I know Elastic Beanstalk and Lightsail both exist; but they’re both much more complicated than `git push heroku master`. And that’s not even counting what you have to do/learn to be able to wire up a DB or Redis instance or Email deliverability on AWS.
Straightforward to you may still be magic to most non-tech people. They will pay an insane premium to not have to worry about this type of stuff.
And to do the setup of a bare metal web service was not much more to know.
This is especially true looking at prebaked stuff like what digital ocean offers. You can use their Django image and the entire thing is ready to go.
Ultimately, docker and docker orchestrations are fairly standard devops skills at this point.
I think these paas solutions take devs who might otherwise bite the bullet and learn how to work with these in the wrong direction.
