WSO2 has announced the availability of the open source WSO2 Enterprise Service Bus (ESB), version 1.7 to support enterprises' heterogeneous, high-volume service-oriented architecture (SOA) demands. The WSO2 ESB 1.7 offers new enhancements to stability and availability – resulting in scalability and error-free connections for high-volume SOA environments, even on standard hardware. Version 1.7 of the WSO2 ESB now integrates closely with the full-featured WSO2 Registry 1.1 for enterprise-class SOA governance.

The WSO2 ESB 1.7 is being introduced at the 13th Annual SOA World Conference & Expo 2008 East being held June 23-24 at the Roosevelt Hotel in New York, NY.

The WSO2 ESB 1.7 also adds support for the financial services sector through two standard protocols. The Financial Information eXchange (FIX) protocol is a series of messaging specifications for the electronic communication of trade-related messages, which the WSO2 ESB supports in combination with the QuickFix/J open source project. The Advanced Message Queuing Protocol (AMQP) is an open standard business messaging protocol originally developed for financial services, but also gaining ground in many other industries. The WSO2 ESB 1.7 has been thoroughly tested and is certified to work with the Apache Qpid implementation of AMQP. Using the WSO2 ESB 1.7, developers in the financial services market can leverage their existing investments in these widely adopted protocols.

Cementing the abilities of the WSO2 ESB for mission-critical applications, the clustering support has been enhanced to allow hot updates of a cluster in a continuously live environment.

In scaling tests on a standard dual-processor server, the WSO2 ESB 1.7 handled loads of up to 2,500 concurrent connections without losing a single message. In the same tests, comparable open source ESBs failed to handle more than one hundred concurrent clients without errors.

WSO2 ESB 1.7 Features
The WSO2 ESB provides a lightweight platform that can route messages with millisecond overhead and can scale to manage thousands of simultaneous connections-on standard server hardware. Version 1.7 is based on the Apache Synapse ESB 1.2 release launched earlier this month (For more information, visit http://synapse.apache.org). The WSO2 ESB is a pure open source project that enhances the Apache Synapse ESB with a full graphical management and configuration console, as well as an integrated registry and repository based on the WSO2 Registry 1.1, which also is being launched.
