State-Of-The-Art of Messaging for Distributed Computing Systems

Abstract

Abstract:Modern software applications rarely live in isolation and nowadays it is common practice to rely on services or consume information provided by remote entities. In such a distributed architecture, integration is key. Messaging, for more than a decade, is the reference solution to tackle challenges of a distributed nature, such as network unreliability, strong-coupling of producers and consumers and the heterogeneity of applications. Thanks to a strong community and a common effort towards standards and consolidation, message brokers are today the transport layer building blocks in many projects and services, both within the physics community and outside.Moreover, in recent years, a new generation of messaging services has appeared, with a focus on low-latency and high-performance use cases, pushing the boundaries of messaging applications. This paper will present messaging solutions for distributed applications going through an overview of the main concepts, technologies and services.

A Flexible Distributed Simulation Environment for Cyber-Physical Systems Using ZeroMQ

“…In comparison, ZeroMQ is brokerless and does not need a central message server. The applications communicate directly with each other, so that messages can be transferred faster with fewer transmissions [16]- [18].…”
