AMQP stands for Advanced Message Queuing Protocol. It is an open network protocol for exchanging messages between applications. It enables reliable and efficient message transmission between different systems and applications. AMQP is commonly used in distributed systems, cloud computing environments, and other applications where reliable and scalable message delivery is required.

An exchange is a message routing component that receives messages from producers and routes them to queues based on specific criteria. When a message is sent to an exchange, the exchange uses rules, known as bindings, to determine which queues should receive the message. The exchange then delivers the message to the appropriate queues based on the routing rules defined.

There are different types of exchanges in AMQP, such as direct, fanout, topic, and headers exchanges, each with its own routing behavior. Exchanges play a crucial role in the message routing process, allowing for flexible and dynamic message distribution within a messaging system.

Apache Kafka is an open-source distributed event streaming platform used by thousands of companies for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications.

see Concepts: Processing chain

A queue is a buffer that stores messages sent by producers until they are consumed by consumers. It acts as a temporary storage location for messages, allowing for asynchronous communication between different components of a system. Messages are placed in the queue by producers and then retrieved and processed by consumers. This queuing mechanism helps to decouple the sending and receiving of messages, enabling more flexible and efficient communication between applications.
