That is why as a sole dev I no longer offer full-stack solutions: clients simply do not want to pay for the hours it takes to keep their back-ends monitored and secured. Yet, dynamic data is mostly inevitable in any modern web solution so I am increasingly relying on BAAS providers. My gamble is that it should be easier/cheaper for BAAS providers to maintain a team of knowledgeable and experienced engineers to tend infrastructure that runs several back-ends. It seems like a natural step from hey I trust you can run my hardware take my money to hey I trust you can manage my data take my money
