An architectural pattern for integrating heterogeneous applications via a central mediation and transformation backbone.
An Enterprise Service Bus (ESB) is an architectural concept for integrating heterogeneous applications using a central communication backbone that mediates, transforms, and routes messages. It provides standardized connectivity, message transformation, protocol bridging, and governance to decouple services and centralize integration logic. It is commonly used in service-oriented enterprise landscapes.
