Caching, CDN, Queues & Asynchronous Processing Junior Beginner

Quick Interview Answer

Asynchronous processing moves work that does not need to finish within the original request into a separate execution path. The request can acknowledge or record the work while a background processor performs it later.

Detailed Explanation

Typical examples include sending email, generating reports, image processing, and integration tasks. The system must define durability, retries, failure handling, status tracking, and idempotency for important jobs.

Code Example

HTTP Request
    |
Create job/message
