XMPP/AMQP/Websockets vs Pusher/Beacon push?

With Pusher and Beacon push cloud services I can get live开发者_如何学编程 updates in all browsers. Even implement chat functionality.

Can't these cloud services replace the need of me learning XMPP/AMQP/Websockets/Comet to implement the same kind of live updates/feeds?

These services offer Infrastructure as a Service so that you don't have to worry about the underlying technology. That said the services do use the technology as a selling point e.g. Pusher very much use WebSockets to sell their service.

As well as Pusher there are similar services so I'd recommend checking out the real-time tech guide for others that haven't been mentioned (I work for Pusher).

Yes. The point in these frameworks and services is to abstract away the underlying connection and protocols to provide you with a reasonable real-time communication pattern (simple messaging, pub-sub, evented pub-sub, RPC/RMI or DataSync) that works for the application functionality that you are looking to build.
