DevOps Dictionary

RabbitMQ is an open-source and highly extensible message queuing solution. It serves as a message broker that understands AMQP (Advanced Message Queuing Protocol) but can also work with other popular messaging solutions like MQTT. It is highly available, fault tolerant and scalable. It is built using Erlang OTP, a technology designed for creating stable, reliable, fault-tolerant and highly scalable systems. At a very high level, it is a middleware layer that enables communication between different services in your application, ensuring messages are not lost and supporting various quality of services (QoS) requirements.
