Server Load Balancer (SLB)Content
Target customers: All customers. Feature description: The ALB LCU reservation feature allows you to pre-allocate a specific number of Load Balancer Capacity Units (LCUs) to an ALB instance, establishing a guaranteed minimum level of performance. Your ALB instance will continue to auto-scale elastically based on traffic demands. However, with LCU reservation configured, its performance capacity is guaranteed to never drop below the number of LCUs you have reserved.
