The time-critical parts of a hospital's workflow are less IT-dependent than the time-critical parts of an airline's workflow. You need a computer to handle admissions in hospitals, but you can get by with the actual medicine with the computers offline (there's a LOT of paper replication).
Besides, if $CLOUD_PROVIDER has a couple of hours outage and the patient records aren't available, not that much backs up. There's not that much in the count of patients that's affected by, say, a 2-hour outage. But that same length of outage can affect thousands of passengers across a dozen airports, and cause knock-on effects for days.
- Johnny555 10y agoI wasn't comparing uptime needs of a hospital versus an airline, but their security needs. Every major cloud provide offers multiple independent regions, and I haven't heard of any suffering from a multi-region outage. If an airline's application can't tolerate an outage, then they better not host it in a single region, whether they host it themselves or host it in the cloud. Delta is on day 2 of their outage, Southwest's was 12+ hours. Google had a major outage in April -- it lasted 18 minutes. In June, AWS lost a single Availability Zone (out of 3) in Sydney for about 12 hours.
