IBM has recently eyed both Rackspace (RAX) and SoftLayer as buyout targets, a former IBM exec tells GigaOm. Meanwhile, EMC is said to be uninterested in SoftLayer - Reuters reported yesterday both EMC and IBM have been in talks to buy the company. Rackspace (unlike SoftLayer) is a major backer of the OpenStack cloud infrastructure platform, which IBM just threw its weight behind. The former exec notes IBM's historical preference to flesh out its product lines via M&A. "IBM does not want to fund its own development because past history shows we’re not very good at it."
