New Features

Server Load Balancer (SLB) - ALB now supports LCU reservation

LCU reservation provides a guaranteed performance baseline for your Application Load Balancer (ALB) instance. During sudden traffic spikes, ALB can immediately leverage this reserved capacity to handle the load without waiting for auto-scaling to react. This significantly enhances the availability and stability of your applications.

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.
