Since I began posting on Medium and DEV Community, I have learned that it's a good idea to let search engines know they are the same content on different URLs. I have also just realised that you could let people read what you wrote on Medium without the paywall, and am a little surprised that HTTP/2 is not enabled by default on AWS CloudFront.
HTML: having a canonical link (
<link rel="canonnical" href="https://example.com" />) in your HTML helps prevent content duplication in search engines, good for SEO.SEO: to add a canonical link on DEV Community, use the front matter
canonical_url. As for Medium - on your post, open up Story settings > Advanced Settings > check "This story was originally published elsewhere" and provide a canonical link.Medium: Friend Link grants free access to your post, find it on your post > Story settings > Promotion > Friend Link.
AWS CloudFront: distributions don't support HTTP/2 by default. Check the settings manually, or on CloudFormation, add
HttpVersion: http2toDistributionConfig.Latency: Hibernia Express / GTT Express is a submarine fibre-optic link that provides latency of under 60 milliseconds, which costed hundreds of millions to complete. Latency can be really expensive.
