WSO2 integrates registry with ESB


By David Worthington
June 23, 2008 — 
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.

Aspects allow developers to add arbitrary actions for human-oriented workflows, explained Glen Daniels, director of Java platforms at WSO2, adding that behaviors are defined using a declarative XML configuration. Workflows are visualized through a user interface for state-based life-cycle management, one that displays which states must be satisfied before a workflow can progress beyond the current point.

Users can maintain reliance graphs between resources with dependency views that are derived from WSDL models. Alternatively, dependencies can be added manually and developers may write their own handlers, said Daniels.

“Overall, we’ve done all of the hard work for them. They don’t have to write a lot of code,” he noted.

Underneath the dependency view, the UI now displays arbitrary association types, capturing relationships between resources to make more information available for governance, said Fremantle.

For example, an association can tell the ESB where a back-up service is located.

The registry API now offers transaction access to the registry, enabling the latter to be embedded into runtime systems with automated governance.

Both the ESB and registry are released under the Apache 2 license and may be downloaded free of charge. WSO2 also offers a range of service and support options for each.
