The apps will begin to arrive this fall, and IBM will resell iPhones/iPads containing them to clients worldwide.
The companies also plan to develop IBM cloud services optimized for iOS. Targeted markets include security, mobile device management (MDM), and big data/analytics. New enterprise-focused AppleCare services will be offered, as will "new packaged offerings from IBM for device activation, supply and management."
Apple, which maintains an outsized share of enterprise mobile hardware activations, has tried hard to grow its business footprint during the Tim Cook era. Aside from any value provided by the new apps/services, Big Blue's credibility and relationships with Global 2000 firms should provide a shot in the arm for Apple's efforts.
As for IBM, the deal adds to a mobile software/services push that has already resulted in a string of acquisitions and product launches.
Update: Tim Cook, discussing the deal with re/code: "We’re good at building a simple experience and in building devices ... The kind of deep industry expertise you would need to really transform the enterprise isn’t in our DNA. But it is in IBM’s."
