Apple is buying and deploying an increasing amount of IBM technology for internal use, in a sign of how the vendors’ mobile enterprise partnership is spreading to new areas, sources familiar with the matter told CRN this week.

Apple is using IBM software and hardware in its retail platform and in its corporate data centers, according to the sources.

And:

“Apple and IBM will not call out this work as part of the partnership, but there is momentum at Apple to adopt more of the IBM stack,” a source familiar with the partnership told CRN, speaking on condition of anonymity because the details are confidential. “IBM is becoming one the top software vendors to Apple.”

And:

IBM has an internal team of about 25 salespeople that focuses on selling technology to Apple. That team is forecasted sell $82 million in IBM technology to Apple for fiscal 2016.

Not a huge number for either company, but certainly a sign that the relationship is burgeoning. The headline from the linked article was:

Not sure I buy that Kool-Aid part. Not seeing anything here that makes me thing IBM is changing Apple’s thinking. To me, this seems like smart business for both sides.
