Vantage Labs launches on Resin software

- Speed, scalability and cost make Resin an ideal solution for Vantage

LA JOLLA, CALIFORNIA -- July 19, 2004 -- Vantage Labs today announced that they will be launching their high availability testing and assessment application systems on Resin software. Vantage Labs is the holding company/research organization that provides core technology components and programs that are used in Vantage Software Solutions, Vantage Learning, and Vantage McCann businesses. Caucho® Technology is a Sun Microsystems J2EE licensee.

Vantage Labs is the world's leading provider of sophisticated knowledge solutions, leveraging advanced Artificial Intelligence and cognitive science research to develop high quality tools and applications which identify, extract, communicate and control knowledge. By building high-performance businesses which apply these tools to benefit education, commerce and government, Vantage improves the way we learn and live.

Caucho® Technology produces Resin, a leading application server used by thousands of corporate, education and government clients. With customers that have large and demanding sites including EBay's half.com, CNet, the American Red Cross, the Toronto Stock Exchange and Salesforce.com, Resin delivers fast and stable performance.

Brian Maguire, Director of Product Development for Vantage said, "We selected Caucho® Resin after evaluating many application server vendors. Caucho's raw speed, scalability features, simplicity, open source model, and cost model made it no contest." Maguire added, "Our high availability assessment applications need to run on a large farm of servers and demand reliability and scalability for enormous loads. Other application servers are just filled with extensive and unnecessary components that add complexity, decrease performance and reliability, and add unnecessary costs. I believe Caucho® is the industry's best kept secret."

Steve Montal, Director of Sales and Strategic Partnerships at Caucho® Technology said, "Our core goal is to provide high performance software that exceeds expectations, even under heavy load situations." Montal added, "We are delighted that Vantage chose Resin to power their high availability testing and assessment application systems and we look forward to working with them."

Eduventures recently selected Vantage Learning as one of the eight most innovative educational technology companies. Vantage provides services in all 50 states, including Pennsylvania, Massachusetts, Virginia, Oregon and Texas. The company provides services to educational leaders, such as The College Board, ACT, Harcourt Educational Measurement, CTB/McGraw Hill and Thomson Learning, as well as industry giants, such as Microsoft, Apple Computer, AOL and Sun Microsystems.

With numerous added features, increased speed and load balancing, Caucho's Resin software is experiencing rapid growth worldwide. Caucho® is active in web services and has support for Apache SOAP. Caucho® has also developed the Hessian binary protocol in an effort to produce fast solutions for the rapidly expanding web services arena.
