Cross-region data transfer costs come from data moving between regions, so the most effective way to optimize is to keep data and related workloads as local as possible. Following data residency practices helps by keeping data in the regions where it’s required, which can reduce unnecessary cross-region replication and egress. Minimizing inter-region traffic directly lowers the amount of data that travels between regions, for example by serving users from the nearest region, using regional caches, and avoiding cross-region data paths when not needed. Placing dependent services in the same region eliminates cross-region API calls and inter-service data transfers, further cutting costs. When you combine these approaches, you reduce inter-region data movement and its associated charges, delivering the best overall cost optimization in a multi-region deployment.
