Why Is the Traffic of AAD Inconsistent with That of ELB?

AAD collects statistics on the peak traffic of seconds within a period of time, in bit/s. ELB collects the average traffic within a period of time. Therefore, the ELB traffic statistics are smaller than the AAD traffic statistics.

Note that if the inbound traffic exceeds the DDoS service bandwidth, traffic limiting is triggered. It's essential to adjust the service bandwidth in accordance with the real-world service traffic.

You can view the AAD service bandwidth on the AAD Console.
