+# Use non default Azure regions
+
+Microsoft provides clouds for compliance with regional laws, which are available for your use.
+By default, Prowler uses `AzureCloud` cloud which is the comercial one. (you can list all the available with `az cloud list --output table`).
+
+At the time of writing this documentation the available Azure Clouds from different regions are the following:
+- AzureCloud
+- AzureChinaCloud
+- AzureUSGovernment
+- AzureGermanCloud
+
+If you want to change the default one you must include the flag `--azure-region`, i.e.:
+
+```console
+prowler azure --az-cli-auth --azure-region AzureChinaCloud
+```
