MuleSource and OpSource Announce Technology Partnership

SAN FRANCISCO and SANTA CLARA, Calif. – September 19, 2007 – MuleSource, the leading provider of open source infrastructure and integration software, and OpSource™, the SaaS delivery experts, today announced a new technology partnership that takes advantage of the expertise at both companies to provide enterprise customers with a single resource for software integration and on-demand services.

Integration challenges frequently plague companies who choose to offer their services via the on-demand model. Discovering that integration “in the cloud” is much more complex than behind the corporate firewall, businesses seek on-demand providers who can deliver SaaS in a stable on-demand delivery environment. As technology partners, MuleSource and OpSource will combine complementary technologies to ease the transition for new customers while providing the robust, scalable infrastructure that existing customers require.

Mule is the world’s most widely used open source Enterprise Services Bus (ESB) and integration platform while OpSource already delivers SaaS for more than 200 software and Web companies—from established leaders like Business Objects and Visual Mining to innovative new on-demand companies like Boomi and Zipidy. Through this partnership, MuleSource becomes the integration-as-a-service platform of choice for OpSource. In turn, using OpSource On-Demand™, Mule safely scales to deliver millions of services every day, 24/7/365.

In addition, MuleSource has partnered with OpSource to deliver a new hosted subscription offering, MuleOnDemand. Launched yesterday, MuleOnDemand allows enterprises to securely move and manage data inside and outside their organizations using Mule for data and services “integration in the cloud.” Delivered by OpSource, MuleOnDemand enables businesses to connect their existing services with third-party applications on the Web or with partner sites.

Dave Rosenberg, CEO of MuleSource, said, “Our partnership with OpSource is a unique, reciprocal arrangement between two industry leaders. OpSource has selected Mule as its own integration solution, primarily due to Mule’s scalability and adaptability. In combination with our new MuleOnDemand offering, no other integration solution can adapt so seamlessly to serve OpSource’s wide range of customers.”

Treb Ryan, CEO of OpSource said: "As the leader in Web application delivery, our goal is to create an ecosystem that offers a complete, robust integration platform for software and Web companies taking part in the SaaS revolution. With MuleSource, we’ve jointly created the enterprise architecture of the future—a combination of open source and on-demand services that enable deeper third-party integration and architecture flexibility. This allows the rapid creation of new, innovative on-demand solutions."
