Oracle Service Bus is a proven market-leading Enterprise Service Bus (ESB) built from the ground up for SOA life cycle management that provides foundation capabilities for service discovery and intermediation, rapid service provisioning and deployment and governance. This service-infrastructure software adheres to the SOA principles of building coarse-grained, loosely coupled and standards-based services, creating a "neutral container" in which business functions may connect service consumers and back-end business services, regardless of underlying infrastructure.

The core of SOA success depends on an Enterprise Service Bus (ESB) that supports dynamic synergy and alignment of business process interactions, continual evolution of existing services and rapid addition of new ones. To realize the benefits of SOA, it is imperative that IT organizations include a robust and intelligent service intermediary that provides a layer of abstraction to mask the complexities of service integration in heterogeneous IT environments, typical in today's enterprises. While an intermediary layer of abstraction previously implied a platform for customizing enterprise applications, today it implies toolkits for service customization and scalable infrastructures that support loosely coupled service interactions with a focus on service mediation.
