Earlier quoted context omitted.
Why can’t they just backup regularly and redeploy somewhere? Isn’t it as easy as backing up a DB and restoring?
If you restrict yourself to only the set of AWS functionality that is common to all hosting providers, you can do that. But not only is that very hard to do, it basically negates the premise of AWS in general. There are also lots of areas that you can’t do this, such as IAM and network rules, so you have to build an abstraction on top of it that’ll work with open source tools on a separate host.
The rest of it? I think I understand why some systems need/want it, but no thanks.
