> The number of failures you can have on-prem is insane. Hardware can fail for all kinds of reasons (you must know this)
Cloud vendors are not immune from hardware failure. What do you think their underlying infrastructure runs on, some magical contraption made from Lego bricks, Swiss chocolate, and positive vibes?
It's the same hardware, prone to the same failures. You've just outsourced worrying about it.
The hardware is prone to the same failures, but the customers rarely experience them, because they handle it for you. EBS means never worrying about disks. S3 means never worrying about objects. EC2 ASG means never worrying about failed machines/VMs. Multi-AZ means never worrying about an entire datacenter going down.
Yes, you pay someone else to worry about it. That's kinda the whole idea.
