Fairly simple question, People who've worked with requirements where real time updates are really necessary. It could be a chat app, event based architecture that needs constant updates or maybe activity based stuff like how Stripe has the whole webhooks.
The general solution I see everywhere is a combination of a message broker and web socket, message broker takes care of handling the event messages on the server and web socket takes care of letting the client app know that it needs to request for updates.
What other solutions do you think should be considered and which you think are better?
