Server Load Balancer:ALB resource plans

Last Updated:Jun 10, 2025

Application Load Balancer (ALB) supports subscription resource plans. After an ALB resource plan takes effect, it automatically offsets the Load Balancer Capacity Unit (LCU) fees and instance fees of ALB. ALB resource plans are more cost-effective than the pay-as-you-go billing method. You can specify the time when you want your resource plans to take effect. ALB resource plans are suitable for enterprises on a fixed budget.
