Only if that system is stateless. If you have any sort of internal memory that sticks around between requests, then either you face a cold start problem (because of empty caches) or you somehow need to persist that state somewhere. And persisting that state either means you need a backup solution or your latency is terrible because you are hitting network for something that only needs to hit RAM.
