It's a lot more complicated than anything reasonable about deploying a webapp. Any shared hosting solution or deployment platform (think fly/shuttle) will be cheaper and easier to reason about. Even selfhosting on a rented VM or dedicated server and configuring auto-updates and maintenance windows will be much easier.
By going to netlify/AWS you are now tying the destiny of your app to two megacorps, doubling the risk of downtime (and cloud uptime is certainly not as good as dedicated) and other bugs.
