App Engine is regional, which means the infrastructure that runs your apps is
located in a specific region and is managed by Google to be redundantly
available across all the zones within that
Meeting your latency, availability, or durability requirements are primary
factors for selecting the region where your apps are run. You can generally
select the region nearest to your app's users but you should consider the
location of the other GCP products and
services that are used by your app. Using
services across multiple locations can affect your app's latency as well as
App Engine is available in the following regions:
us-west2 (Los Angeles)
us-east1 (South Carolina)
us-east4 (Northern Virginia)
southamerica-east1 (São Paulo) *
* For customers using the São Paulo region, all regional product SLAs
remain in force. However, multi-region and cross-region functionality that
span across North America and South America might temporarily have reduced
availability or performance.
You cannot change an app's region after you set it.
If you already created an App Engine application, you can view the
region by running the
gcloud app describe command or opening the
App Engine Dashboard in the GCP Console.
