CloudAMQP is a service which provides managed RabbitMQ servers in the cloud. For developers, it offers a free plan, called “Little Lemur”. Clients can connect using various protocols: AMQP, AMQPS, HTTPS, STOMP and MQTT. Dedicated plans do also have support for WEB-STOMP.
The RabbitMQ STOMP plugin supports advanced queue features, which can be defined in the management interface but also from clients when the queue is created. No matter how these features have been declared, RabbitMQ requires that the client specifies the same feature settings anytime when this queue is used.
In this blog post of 2014, Jerry Kuch describes a performance study of RabbitMQ on Google Compute Engine. It demonstrated the ability to receive and deliver more than one million messages per second (a sustained combined ingress/egress of over two million messages per second).
At this high rate of combined ingress (1,345,531 messages per second) and egress (1,413,840 messages per second), RabbitMQ was keeping up with load and that only 2,343 messages are temporarily accumulated in its queues awaiting delivery.
