RALEIGH, N.C. — Red Hat (Nasdaq: RHAT) has closed on its $420 million acquisition of open source middleware developer JBoss.

JBoss, which is based in Atlanta, will operate as a division of Red Hat.

“Red Hat’s acquisition of JBoss reflects a desire by our global customers to accelerate and expand the use of open source in the enterprise,” said Matthew Szulik, chairman and chief executive officer of Red Hat.

Marc Fleury, who founded JBoss, will lead the division as senior vice president and general manager.

“Joining forces with Red Hat makes absolute sense for JBoss employees, customers, partners and the community as a whole,” Fleury said. “We share a common passion for innovation, technology and open source. Red Hat will give JBoss a platform to grow, so we can both continue to deliver exceptional open source products, services and customer value.”
