Everyone was locked out in a building am staying at (40 something stories) for several hours. When I asked the concierge if I can have a look at the system, it turns out they had none. The whole thing communicated with AWS for some subscription SaaS that provided them with a front-end to register/block cards. And every tap anywhere (elevators/doors/locks) in the building communicated back with this system hosted on AWS. Absolute nightmare.

Yes, but still probably a million times easier for both the building management and the software vendor to have a SaaS for that, than having to buy hardware to put somewhere in the building (with redundant power, cooling, etc.), and have someone deploy, install, manage, update, etc. all of that.
I wonder what happened to the building when us-east-1 went down.
