Why would a customer implement soft limits within AWS services?

Implementing soft limits within AWS services is primarily aimed at ensuring resource availability and facilitating necessary scaling. Soft limits allow customers to predefine thresholds for resource usage that, when approached, trigger notifications or automated actions. This proactive approach helps organizations ensure that they have sufficient resources available for their applications as demand fluctuates.

By having soft limits in place, customers can rapidly scale their resources up or down based on real-time needs without hitting hard limits that would otherwise restrict their ability to expand. This flexibility is crucial for workloads that experience variable traffic patterns or require rapid scaling to handle peak loads.

In addition to maintaining performance guidelines, soft limits are particularly beneficial in managing the overall health and reliability of applications, as they provide a buffer zone before reaching the maximum capacity. This allows for better responsiveness during unexpected spikes in usage, leading to improved availability of services.

While performance stability, cost management, and user experience may be considerations in a broader context, the primary function of soft limits is to ensure that resources can be efficiently scaled to meet the immediate demands of the workload.
