5. 5© 2005 Sonic Software Corporation ESB Role in Enterprise SOA Provide centralized service management and monitoring Connect services through enterprise-grade communications Mediate service interactions through metadata-driven configuration Host integration functions as intermediary services

6. 6© 2005 Sonic Software Corporation #1: ESB is just a new name for EAI. ESBs provide general-purpose SOA infrastructure that can be used for many applications, including EAI.

7. 7© 2005 Sonic Software Corporation #2: ESBs compete with J2EE application servers. ESBs complement app servers in an Enterprise SOA environment, by offering service mediation, intelligent routing, distributed communication and service management.

8. 8© 2005 Sonic Software Corporation #3: I don’t need an ESB if I’m using Web services. ESBs make it practical to deploy an Enterprise SOA through increased reliability, security and scalability in addition to post- deployment flexibility and service management.

9. 9© 2005 Sonic Software Corporation #4: An ESB is simply an abstract concept or design pattern. An ESB provides a specific set of capabilities, brought together in a coherent, unified service-oriented architecture.

10. 10© 2005 Sonic Software Corporation #5: ESBs are simply message- oriented middleware with a new marketing spin. In addition to their messaging layer, ESBs contain a full distributed services architecture, with the ability to host, configure, mediate, orchestrate and manage services.

11. 11© 2005 Sonic Software Corporation #6: ESBs will be obsolete once BPEL and the WS-* standards are complete. BPEL and the WS-* standards will further interoperability between ESBs and application platforms, but do not remove the need for service mediation, routing and management.

12. 12© 2005 Sonic Software Corporation #7: Microsoft is building an ESB with their “Indigo” project. Indigo will make it easier to build message-driven applications in.NET but doesn’t appear to include the configurable intermediaries, dynamic distributed deployment or management capabilities found in an ESB.

13. 13© 2005 Sonic Software Corporation #8: An ESB container can be implemented using an EJB container. ESBs require service containers that are lightweight, dynamically configurable and support event- driven services.

14. 14© 2005 Sonic Software Corporation #9: ESBs offer yet another proprietary middleware stack. ESBs are based on XML and Web services standards, and ESB vendors are implementing and contributing to the next generation of standards for further interoperability and openness.

15. 15© 2005 Sonic Software Corporation #10: ESBs are only useful for departmental applications. Hundreds of ESBs have been deployed around the world for mission-critical enterprise and B2B systems.
