What is a message bus architecture and how might one be used?

Structure the connecting middleware between these applications as a Message Bus that enables them to work together using messaging. A Message Bus is a combination of a common data model, a common command set, and a messaging infrastructure to allow different systems to communicate through a shared set of interfaces.Click to see full answer. In this regard, what is a message broker used for?The primary purpose of a broker is to take incoming messages from applications and perform some action on them. For example, a message broker may be used to manage a workload queue or message queue for multiple receivers, providing reliable storage, guaranteed message delivery and perhaps transaction management.Secondly, why ESB is used? When to Use Enterprise Service Bus (ESB) ESB, a middleware technology, is a Bus-like architecture used to integrate heterogeneous systems. In ESB, each application is independent and yet able to communicate with other systems. It, thus, prevents scalability issues and ensures that communication happens only through it. Furthermore, what does a service bus do? An enterprise service bus (ESB) is a middleware tool used to distribute work among connected components of an application. ESBs are designed to provide a uniform means of moving work, offering applications the ability to connect to the bus and subscribe to messages based on simple structural and business policy rules.What is ESB middleware?An enterprise service bus (ESB) implements a communication system between mutually interacting software applications in a service-oriented architecture (SOA).
