IBM, a company that originally made its name out of its leadership in building myriad enterprise hardware (quite literally: its name is an abbreviation for International Business Machines), is taking one more step away from that legacy and deeper into the world of cloud services. The company today announced that it plans to spin off its managed infrastructure services unit as a separate public company, a $19 billion business in annual revenues, to help it focus more squarely on newer opportunities in hybrid cloud applications and artificial intelligence. Infrastructure services include a range of managed services based around legacy infrastructure and digital transformation related to it. It includes things like testing and assembly, but also product engineering and lab services, among other things. A spokesperson confirmed to me that the deal will not include the company's servers business, only infrastructure services.
