...This pattern lets services running in distributed environments take advantage of NATS’ low latency and flexible topology while retaining familiar client semantics. It can be an effective bridge for teams migrating from synchronous REST calls to a message-driven fabric without rewriting every call site. Because the transport is swappable, it promotes clean separation between business logic and the underlying network. The result is an incremental pathway to evented architectures with the ergonomics of conventional request/response programming.
