alb Average connection duration

Hello,

Regarding the LCUs for the Amazon Application Load Balancer, connection duration is not related directly to the LCUs for pricing. It would assist with determining your highest LCU if you know how much data the connection was passing and the durations of that connection.

The LCUs that are used for pricing are the following: New connections Active connections Processed bytes Rule evaluations

Hope this helps, here is AWS public pricing for ALB. Some additional context for the "duration" computation can be found in pricing example #3 https://aws.amazon.com/elasticloadbalancing/pricing/?nc=sn&loc=3
