Faster Amazon Web Services cloud connections with TLS 1.3

by Kate Rodgers, Janelle Hopper, James McDuffie, and Scott Malkie | on

September 13, 2023: Over 65% of Amazon Web Services service API endpoints now support TLS version 1.3. We are continuing work to enable TLS version 1.3 on Amazon Web Services service API endpoints globally.

At Amazon Web Services (Amazon Web Services) , we strive to continuously improve customer experience by delivering a cloud computing environment that supports the most modern security technologies. To improve the overall performance of your connections, we have already started to enable TLS version 1.3 globally across our Amazon Web Services service API endpoints, and will complete this process by December 31, 2023. By using TLS 1.3, you can decrease your connection time by removing one network round trip for every connection request, and can benefit from some of the most modern and secure cryptographic cipher suites available today.

If you are using current software tools (2014 or later) including our Amazon Web Services SDKs or Amazon Web Services Command Line Interface (Amazon Web Services CLI) , you will automatically receive the benefits of TLS 1.3 with no action required on your part. This is because Amazon Web Services services will negotiate the highest TLS protocol version that your client software supports. If you want to continue using TLS 1.2, you will still have full control through your client configurations. Amazon Web Services will retain support for TLS 1.2, in addition to TLS 1.3, into the foreseeable future. Meanwhile, here’s the latest information on the on-going deprecation of TLS 1.0/1.1 .
