Sonic Software Tops InfoWorld Product Round-Up of Enterprise Service Bus Offerings; Sonic SOA Suite Hailed as the ''Best Overall for Larger-Scale SOA Implementations''.

BEDFORD, Mass. -- Sonic Software (www.sonicsoftware.com), the inventor and leading provider of the enterprise service bus (ESB), today announced that Sonic ESB(R) and the Sonic SOA Suite(TM) have been named "the most powerful, flexible, and scalable ESB" in a comprehensive ESB product round-up by InfoWorld magazine. The review appears in the July 25 issue of InfoWorld and is available online at http://infoworld.com/article/05/07/22/30FEesb_1.html.

The InfoWorld review states: "An ESB must be able to improve access and control over application resources, streamline development, and ultimately reduce integration costs over the long term. Among the products reviewed here, Sonic's SOA Suite is best equipped to achieve these goals on an enterprise scale. Sonic SOA Suite may be the most well-rounded and mature ESB solution in the marketplace today."

The Sonic Continuous Availability Architecture(TM) (CAA) was highlighted by InfoWorld as a way companies can reduce their "reliance on costly hardware as a hedge against system failures." Sonic CAA is a software-based approach for providing high availability and guaranteed message delivery.

"Sonic Software not only pioneered the ESB market, we continue to set the standards for innovative technology and delivering real-world customer value with capabilities like the Sonic Continuous Availability Architecture," said Greg O'Connor, president of Sonic Software. "While companies like IBM and BEA Systems are cobbling together ESB products, Sonic has a proven and extensive track record of helping organizations achieve their business objectives with cutting edge SOA infrastructure software."

Introducing the first ESB in 2002, Sonic Software was one of the first software vendors to recognize the need for a new kind of infrastructure capable of connecting, mediating and controlling large-scale networks of services. The leading industry research firms, influential publications, industry competitors, and most importantly enterprise customers have validated Sonic's early vision, recognizing ESB as critical infrastructure for supporting enterprise SOA requirements.
