End-to-End Event Streaming With Kafka, Spring Boot and AWS SQS/SNS (Production-Ready Code Guide)

Source: DZone DevOps

Event‑driven applications often demand high throughput, reliable delivery, and flexible fan‑out messaging. Each platform in our stack plays a distinct role:

• Apache Kafka – a distributed, high‑volume event log.
• Amazon SQS – durable point‑to‑point queues.
• Amazon SNS – pub/sub broadcasting to multiple subscribers.

Using them together yields a robust pipeline. Teams commonly use Kafka for streaming, SQS for decoupled processing, and SNS for multicasting events. This synergy leverages the strengths of each platform to build scalable, loosely coupled systems.

Architecture Overview

The pipeline involves multiple components working together in sequence. Below is the event flow:
