Chutney gets Web services out of a pickle

Two emerging companies are working to make Web services more reliable by releasing products that enhance simple object access protocol (SOAP) functionality.

Chutney Technologies yesterday (29 April) released Apptimizer for SOAP while Parasoft has unveiled SOAPtest.

Chutney's software, compatible with both J2EE and .net, is designed to eliminate bottlenecks resulting from Web services.

The Chutney product line consists of a SOAP Library and Chutney storage engine.

The two work together to eliminate Web services bottlenecks by essentially tapping into an existing SOAP library to identify where the software can reuse data, according to Greg Govatos, vice-president of marketing at Chutney, based in Atlanta, USA.

When a SOAP call is made the SOAP call checks with the Chutney cache, Govatos said. "We mitigate the steps that applications need to perform that function."

Govatos pointed, as an example, to a company that delivers stock quotes across the Internet via the Web services model. Instead of making the system search for stock quotes upon every request, Chutney enables the customer to cache popular results then, in turn, deliver those more quickly.

Bottlenecks occur in pretty much anything that requires a call to databases, mainframes, or other data sources, Govatos said.

Chutney plans to formally announce Apptimizer for SOAP at the upcoming N+I tradeshow next week in Las Vegas. The software will be generally available on 1 June.

Meanwhile on the Web services testing front, Parasoft's SOAPtest tool enables functionality, load and regression testing to find errors in Web services that use the SOAP protocol.

Parasoft is positioning SOAPtest as software to use early in the Web services development lifecycle to ensure that Web services function properly.

SOAPtest can emulate clients and servers to verify that Web services and related components are operating as intended and that they are scaling when need be. According to the California-based company, SOAPtest can pinpoint sources of error.

The software also can be used to validate, query and transform XML as well as to create rules to prevent XML errors from multiplying.

Web services are still young enough that not many customers are experiencing bottlenecks or scalability issues but that is likely to change as more companies deploy Web services, according to Michael Hoch, a senior analyst with consultancy Aberdeen Group.

"Right now there aren't a lot of bottlenecks and problem areas in Web services. But if companies don't take these potential problems into account during the design phase, they'll be shut down pretty quickly when they go live with Web services," Hoch said.
