Load Balancer Capacity Unit Reservation Calculator

The LCU reservation calculator uses data based on historical workloads AWS observe and may not represent your specific workload.
For more accurate estimation based on your actual traffic, please use the ELB console Historic reference based estimate capability to estimate.
