OpenStack Message Bus ("Marconi")
Marconi is a new OpenStack project to create a multi-tenant, light-weight, fast, scale-out alternative to other popular queuing systems. The service will support 100's of thousands (or even millions) of clients and channels in a cost-effective manner, without sacrificing performance, durability, or HA.
This project's objective is not to supplant intra-cluster message buses, such as those based on AMQP and DDS. Rather, Marconi provides a complementary service that is optimized for extra-cluster messaging between many thousands of Internet-connected agents.
Marconi will define a clean, RESTful API, use a modular architecture, and will support both eventing and job-queuing semantics. Users will be able to customize Marconi to achieve a wide range of performance, durability, availability, and efficiency goals.
