RabbitMQ

RabbitMQ is a reliable and mature messaging and streaming broker, which is easy to deploy on cloud environments, on-premises, and on your local machine. It is currently used by millions worldwide.

📦 What is RabbitMQ?

RabbitMQ is a message broker — a software that enables applications, systems, and services to communicate with each other and exchange information via messages, without being directly connected.

It implements the Advanced Message Queuing Protocol (AMQP) and acts like a post office:

• Producers send messages.

• Consumers receive them.

• RabbitMQ handles the routing, queuing, and delivery.

💡 Why Use RabbitMQ?

• 🔁 Asynchronous Communication
  Tasks can be processed in the background — perfect for sending emails, processing uploads, etc.

• 🧱 Decoupling
  Microservices don’t need to know about each other directly — they only communicate via queues.

• 📈 Scalability
  Add more workers or queues to handle higher loads.

• 🛡️ Reliability
  Supports message durability, acknowledgments, and retries to prevent data loss.

Basic Flow
Producer ---> Exchange ---> Queue ---> Consumer
