Pros : -

• It can be configured to use SSL thereby providing additional layer of security.
• It has a versatile interface when compared to Redis as a message broker.
• Offers clustering and is very good at it.
• Scales to around 500,000+ messages a second.

Cons:-

• Needs Erlang.
• Minimal configuration that can be done through code. (Configuring RabbitMQ is something that must be done first before even implementing your task queue.)
