WSO2 integrates registry with ESB

NEW YORK — An open-source developer of enterprise service buses (ESB) has integrated the latest version of its ESB with a registry that allows customers to implement their own custom governance rules and policies.

WSO2 announced today at the SOA World Conference & Exposition that WSO2 ESB 1.7 and WSO2 Registry 1.1 had become generally available. The ESB is rooted in Apache Synapse; WSO2 adds its own graphical configuration and management console, and with this release, includes an integrated registry.

WSO2 ESB 1.7 inherits a bevy of new features from the Apache Synapse 1.2 project. Many of those target ESB performance and stability, including connection pooling to increase its database scalability, dynamic routing, lossless handling of large messages over HTTP at high concurrency rates, and clustering to allow the ESB to be reconfigured in a live environment without any downtime.

“Customers asked for a graceful restart model that doesn’t lose [message] payloads,” said Paul Fremantle, CTO of WSO2. He added that messages are also managed differently in memory: The ESB does not build a full memory tree unless it is forced to.

Meanwhile, for the financial industry, the ESB now allows fixed transport through the Financial Information Exchange protocol, or FIX, which is a series of messaging specifications used for electronic trading, and the related open standard Advanced Messaging Protocol.

Also new in this release are the Hessian Web service protocol and several protocols for supporting legacy connectivity.

Prior versions of the ESB included a “quick-and-dirty” built-in repository to store metadata, said Fremantle, but it lacked the governance, life-cycle and validation capabilities that are built into the new registry.

WSO2 Registry 1.1 includes WSDL validation, and it establishes three extension points that provide developers with a plug-in approach to linking resources as well as permitting users to create their own policies and rules. The cumulative effect is that the ESB may now be used as a policy enforcement mechanism, said Fremantle.

Of the three extension points, “aspects” are used to define custom behaviors, “filters” intercept standard behaviors and can be triggered by properties such as time-of-day, and “handlers” decide what to do with them.
