RabbitMQ	RabbitMQ is an AMQP (Advanced Messaging Queuing Protocol) message broker. It supports multiple messaging protocols, message queuing, delivery acknow led gement, flexible routing to queues and multiple exchange types RabbitMQ can be deployed with Docker, Puppet, Chef and BOSH RabbitMQ can be deployed as clusters for high availa bility and can be federated across multiple availa bility zones and regions
Protocol Support	AMQP - It is a default implementation in RabbitMQ MQTT - Used for light scenarios. Binary exchange. STOMP - Text-based data exchange HTTP - Our very popular internet protocol While Kafka supports Binary protocol over TCP.
Key Terms	Producer - a programm that sends messages. Consumer - a programm that reads messages. Publishers Exchange - takes a message from producers and routes it into zero or more queues. Routes Queue - a buffer that stores messages. Topics Subscribers Bindings - rules that exchanges use to route messages to queues.
Exchange types	default - exchange with no name pre-declared by the broker. Every queue that is created is automatically bound to it with a routing key which is the same as the queue name. direct - delivers messages to queues based on the message routing key. It?s ideal for the unicast routing of messages. It?s often used to distribute tasks between multiple workers. topic - routes messages to one or many queues based on matching between a message routing key and the pattern that was used to bind a queue to an exchange. The limitation for routing key is 255 bytes. fanout - routes messages to all of the queues that are bound to it and the routing key is ignored headers- routes multiple attributes that are more easily expressed as message headers than a routing key. routing key is ignored.
