🧵 05. Amazon MQ
Amazon MQ is a managed message broker service for Apache ActiveMQ (and RabbitMQ).
It provides open-standard protocols for messaging — ideal when migrating traditional applications to AWS.
🧩 Concept Overview
While SQS and SNS are cloud-native, fully managed AWS messaging services,
some legacy or enterprise systems use open messaging protocols such as:
- MQTT
- AMQP
- STOMP
- OpenWire
- WSS
Instead of rewriting these applications to use AWS-specific APIs (SQS/SNS),
you can migrate them to AWS using Amazon MQ with minimal code change.
⚙️ How It Works
| Component | Description |
|---|---|
| Broker | Managed Apache ActiveMQ or RabbitMQ instance running inside AWS. |
| Producers & Consumers | Use standard protocols (AMQP, MQTT, etc.) to send and receive messages. |
| Queues & Topics | Supports both models — queues (like SQS) and topics (like SNS). |
✅ Great for lift-and-shift migrations.
✅ No need to refactor existing apps that already use messaging.
❌ Not serverless — runs on a dedicated EC2-like broker instance.
