Project Tango Brings Quality of Service to Web Services

Posted by ryan_shoemaker on April 16, 2006 at 2:01 PM PDT

Project Tango is a Sun initiative focused on delivering interoperable Web services technologies. Web Services Interoperability Technology (WSIT) is an open-source implementation of next generation Web services technologies that deliver interoperability between Java EE and .Net to help you build, deploy, and maintain Composite Applications for your Service Oriented Architecture. It is focused on four main categories: Messaging, Metadata, Security, and Quality-of-Service (QoS).

Part of the QoS offering in Project Tango is support for WS-Coordination which provides a mechanism to join and participate in distributed operations that require consistent agreement in either tightly (WS-AtomicTransactions) or loosely (WS-BusinessActivity) coupled operations. WS-Coordintation allows web services to bridge into heterogeneous transactional environments and provides a layer of QoS beyond traditional 1st generation web services.

If you will be attending JavaOne this year, please come see technical session TS-1603 "Reliable and Transacted Web Services between Project Tango and Microsoft Indigo" to learn more about the QoS functionality being introduced as part of project Tango.
