PALO ALTO, CA and FREMONT, CA -- (MARKET WIRE) -- September 07, 2006 -- Xcalia, a leading provider of dynamic integration software recognized as a Gartner "Cool Vendor" and Sierra Atlantic, a leader in business process-based integration and enterprise application optimization, today announced a partnership that will give joint customers the ability to enable legacy data migration and integration into current or planned SOA infrastructure.

Organizations with a long heritage of legacy computer systems have an assortment of mainframe applications representing a huge financial and strategic business investment. Industry analysts collectively agree that between 70 to 80 percent of all mission-critical business data is in stored mainframe and legacy systems. One of the most critical challenges businesses face is how to leverage this information in a service-oriented way to deploy composite applications.

"The partnership between Sierra Atlantic and Xcalia will provide our clients with a comprehensive SOA solution," said Brian P. Rogan, Senior Vice President Strategic Business and Marketing, Sierra Atlantic. "This will enable our mutual clients to draw on existing business logic and processes residing anywhere within the enterprise to rapidly assemble solutions for particular problems, increase productivity and flexibility while simultaneously improving responsiveness to changing business conditions."

Three universal business scenarios for mainframe environments where Xcalia and Sierra Atlantic help enterprises make the best of the resources they have today and plan for the future, while protecting the transactional integrity of the application, include:

-- Integrating mainframes resources into SOA model -- Transitioning mainframes to other platforms -- Maintaining multiple systems and managing implementation costs

The collaborative expertise of Sierra Atlantic and Xcalia addresses the key priority for CIO's: the ongoing need to simplify business integration while reducing development and maintenance time and costs. With the advent of SOA, the challenges of integration are even more complex and the limitations of traditional application development and integration solutions are even more problematic.

"Organizations are now beginning to think about applications in terms of business services rather than lines of code. These services need to be mapped with enterprise data and information resources regardless of the content, location, platform or programming language associated," said Pierre Violo, Xcalia CEO. "Data and services must be reusable and easily accessible. Applications need to be detached from the underlying systems and infrastructure for increased adaptability to new business requirements and ease of maintenance. We are excited that Sierra Atlantic shares this same vision and is committed to helping customers compose applications using Xcalia technology."
