When you first use Cloud Datastore, you must choose a location where the project's data is stored. To reduce latency and increase availability, store your data close to the users and services that need it.
Types of locations
There are two types of locations where you can store data using Cloud Datastore: multi-region locations and regional locations.
Multi-region locations provide multi-region redundancy and higher availability. Regional locations provide lower write latency and co-location with other Google Cloud Platform resources that your application may use.
A multi-region location is a general geographical area, such as the United States. Multi-region locations contain multiple regional locations. The following multi-region locations are available:
|Multi-Region Name||Multi-Region Description|
A regional location is a specific geographic place, such as South Carolina. The following regional locations are available:
|Region Name||Region Description|
* For customers using the São Paulo region, all regional product SLAs will remain in force. However, multi-region and cross-region functionality spanning North America and South America may temporarily have reduced availability or performance.
All regional locations are separated from other regional locations by at least 100 miles.
Choosing a location
You must specify a location for your project before you use Cloud Datastore, and after you select a location for your project, you cannot change it.
After you create a project, visit the Datastore Entities page and click Try it out > Create entity to set the location. The location picker menu, shown below, appears only if you have not yet selected a location.
Finding the location you chose
To find out which location you selected for your project, open the Google App Engine Dashboard in the Google Cloud Platform Console. The location information is in the upper right-hand corner of the dashboard.
