I've had an idea for a potential free solution: www.wordpress.com
Nevermind. It's not an idea, it's a real product.
You're gonna have a very hard time if you want to run instances, lambda and dynamodb in the cloud only to run a blog with comments. First, it's really complex to setup, even for an experienced dev. Second, it's gonna costs a ton of money and you'll be at the mercy of your traffic.
This wasn't a solution for "a blog with comments" - it was a solution for a pluggable comments app that you could add to any site even static html. We were talking about Disqus so I was thinking about what Disqus brings to the table.

The whole point of the idea was that the setup would be templated. That's why I spelt out the steps I envisaged the end-user having to perform. Did you miss that part?

This depends on traffic and my hunch is that it would be quite affordable for most low/medium traffic blogs. Lambda is dirt cheap and Dynamo has a very generous free allowance. Also see the suggestion below and my reply. The comments section would only need to be generated when a comment was posted and the html fragment could be stored in a free CDN.
