AWS Technical Essentials Practice

Applications that handle spikes in request volume benefit most from using a Load Balancer because it dynamically distributes incoming traffic across multiple servers. This capability ensures that the application remains responsive and can accommodate sudden increases in workload without degradation in performance. Load balancers help to maintain high availability and reliability by routing user requests to the most appropriately capable server, which is crucial during times of high demand.

In scenarios where there are unexpected surges in usage, such as during promotional events or peak usage hours, a load balancer can effectively manage this influx by balancing the load and preventing any single server from becoming a bottleneck. This ensures that users experience consistent application performance and minimizes the risk of server overloads that could lead to outages.

Applications requiring static content delivery do not heavily rely on load balancing, as such content can often be served efficiently from a single point. Similarly, applications with low traffic may not need the resource allocation offered by load balancers, as traditional server deployment suffices for handling their minimal load. Finally, applications that do not require redundancy would not benefit from a load balancer, as redundancy is a key aspect of load balancing to ensure availability and fault tolerance. Thus, the role of a load balancer is crucial for managing variable and high-volume traffic effectively
