Many startups and companies couldn't exist if there was only AWS (or GCP / Azure) due to how much they overcharge.
For example, we couldn't offer free GeoIP downloads[0] if we were charged the outrageous $0.09 / GB, and the same is true for companies serving AI models or game assets.
But what makes me almost sick is how slow is the cloud. From network-attached disks to overcrowded CPUs, everything is so slooooow.
My experience is that the cloud is a good thing between 0-10,000 $ / month. But you should seriously consider renting bare-metal servers or owning your own after that. You can "over-provision" as much as you want when you get 10-20x (real numbers) the performance for 25% of the price.
I’ve seen cloud slowness create weird Stockholm syndrome effects, especially around disk latency.
It always makes sense to compare to back of the envelope bare metal numbers before rearchitecting your stack to work around some dumb cloud performance issue.
