<a name="bobi-windows-choosing-an-availability-zone"></a>

No special considerations are required when choosing an Availability Zone for your SAP deployment on AWS. If high availability (HA) is a requirement, use multiple Availability Zones. For more information about HA, see the [SAP BusinessObjects BI Platform on AWS: HA/DR Guide for Windows](https://docs.aws.amazon.com/sap/latest/sap-businessobjects/sap-bobi-ha-dr-win.html).

See [AWS Global Infrastructure](https://aws.amazon.com/about-aws/global-infrastructure) for information about AWS Regions and Availability Zones.
