Configuring VPC Endpoints for Private AWS Service Access Overview Domain expertise for configuring VPC endpoints to enable private access to AWS services without routing traffic through the internet. Covers both gateway endpoints (S3, DynamoDB) and interface endpoints (EC2, SSM, Secrets Manager, etc.) powered by AWS PrivateLink. Configure VPC endpoints To create and configure VPC endpoints for private AWS service access, follow the procedure exactly. See VPC endpoints configuration procedure . Troubleshooting Endpoint not available Check security group rules, subnet configurations, and service availability in the region. DNS resolution issues Verify DNS hostnames and DNS resolution are enabled on the VPC and that the DHCP options set has correct domain name servers. Connection timeouts Verify security group rules allow HTTPS traffic (port 443) and route tables are properly configured for gateway endpoints. Policy restrictions Review endpoint policies — default policies allow all access, but custom policies may be restrictive.
