GSI Selects Mule ESB as Core Integration Platform for e-Commerce, Multichannel Retailing and Interactive Marketing Offerings

SAN FRANCISCO, CA--(Marketwire - May 19, 2009) - MuleSource, the leading provider of open source service oriented architecture (SOA) infrastructure software, today announced that GSI Commerce Inc. (NASDAQ: GSIC), a leading provider of e-commerce and multichannel solutions, has selected Mule ESB Enterprise as the core integration framework on which to build a standardized service infrastructure.

Key to the ongoing evolution of GSI's e-commerce platform is the ability to integrate core platform capabilities to a wide variety of service integration use cases, and to do so in a cost-efficient, scalable manner that maximizes leverage of existing platform assets while supporting the creation and adoption of new components and services. At the same time, scalability and high availability of the e-commerce platform must continue to be preserved as existing clients experience organic growth and new clients are added to the platform.

"Mule has proven to be a cost effective solution -- allowing us to standardize on a single service integration solution versus rolling dozens of services built several different ways," said Jeffrey Trimm, Principal Architect, GSI Commerce. "It helps us lower our development costs and allows us to respond quicker to our clients' needs."

In evaluating ESB solutions, GSI considered both open source and proprietary solutions. GSI found Mule ESB attractive based on a strong match with its requirements for a service integration framework. GSI also considered Mule ESB's maturity, having been adopted and successfully deployed by thousands of companies. In addition to architectural requirements, total cost of ownership (TCO) was also a factor in selecting a solution. GSI conducted a detailed cost analysis, and Mule's open source subscription model came out on top as delivering the best value.

"GSI takes a pragmatic approach to service development, understanding that internal service integration standards must marry with the reality of a wide spectrum of external service protocols, formats, and standards that exist in the real world," said Phil Bradley, vice president of Sales, MuleSource. "We are pleased that the GSI team has chosen Mule ESB Enterprise as their core ESB and integration platform of choice."
