> studying years to be a doctor [...] Should you just start cutting people
Spoken like someone who’s never used AWS or been a doctor. Your analogy is horribly, badly flawed. Doctors do start cutting people, in the US nearly all med students dissect a cadaver at the start of their first year. What you’re suggesting is doing years of pure documentation reading, unguided by other people or a curriculum, before practicing AWS, which would be silly and a waste of time. People learn by practicing, which is why med students dissect cadavers, and which is why AWS offers a “free” platform to learn by practicing, tutorials to guide the learner, and advertising to attract learners.
> If money is a concern
Maybe this is why AWS offers a “Free Tier”? https://aws.amazon.com/free/
> AWS is not for developers
That’s not what AWS says https://aws.amazon.com/developer
