What is "proper platform knowledge"? Certifications are generally far inferior to hiring actual good engineers, which in my experience Google does. Comparing AWS to Google, our Google support is way higher touch and they give us way more experienced people (actual engineers). Most enterprises don't have a clue about computing though, so I can buy that they would prefer bling like certificates to getting a contact who is a real engineer.
