Geographical location has no impact on Azure costs or performance.

Selecting a region closer to the customer base can reduce latency and improve performance, but may result in higher costs due to regional pricing differences.

All Azure regions have the same pricing structure and service availability, making the choice of region irrelevant to cost and performance.

Costs can be lower in regions with less demand, but these regions may have limited service availability or higher latency for some users.

Compliance with local data residency laws is a critical factor in region selection, alongside cost and performance considerations.
