As Amazon keeps growing, Microsoft is getting involved with ever more retailers. On Tuesday Microsoft said it has signed a multiyear deal with Walgreens Boots Alliance.

Amazon's core business still lies in e-commerce — it has expanded in brick-and-mortar retailing through Amazon Go Stores, its Whole Foods acquisition and other efforts — and at times that's proving to be an advantage to Amazon's competitors in the cloud business. In the case of Walgreens, Amazon's recent push into health care looms large. Although the company has kept its intentions closely guarded, it's making moves like acquiring online pharmacy PillPack and teaming up with J.P. Morgan and Berkshire Hathaway on a long-term plan to improve care and reduce costs for employees.
