Apache Pulsar vs RabbitMQ Both RabbitMQ and Pulsar can handle high-throughput message traffic and ensure reliable communication between various apps and other components of complex data systems.

However, there are important differences between them. Much of those differences stem from RabbitMQ's focus on simplicity and Apache Pulsar's support of more sophisticated messaging models. The drawback to Pulsar's modular architecture is the increased complexity. When running Pulsar, we must also install Pulsar Broker, BookKeeper, and ZooKeeper.

Another important, distinguishing difference is speed. RabbitMQ offers the fastest speed at the lowest throughputs, while Pulsar is significantly faster as throughput increases.
