What are serverless systems if not (traditional) software systems then?

Serverless systems then are a highly decoupled, event-driven, distributed system, with small, highly independent pieces of software that rarely need to know about any other pieces of software.

So, the development process becomes about building a lot of small and decoupled elements, and testing them.

Learn and adjust before going serverless

The reason my title says what it says is simply to say that if you treat a serverless system as a software system, and try to build it that way, you are far more likely to struggle than you are to get the best outcome.
