balancing is that multiple runtimes run the same application but do not share data.
