Saving $426/mo for a business seems like a waste of time and resources. The excessive frugal developer complex. How many hours did it take to do the migration?
The hours they put into not wasting money on AWS today could pay off many times if it makes their SaaS economically viable for their target audience.
How come? The baseline for that comparison will also stay static, regardless of how many TPS or whatever is going on, meanwhile the AWS price they're comparing to would only increase the more people use whatever they deploy.
