Messaging Service ("Marconi")

Marconi is a cloud messaging and notification service for developers building applications on top of OpenStack. The service features a web-friendly HTTP API, which developers can use to send messages between the various components of their SaaS and mobile applications, using a variety of communication patterns. Underlying the API is an efficient messaging engine designed with scalability and security in mind.

At first glance, Marconi's RESTful API may seem a bit out of the ordinary. Message brokers typically rely on a custom binary protocol and long-lived connections. However, many of today's developers prefer a more web-friendly HTTP API. They value the simplicity and transparency of the protocol, its firewall-friendly nature, and its huge ecosystem of tools, load balancers and proxies. In addition, cloud operators appreciate the scalability aspects of the REST architectural style.
