Return on Intelligence

This document provides an overview of composite SOA frameworks, including Enterprise Service Bus (ESB) structures and technologies. It discusses service mapping and routing using UDDI, and component containers like SCA, JBI, and OSGi. Key capabilities of ESBs are described such as routing, transformation, orchestration. Implementation technologies include ActiveMQ, JBossMQ, Oracle AQ, and MQ Series. The roles of UDDI, JBI specifications, OSGi, and SCA are summarized. The document concludes with a list of projects and technologies that support JBI, SCA, and OSGi.

Exigen Services confidential Routing: UDDI
Exigen Services confidential UDDI – service routing Client wants to call service 1 (client doesn’t know service1 endpoint ) 1. All services are registered in UDDI 2. Client call UDDI “I need service1, where is it?” 3. UDDI search that service in repository and return service1 endpoint 4. Client call service1 on endpoint was got from UDDI 2 3 4 1
Exigen Services confidential UDDI summary Benefits:  Simplify business-to-business (B2B) interaction  Separate service from description  Allow hot switch to other service location  Providing Application Visibility at Design Time Universal Description, Discovery and Integration  UDDI provides a standards-based set of specifications for service description and discovery. Extensible Markup Language (XML) which used for WSDL for describe services  UDDI supports a highly flexible description of services with metainformation (Service Layer Agreement)  WS-SecurityPolicy

Exigen Services confidential Component containers: JBI
Exigen Services confidential JBI (JSR-208) Java Business Integration (JBI) specification (Oracle)  The goal of JBI is to create a standards-based architecture for integrating middleware components to perform ESB capabilities  The JBI Specs is not concerned about how external consumers or service providers interact, but rather how internal consumers and providers interact  JBI dependent on J2SE but not J2EE  JBI defines two types of components - Service Engines (process choreography, transactions, security, message transformation, protocol transformation) - Binding components ( XML, HTTP, MQ, IIOP) 15
Exigen Services confidential JBI 16 jbi.xml - installation descriptor define a unique component name and type along with the classpath settings that are required during installation and runtime of the component. Life Cycle

Exigen Services confidential JBI Specification architecture 18 Standard Can be open source WSDL WSDL Java / Swing Java / EJB Servlet
Exigen Services confidential JBI summary JBI advantages and the effect on commercial ESBs  Third party Custom Service Engines (SE) and Binding Components (BC) can be swapped in and out without impacting applications or services  Avoids “Vendor lock-in”  We can swap in and out integration services (i.e. capabilities) we don’t need, creating a lighter-weight solution that meets our specific needs 19
