AWS is built for production. It’s complex because it’s designed to create robust environments that can scale almost infinitely, that’s why half of the internet runs on AWS. But to make the most of it, you need to understand how it works and why it’s built that way. That’s why being an “AWS expert” is practically a job description on its own, thats why cloud engineering teams exists, platforms, SRE, etc.
For quick and dirty app deployments, though, other vendors like Heroku probably do a better job.
