It is perfectly sensible, easier even, to apply DDD concepts to small functional services. Define a bounded context and aggregates. Under the hood (inside the context) there are a number of strategies for handling side effects, data structures, and state transitions. I'm finding DDD + functional languages + serverless architectures work quite well together, so far.
