Enterprise Bus

Enterprise Bus: Software Architecture Model

An enterprise bus is a software architecture model for distributing data across applications, databases and message brokers in a large enterprise IT environment. It allows different applications to communicate through a common messaging backbone that routes messages between applications using common standards.

What is Enterprise Bus?

An enterprise bus (ESB) is a software architecture model that enables integration of systems and data across an enterprise. It is a messaging backbone that sits between all applications, databases and systems and handles routing of messages between them using common standards and protocols.

Some key capabilities of an enterprise bus include:

• Serves as a central hub for communication between applications
• Enables integration between different systems through common standards like APIs or messaging
• Provides message transformation so that data in different formats can be translated
• Performs message routing between applications and systems
• Manages transactions, security, scalability and availability

An ESB aims to implement a reusable architecture for integration that reduces the direct dependencies between systems. This means that instead of each system connecting directly to every other system it needs to integrate with, they only connect to the bus. This reduces the number and complexity of connections.

Major benefits of using an enterprise bus architecture include increased agility in adding new systems or changing existing ones, easier application integration and reduced systems maintenance costs over time. Leading enterprise bus software platforms include TIBCO BusinessWorks, Oracle Service Bus and Microsoft BizTalk Server.
