Message Queues and Asynchronous Integration
Enterprise iOS apps rarely talk to backends synchronously. This lesson covers integrating Objective-C clients with message queues and event-driven systems for resilient, decoupled communication.
Why Asynchronous Integration
Enterprise systems decouple producers from consumers using message queues. The iOS client sends a message and continues, rather than blocking on a response.
- Survives temporary backend downtime
- Smooths traffic spikes
- Enables event-driven workflows
Queues vs Request/Response
A direct request/response call fails if the server is down. A queued message waits until a worker processes it. The trade-off is eventual consistency instead of immediate results.
