RabbitMQ

RabbitMQ is an open-source message broker software that facilitates communication between different applications through a messaging protocol. It was originally developed by Rabbit Technologies Ltd, which later became part of Pivotal Software and is now maintained by the open-source community. Introduced in 2007, RabbitMQ supports multiple messaging protocols, including Advanced Message Queuing Protocol (AMQP), making it a versatile choice for various real-time messaging solutions.

RabbitMQ uses the AMQP protocol to enable robust and reliable inter-process communication. This makes it an ideal choice for applications requiring high-throughput, real-time data processing, and guaranteed message delivery. The software is widely used in microservices architectures, IoT (Internet of Things) solutions, and financial systems. RabbitMQ's architecture consists of producers, consumers, and queues, where messages are queued up until they can be processed by consumers. Besides AMQP, RabbitMQ supports other protocols like STOMP, MQTT, and HTTP, making it highly adaptable. The software offers features such as message acknowledgments, delivery retries, and clustering for high availability, ensuring it meets the demanding needs of modern distributed systems.
