As everyone has explained MSMQ is used as a queue for messages. Messages can be wrapper for actual data, object and anything that you can serialize and send across the wire. MSMQ has it's own limitations. MSMQ 1.0 and MSMQ 2.0 had a 4MB message limit. This restriction was lifted off with MSMQ 3.0.
How it Works. RabbitMQ MQTT plugin targets MQTT 3.1.1 and supports a broad range of MQTT clients. It also makes it possible for MQTT clients to interoperate with AMQP 0-9-1, AMQP 1.0, and STOMP clients.There is also support for multi-tenancy. The plugin builds on top of RabbitMQ core protocol's entities: exchanges and queues.Messages published to MQTT topics use a topic exchange (amq.topic by default) internally.Subscribers consume from RabbitMQ queues bound to the topic exchange. This both enables interoperability with other protocols and makes it possible to use the Management plugin to inspect queue sizes, message rates, and so on.ow it Works.
