Provision Region Considerations
App Manager restricts environments to one region per subscription. This means that once you create your first environment for a specific subscription or a service type, all other environments must be created in that region. In addition, once an environment is created in a region it cannot be moved to a different region, therefore selecting the correct region for your first environment is critical.
Like many other OCI services, if you work in multiple regions and you created your environments in region A and then switch to region B in your OCI Console, you will not be able to see the environments created in region A in the App Manager dashboard.
Before creating your first environment for your cloud service you should review your tenancy's home region, which was selected when the cloud subscription was activated:
• If the home region is the same as the expected provisioning region, you should select that region when creating your first environment in App Manager.
• If the home region is different than the expected provisioning region, you should verify the expected provisioning region with your Oracle Support or your Service Delivery Manager before you decide which region to select.
As an example, if your home region is us-ashburn-1 but your services will be provisioned in us-phoenix-1, you should select us-phoenix-1 as the region in App Manager when creating your first environment.
• Your cloud service will still work without issues even if you select the "wrong" region when creating the first environment in App Manager. The main impact will be from an administrative point of view (for example, the need to switch to a different region, that you usually work in, every time you want to view or create new environments).
