Planning your network is something everyone has to do whether or not they are using AWS. I think its unreasonable to expect to just throw stuff in AWS without thinking about it and then complain when something comes up unexpectedly.
The issue is that lots of folks get started on AWS (or any cloud provider) and because everything’s built around getting developers in a hurry to push out some code this step is increasingly taking less and less time. Sure, it’s not a big deal for the usual start-up that fizzles in a couple years but once it’s going and there’s actual users the system is setup that there will be a forced outage of some sort when a couple hours investment would have prevented a lot of headaches.
The common pivot for a company is to go from a b2c company to b2b and that means regulations. That means you can’t do cowboy infrastructure setup like people setup their home network (in fact, most home networks are more secure than what most SaaS devs do as a rule sans router firmware exploits).
