That’s a fair point, but I would look to specific markets instead of tech to see where AWS and Amazon might run into issues.

Specifically within healthcare. You think large Pharma companies will use AWS after the pill pocket acquisition? Do you think once Amazon.com starts listing prosthetics large life sciences companies will run on AWS? What about providers? Do you think health systems will choose AWS as their cloud once Amazon launches their version of KP?

I don’t see Azure or GCP getting into these specific markets.

I would agree that it's unlikely that Google or Microsoft will start making prosthetics -- although they could spin GCP or Azure off into other corporate entities or operators who did someday.

More likely would be that Google, Amazon, Microsoft and some affiliated company would be competing in a space where telemetry from something like a prosthetic was reporting information that had some value.

In any situation, the downside of renting something is that you lose control. It is something that you need to think about and incorporate into your business strategy in some scenarios.

Do you see Netflix hosting their entire infrastructure on AWS after Amazon released Amazon Video.....
