I’ve worked on a product where half the backend (basically, the control plane but not the data plane) was completely serverless: lambda, DDB, step functions, api gateway

I think it was generally convenient as being very low maintenance. The only availability canary alarms are when the underlying services go down, which is almost never.

Debugging and running locally are the weak points. Eliminating an entire class of things to think about (container health, scale in and out, and so on) is very nice. Since it’s a control plane, tps and costs were low.
