Bullshit. Leads come off, equipment malfunctions, patients fidget, and they definitely don't have redundant stuff on each patient.

I'm going to guess grandparent means that they don't include "downtime" in the contract. Which would be outrageous, BTW.

He's saying that any computer system hosting the data would have downtime. Your own custom data center can blow up just as easily as Amazon's.

Now, if zero downtime is the requirement, then you just need to have a lot of data centers and well-tested failover procedures. It's all very simple, and EC2 can easily be one of those redundant data centers.

Do not believe.
