This post doesn't live up to its title, I'm sorry about that.
The title should have been 'We are building a better Heroku FOR PRODUCTION APPS' (we'll add the 'for production apps' to the title)
It should have emphasized the _building_ part, we're just starting. The current 5 minute production app doesn't hold a candle to Heroku at the moment.
It should have made it clear the goals is to improve the speed with which you can configure a production app, not a development app. Development apps on Heroku are already close to perfect. The examples in this post are contrived since it talks about a development app, as rightly called out by Heroku people https://twitter.com/johnbeynon/status/1374306499426652161
It should have gone into why hyper clouds might be preferable https://gitlab.com/gitlab-org/5-minute-production-app/deploy...
It should have talked about state, we made a small improvement in https://gitlab.com/gitlab-com/www-gitlab-com/-/merge_request... but we should have done the planned work in https://gitlab.com/gitlab-com/www-gitlab-com/-/issues/11137 and made one post out of it.
