Amazon’s admission into the grocery games has forced the companies to find ways to make sure they stay steady in the competition. Whereas Walmart wants to tackle this through increasing the online presence, provide one-day deliveries, as well as store the pick-ups. Kroger is working on the other approach and partnered with Microsoft Azure to fulfill its cloud computing requirements. As Microsoft is challenging Amazon Web Services, Kroger has planned to create digital shelves for increasing store efficiency using Microsoft. It is dealt with the same-day delivery of groceries with self-driving cars that helps in boosting sales.
