I'm actually curious how AWS is able to scale support so well with what seems reasonable quality. I had an issue (my fault in end), got excellent support - and they didn't tell us to take a hike at end when it turned out not AWS fault.
Conversely, with GCP 4 years ago now had some support issues - didn't come away impressed - I'm convinced even internally GCP isn't well doc'd or something.
I think it comes down to Amazon vs. Google's company cultures around customer support, which informs attention and resource budgeting. GCP isn't the only Google product where people hate its customer support, and AWS isn't the only Amazon product where people love its customer support.
Amazon takes the customer support very far - with one exception - bogus products on marketplace seems like a big miss.
But what I paid for and got on aws support is so far out of whack there is NO way they made money on my account for that whole year. And the person was actually competant which was a shock. So many "technical support" folks seem like idiots.
Comcast for example, I'd purchased my modem, they started charging a rental fee - I had to call these bozos every month to reverse the charge - a total waste of time. I cancelled finally - I just couldn't take it, and each one lied to me or didn't have a clue. Things like condescendingly saying - you have to pay for the modem.
