helloV's answer is 100% valid as of the time when it was written (Oct 30).

Just 2 days later, on November 1, 2017, AWS announced Direct Connect Gateway, a new feature to allow customers using any AWS Direct Connect Location to use their Direct Connect connections to access any Virtual Private Cloud deployed in any AWS Regions (except AWS China Region).

For more information see the news: AWS Direct Connect Enables Global Access.

More details are available in AWS documentation: Direct Connect Gateways User Guide

It is possible if all regions are in US. From: AWS Direct Connect – Access to Multiple US Regions

You can provision a single connection to any Direct Connect location in the United States and use it to access all four of the AWS Regions in the US:

  • (US East (Northern Virginia)
  • US West (Northern California)
  • US West (Oregon)
  • AWS GovCloud (US)

The document was dated 19 DEC 2013 when US East (Ohio) was not introduced. So multiple regions supported includes US East (Ohio) too.

  • Fine print, this appears to carry an additional cross-region transport charge of $0.03/GB back to the region where the Direct Connect connection is physically provisioned. – Michael - sqlbot Oct 30 '17 at 17:58
