Iris: A decentralized approach to backend messaging middlewares
In this work we introduce the design and internal workings of the Iris
decentralized messaging framework. Iris takes a midway approach between the
two prevalent messaging middleware models: the centralized one represented by
the AMQP family and the socket queuing one represented by ZeroMQ; by turning
towards peer-to-peer overlays as the internal transport for message
distribution and delivery. A novel concept is introduced, whereby a
distributed service is composed not of individual application instances, but
rather clusters of instances responsible for the same sub-service. Supporting
this new model, a collection of higher level messaging patterns have been
identified and successfully implemented: broadcast, request/reply,
publish/subscribe and tunnel. This conceptual model and supporting primitives
allow a much simpler way to specify, design and implement distributed, cloud
based services. Furthermore, the proposed system achieves a significant
switching speed, which - given its decentralized nature - can be scaled
better than existing messaging frameworks, whilst incurring zero
configuration costs.</jats:p
