Red Hat (NYSE: RHT) executives had more on their mind than their annual “Summit: when they gathered in Boston this week.

They also were acquiring a company.

The world’s top Linux software developer and services firm says it is buying FuseSource, a provider of open source integration and messaging technology.

FuseSource, which is part of Progress Software Corporation, is based in nearby Bedford, Mass.

“This is a technology tuck-in that accelerates work that we are already doing,” Paul Cormier, president of Red Hat’s Westford office, told The Boston Globe.

Red Hat recently announced plans to expand its operations in suburban Boston where many of its development engineers are based.

The deal is the second for Red Hat in recent months. Last October it acquired California-based Gluster.

Financial terms of the FuseSource deal were not disclosed.

Red Hat says FuseSource technology will help the Hatters ”accelerate the delivery of application integration products and services to enterprise customers.”

FuseSource customers include several Fortune 500 companies.

“Application integration software is one of the fastest growing segments of the enterprise software market,” said Craig Muzilla, vice president and general manager of middleware at Red Hat, in a statement. “As cloud computing becomes more prevalent, enterprise customers are demanding greater application integration to enable seamless use of cloud computing. With the addition of FuseSource to our middleware portfolio, we will enable customers to experience greater integration capabilities and flexibility. FuseSource’s technologies, expertise, and commitment to open source make them a great fit.”

Red Hat says FuseSource will augment its own JBoss middleware products and services.

The deal is not expected to “have a material impact” on its financials this current fiscal year, Red Hat said.
