You can always set a super short TTL like 15s or even 1s. It's still going to make scaling a non-issue like that and at some point the caching will be fresher

You can always set a super short TTL like 15s or even 1s. It's still going to make scaling a non-issue like that and at some point the caching will be fresher then the html generation, as that needs to be done too (and read after by the http server). It's fun to make architecture like in the article though, I'm guilty of it as well with previous hobby projects
