Implementing custom domain names for private endpoints with Amazon API Gateway

Compute Blog

The article discusses the new feature in Amazon API Gateway that allows custom domain names for private REST API endpoints, enabling more intuitive and secure API access within private VPCs.

  • Custom domain names can now be used with private REST API endpoints
  • Supports sharing custom domain names across AWS accounts using AWS Resource Access Manager (RAM)
  • Requires setting up a VPC endpoint, ACM certificate, and Route 53 private hosted zone
  • Implementation involves four key steps: • Creating a private custom domain name • Sharing the domain name via RAM • Associating the domain name with a VPC endpoint • Creating a Route 53 alias
  • Provides a secure way for application teams to deploy and share private APIs across different AWS accounts

This feature simplifies API access by allowing stable, vanity URLs for private REST API endpoints while maintaining network security.
