ykaplan - Marconi - OpenStack Queuing and Notification Service Marconi is a multi-tenant cloud queuing system written in Python as part of the OpenStack project. Marconi aims to ease the design of distributed systems and allow for asynchronous work distribution without creating yet another message broker. This talk aims to give the audience a broad look at Marconi’s design and technologies used. ----- Similar to other message bus frameworks, Marconi's main goals are: performance, availability, durability, fault-tolerance and scalability. Besides providing support for queuing and notification services through OpenStack, Marconi aims to ease the design of distributed systems and allow for asynchronous work distribution without creating yet another message broker. This talk aims to give the audience a broad look at Marconi’s architecture, design, technologies used, development process, and discuss the issues it adresses.
