An Enterprise Service Bus (ESB) in manufacturing is a middleware architecture that enables different industrial applications, systems, and devices to communicate seamlessly. It acts as a central hub that standardizes data exchange between ERP, MES, SCADA, and other enterprise applications.

ESB improves flexibility by allowing manufacturers to integrate new technologies without disrupting existing operations. It supports real-time data flow, process automation, and interoperability, making it an essential component of digital transformation strategies.

With the growing complexity of industrial environments, ESBs play a crucial role in streamlining operations and improving data consistency across IT and OT systems. They help manufacturers transition to a connected, data-driven ecosystem.
