The ESB stands for enterprise service bus and is concentrated on applying a centralised software component to attach applications that perform an extensive range of services. Being a part of a service-oriented architecture, the ESB establishes data connections between applications.
With such a “bus-like” infrastructure, it’s possible to distribute tasks like message routing and decoupling among multiple connected elements that make up an application. Applications don’t interact directly but transfer data through the “bus”.
In this way, engineers don’t need to create custom-built integrations for each app. It speeds up the development process and enhances business agility.
