- Transit Gateway supports hub-and-spoke routing across many VPCs and networks.
- Direct Connect provides dedicated private connectivity from on-premises to AWS.
- Site-to-Site VPN is faster to provision and often used as backup for Direct Connect.
DNS and Private Access
- Route 53 Resolver inbound endpoints let on-premises resolve AWS private names.
- Route 53 Resolver outbound endpoints let VPCs forward selected domains to on-premises DNS.
- Gateway endpoints support private S3 and DynamoDB access.
- Interface endpoints use PrivateLink for private access to many AWS services.
