When you sign up for an Oracle Cloud Account, you must select a Data Region, which is a geographic region that contains one or more Oracle Cloud data centers.
When deciding upon a default Data Region, you should consider:
The location of the Data Region.
Ideally, the data region should be as close to your cloud service users as possible. See Data Regions for Platform and Infrastructure Services for a world map of Oracle Data Region locations.
The services available in each Data Region.
Not all cloud services are available in every Data Region. If you are interested in using a specific Oracle Cloud Service, see Data Regions for Platform and Infrastructure Services, and review the table of services below the map. It lists all the Cloud services and indicates the Data Regions where each service is available.
Any restrictions or guidelines for the country in which you reside.
For some specific countries, you might have to select a specific data center or keep in mind certain restrictions. See Data Regions for Platform and Infrastructure Services, and review the notes at the bottom of the page, which list the additional considerations when selecting a data region.
