When Integration Runtimes are configured with the default “Auto Resolve” region setting, Azure may automatically provision them in a region different from the data sources or sinks. For example, an environment deployed in West Europe may run pipelines in US East. This causes unnecessary cross-region data transfer, increasing networking costs and pipeline latency. The inefficiency often goes unnoticed because data transfer costs are billed separately from pipeline compute charges.
ADF billing includes charges for pipeline activity runs, data movement, and Integration Runtime compute. Data transferred between Azure regions incurs additional network egress costs, which can exceed compute costs when workloads are large or frequent.
