You forgot the part where the provider of your serverless charges you a multiple of what your idling server would cost you.
It’s basically slicing up a server and selling you some slices at an exaggerated premium.
You spend more on supervising the stuff running on the slices so they don’t bankrupt you when a peak happens than you would for maintaining a server.
But hey, it’s fashionable to be serverless so let’s all do it
In general I like the approach to make such a futuristic looking thing with sharp angles etc. „like from a sci-fi movie“. The problem is the thing only looks cool in marketing brochures with the right lighting and photoshopping.
In real life the thing looks goofy AF, like a joke. Like it’s ordered from TEMU.
It’s immediately obvious that it’s just a janky, non-solid tin cover over a normal car body.
