Charles King, an analyst at Pund-IT, said Linux was once seen as something that could push Microsoft's goal of moving quickly into the data center . "That, obviously, hasn't happened," he said. Instead, Linux has become a migration platform mostly for Unix and IBM "has leveraged it very effectively in the mainframe as well."
Major vendors like Oracle are also creating "their own walled gardens" of Linux to preserve competitive advantage, said King -- something he expects to continue.
He believes Linux has a strong future in the data center, "but I haven't heard, I guess what you would call, a statement of direction of where Linux goes from here."
