    as in the server chats with another

    Centralized servers in which 2 users talk can be considered “synchronous” because they get the message nearly instantly, but yea, we often use NoSQL async calls for instant messaging apps

      Oh on a technical level yes. But on the surface it’s still asynchronous, as long as you can’t tell whether the other person has read your message (which, to be fair, a lot of messaging applications have as a feature)
