Will WSO2 become a new industry standard?

WS02, a hard-working Sri Lanka start-up that’s writing a complete open source middleware platform for Web Services, funded by Intel Capital, is expecting WSO2 to become a new industry standard. It's company CEO Sanjiva Weerawarana says the company is creating a new platform that will hopefully compete on equal basis with the existing comprehensive SOA platforms on the market.

The second phase of this project is an ultra-lightweight ESB (Enterprise Service Bus) that the company claims will rewrite the rules for ESB design. It was created to simplify SOA implementation and usually ESBs are architected to support applications in an intranet with Web Services being at best an afterthought requiring another software layer.

So WSO2 rethought the ESB from scratch with Web Services in mind, beginning with a JVM and focused around an XML model. The result is supposed to be able to route messages with only sub-millisecond overhead – 10x less than other people’s – and scale to manage thousands of simultaneous connections.

Weerawarana was with IBM Research previously, and had a lot to do with IBM’s Web Services strategy, such as leading most of its WS initiatives. He says existing ESBs are built often using existing layers like J2EE, servlets and EJBs, which creates performance issues, complexity and conversion costs.

He’s referring to things like BEA Aqualogic, Sonix ESB, IBM WESB, CapeClear ESB, ServiceMix, Mule and JBoss ESB.

It is also the first ESB to be based on the Apache Synapse 1.0 Web Service management and integration broker released at the same time. (WSO2 is very tight with Apache Web Services, providing the leading contributors.)

WSO2’s ESB extended the Apache Synapse XML router and mediation engine with an integrated registry and simple graphical interface so administrators can connect, manage and transform Web Service interactions across their networks.

The Apache Synapse project, an outgrowth of the Apache Incubator project, built a flexible, high-performance SOA framework around XML and Web Services.

The company says the ESB can instantly virtualize services. Users can literally route, version, load balance, log, monitor and also manage services without changing their application code at all.

The company’s first priority, however, is interoperability, and so is designed to work with any XML, HTTP or JMS middleware, including .NET.

It says it’s aiming at much wider integration than just Java.

To date, WSO2 has seen “hundreds of thousands” of free downloads of its initial product, an Apache Axis 2-based Web Services Application Server, and has collected 25 paying customers, including, it says, at least one Fortune 100.

Intel provided the first $4 million in funding, which will see it through next year. It’s going to start casting about for another round by December. It’s got a few of years of work left to get through its product wish list.

WSO2 is looking ahead to a Mashup Server written in JavaScript this fall. It expects to have an external Web Services Registry this year and it’s working on Web Service management. Expected to follow are business rules, governance and policy, security and a portal all based on its Web Services Framework.
