As a software architect, I hate serverless. Not because it doesn't work, but because it forces design constraints that cripple your application. Here's why always-on servers matter.
A poor architect blames their tools. Serverless is an option among many, and it’s good for occasional atomic workloads. And, like many hot new things, it’s built with huge customers in mind and sold to everyone else who wants to be the next huge customer. It’s the architect’s job to determine whether functions are fit for their purposes. Also,
Here’s the fundamental problem with serverless: it forces you into a request-response model that most real applications outgrew years ago.
IDK what they consider a “real” application but plenty of software still operates this way and it works just fine. If you need a lot of background work, or low latency responses, or scheduled tasks or whatever then use something else that suits your needs, it doesn’t all have to be functions all the time.
And if you have a higher-up that got stars in their eyes and mandated a switch to serverless, you have my pity. But if you run a dairy and you switch from cows to horses, don’t blame the horses when you can’t get milk.
