If AWS shuts down tomorrow. There are a lot of companies that are going to be in the same boat - including Amazon and Netflix.

I would be more worried about my one colocated data center getting shut down or getting destroyed than the entire global AWS infrastructure that has data centers in 50+ availability zones.

As far as software, most AWS services are just managed versions of available software. Even if you're using lambdas for API endpoints, if you treat your lambdas like Controller actions, it shouldn't be that much of a heavy lift to concert them into standard MVC APIs equivalent.

For another perspective, listen to the podcast interview of Adrian Cockcroft, the guy who led the migration of Netflix's infrastructure from self hosted to AWS hosted.
