Asynchronous Process

Intro

An Asynchronous Process sends a message and continues without waiting for a response. In EA, it improves resilience and scalability for decoupled systems.

Key points:

• Decouples producers and consumers in time
• Improves availability and throughput
• Common use cases: event‑driven integration, background jobs, messaging patterns, batch triggers
• Pitfall: complex error handling and eventual consistency

Examples:

• Order service publishes an event; fulfillment processes it later
• Email notifications queued and sent asynchronously
• Data sync triggered by events rather than request/response

In practice:

Relate patterns to Enterprise Architecture integration standards.

FAQs:

Q: Why choose async processing?
A: To improve resilience, scale, and decouple services.

Q: What’s the trade‑off?
Eventual consistency and more complex error handling.
