Extended Services are composite applications created as event-driven assemblies of micro services (also known as Business Components) linked to each other by Data Routes. The components can be made to run on a single JVM with server group acting as runtime containers for processing micro-services while peer server can dedicate itself managing the routes and destinations, and communicating metadata with micro-services. These Extended Services can be launched on multiple peer servers with the components launched on each peer server present in the specified server group.
The Extended Services are designed by drag-drop-connect function of micro-services. The components are customized by configuration rather than by custom code. The routes between components are drawn by visually connecting the component ports. Every component instance in the flow can be configured so that it can be deployed on different ESB network nodes.
