I don't expect the majority of tech companies to want to run their own physical data centers. I do expect them to shift to more bare-metal offerings.
If I'm a mid to large size company built on DynamoDB, I'd be questioning if it's really worth the risk given this 12+ hour outage.
I'd rather build upon open source tooling on bare metal instances and control my own destiny, than hope that Amazon doesn't break things as they scale to serve a database to host the entire internet.
For big companies, it's probably a cost savings too.
