When traffic moves between services in the same region, it travels over Amazon’s private fiber network rather than the public internet. This ensures that the application remains resilient even if a specific partition or region experiences an outage.
Understanding Endpoint Policies for AWS Service Control
Regions act as physical data centers located around the world, while partitions separate logical groups of services, such as commercial entities, government agencies, or military departments. In contrast, an Interface endpoint creates an elastic network interface with a private IP address that connects directly to the service via AWS PrivateLink.
Instead of connecting to a generic global address, every API call is routed to a unique URL that corresponds to the service, the region where it operates, and sometimes the partition or account configuration. A typical string follows the format `service.

Operational Benefits and Network Isolation One of the primary reasons for utilizing these specific addresses is to keep traffic within the AWS global network backbone. The latter is preferred for services that do not support gateway routing, providing secure connectivity without requiring a public IP address.
