Techniques and systems for operating a video ad exchange includes controlling an ad server to receive ad requests from viewer devices, provide ad responses to viewer devices, generate an ad delivery data file that includes information about delivery of ads to the viewer devices, and transfer the ad delivery data file to a distributed computing cloud. The technique further includes controlling an ad data infrastructure mechanism to download the cloud-based ad delivery data file into a local memory, and process the copied ad delivery data file to generate billing data. An ad data infrastructure mechanism receives a configuration file from the ad server, verifies that all items in the configuration file from the ad server were used in the generation of the first billing data, and removes non-verifiable items from the first billing data to generate a final billing data.
