2. AMQP – Advanced Message Queuing Protocol  A open standard application layer protocol for message oriented middleware  The defining features of AMQP are message orientation, queuing, routing, reliability and security  Ii is a wire level protocol
3. Features  Scalable & Reliable  Persistence delivery ACKs  Plugin Extension  Management, STOMP, MQTT, Tracing  Management UI [ Port : 15672 ]  Multiple protocols supported  Tracing  [ Firehose Tracer : rabbitmqctl trace_on]
4. Features(Contd.)  Clustering Many nodes form a Single Logical Broker  Flexible routing Exchange  Highly Available Queue Queue Mirroring
5. Features(Contd.)  Metering  Rate limiting (baseline and SLA based)  Specifies maximum value for the number of messages processed per time period and rejects any messages beyond the maximum  Throttling  Throttles the number of messages per time period processed by an API. Queues any messages beyond the maximum for later processing
6. Core Features Publish-Subscribe Reliability Scalability
