Well, it’s a not a NoSQL acquisition, but Red Hat is expanding its partnership with 10Gen, the company behind the open source NoSQL database MongoDB. Today the two companies announced that teams from both companies are collaborating on the development of best practices and blueprint references for deploying MongoDB on the Red Hat Enterprise Linux operating system, Red Hat’s platform-as-a-service OpenShift and Red Hat’s middleware solution JBoss.

Last year Red Hat and 10gen announced a partnership to bring MongoDB to OpenShift, and Red Hat CEO Jim Whitehurst to told InternetNews.com: “We would be very interested in a NoSQL type database or Hadoop type thing.”

Whitehurst has been open in recent years about his desire to acquire more companies. Last October Red Hat acquired Gluster and Whitehurst has hinted that open source business intelligence vendor Jaspersoft may also be on the menu.

Red Hat recently became the first billion dollar open source company, and it’s now in the mode of trying to show the world that it’s more than just a one trick pony by adding cloud and storage products to its lineup. 10gen is on top of the NoSQL world, with tons of funding and a leading position in NoSQL adoption. Also, unlike many other NoSQL companies, 10gen is following a pure open source business model much like Red Hat’s own. That’s increasingly rare in a market infatuated with the “open core” business model of selling a proprietary enterprise version of an opens source product.

Red Hat and 10gen seems like a match made in heaven, whether as partners or as part of an acquisition.
