IBUS is a lightweight standard-based messaging system with enhanced features to provide flexible, reliable, and intelligent messaging.By relying on standards, the IBUS reduces the chances of vendor lock-in.
|
IBUS is a collection of web-services orchestrated using Business Process Execution Language (BPEL) to achieve the business requirements.
· BPEL is a common standard on how to publish multiple services orchestrate them into business processes and audit and manage the results.
· BPEL provides the ability to quickly adapt or create new business processes, both internally and to trading partner community (Extendibility).
· BPEL and Web services now provide a standardized integration interface and a standardized language for integration and process automation.
· Web service provides reusable services and solves the issues of interoperability between systems.

Platform
IBUS is implemented over GlassFish Enterprise Service Bus (ESB)which is a lightweight and agile ESB platform that packages the innovation happening with Project Open ESB, the GlassFish application server, and the NetBeans IDE into a commercially supported, enterprise-class platform. GlassFish ESB builds on over 18 years of Sun expertise within SOA, ESB, integration, and server-side Java platforms.
