It's a cryptographic protocol designed to secure the connection between the web server (where the website is hosted - in this case on Amazon's AWS Cloud) and the browser (which your visitor uses to access said website).

In short, it prevents bad actors from snooping on the connection - something which is important for privacy and security, but also user trust and SEO. It's also responsible for the padlock icon you'll see in your address bar.

The major benefit of TLS 1.3 over 1.2 is the increase in connection speed. TLS 1.3 removes an extra round trip communication between the browser and the server, helping websites to load more quickly, especially on high-latency mobile or satellite connections.
