Enabling cross-region private access to Amazon S3 with existing application configuration

This article explains how to enable cross-region private access to Amazon S3 without modifying existing application configurations. The solution allows organizations to maintain strict private network communications across different AWS Regions.

• Uses Route 53 Resolver endpoints to enable cross-region DNS resolution
• Allows applications to access S3 resources in remote regions over private connectivity
• Requires establishing private connectivity between AWS Regions
• Enables private DNS support for Amazon S3 in the remote region
• Configures Route 53 Resolver inbound and outbound endpoints

The solution provides improved security, performance, and cost optimization by routing S3 access through private network paths without requiring application modifications.
