I'd counter that past a certain scale, certainly the scale of a firm that used to & could run its own datacenter.. it's probably your responsibility to not use those services.

Sure it's easier, but if you decide feature X requires AWS service Y that has no GCP/Azure/ORCL equivalent.. it seems unwise.

Just from a business perspective, you are making yourself hostage to a vendor on pricing.

If you're some startup trying to find traction, or a small shop with an IT department of 5.. then by all means, use whatever cloud and get locked in for now.

But if you are a big bank, car maker, whatever.. it seems grossly irresponsible.

On the east coast we are already approaching an entire business day being down today. Gonna need a decade without an outage to get all those 9s back. And not to be catastrophic but.. what if AWS had an outage like this that lasted.. 3 days? A week?

The fact that the industry collectively shrugs our shoulders and allows increasing amounts of our tech stacks to be single-vendor hostage is crazy.
