Ask HN: What AWS products would you use for a new web app?

Of course, until the app reaches a testable version, it'll be developed locally. But afterwards, I would like to use AWS products to reacth the market.

I started to read about various tools, but got overwhelmed with so many informations about various products.

Now, the question: if you would start a project with the above specs, what AWS products would you use? How would the perfect AWS stack look for you?

Thank you.
