Your comment is unproductive and unnecessarily sarcastic. It would seem obvious the parent has used the services provided by AWS, and your focusing entirely on the perceived negatives and friction when combining services is not constructive.

Are you suggesting there is less friction in using multiple softwares, likely as self hosted, produced by separate developers, compared to using services hosted by AWS which allow you to only worry about building your product and managing links between services? The latter almost undeniably leads to greater productivity over the former, and if you're interested more about building and delivering a software product, that must be preferable.
