Azure's global infrastructure is the physical foundation that powers all Azure services. Understanding how it's organised helps you design applications that are resilient, performant, and compliant with data residency requirements.
Azure groups its infrastructure into geographies — discrete markets defined by geopolitical boundaries. Each geography contains one or more regions and is designed to meet data residency and compliance requirements.
Examples of geographies:
| Geography | Regions |
|---|---|
| United Kingdom | UK South, UK West |
| Europe | North Europe (Ireland), West Europe (Netherlands) |
| United States | East US, West US, Central US, and many more |
| Asia Pacific | Southeast Asia (Singapore), East Asia (Hong Kong) |
