Editor's Notes
- Slide Objectives:Explain main differences between Relay and BrokerSpeaking Points:Main difference between Relay messaging and Broker messagingRelay messaging goes through direct, TPC-like connectionBroker manipulate messages (such as stamping) while relay is pass-throughBroker has storage, allowing loose-coupling between the sender and the receiver
- Platform dependency – code multiple interfaces in the backendScale – PNS handle needs to be refreshed when app is launched; Most PNSs don’t support multicastingRouting – not able to filter messages by custom criteria unless keeping track of each app
