What technique is used to distribute demand across multiple systems?

1. Load Balancing

2. Traffic Management

3. System Optimization

4. Performance Tuning

The correct answer is: Load Balancing

Load balancing is the technique employed to distribute demand across multiple systems effectively. This method ensures that no single system is overwhelmed by too much traffic, which can lead to performance degradation or system failure. By evenly distributing the workload, load balancers optimize resource use, promote redundancy, and enhance the overall reliability and availability of services. Load balancing can be achieved through various mechanisms, including round-robin, least connections, or IP hash, depending on the specific needs of the network and the services being provided. Implementing load balancing can improve response times and help to maintain user satisfaction by ensuring that applications remain responsive and available even during peak demand periods. In contrast, while traffic management may involve some aspects of directing traffic efficiently, it typically encompasses broader strategies that might include traffic shaping or prioritization rather than the direct balancing of requests among multiple systems. System optimization often focuses on enhancing the performance of a specific system rather than distributing the load across multiple systems. Performance tuning generally pertains to fine-tuning a particular system for better operation rather than managing demand across several systems.
