Google Cloud Platform has MASSIVE markups compared to equivalent service providers, either from "the big three" or smaller service operators. These smaller service operators have far less margin to work with, yet manage to not only break even but to turn a profit! Either GCP has some product that is a metaphorical black hole consuming all of their excess revenue, or Google generally is spending far too much money doing the same thing that everyone else is doing.
One of the things I've noticed GCP prides themselves on is uptime, and I'm wondering whether they're doing something like _doubling_ their costs to have seven nines of uptime for the entire platform, which practically doesn't matter for anyone other than a handful of clients (healthcare, government, military, etc)
