The acquisition  -- IBM's largest ever – highlights the company's efforts to increase subscription-based software offerings as demand for mainframe servers and software declines.

"The acquisition of Red Hat is a game-changer. It changes everything about the cloud market," IBM CEO Ginni Rometty said in a statement. "IBM will become the world's #1 hybrid cloud provider, offering companies the only open cloud solution that will unlock the full value of the cloud for their businesses."
