Walmart and Amazon are competing for e-commerce supremacy. While Amazon has established an efficient online distribution network and changed customer expectations, Walmart remains a more recognizable brand and is investing heavily in its online business. Both companies use information technology like cloud computing, mobile apps, and smart home devices to refine their strategies and offer customers low prices, extensive product selection, and fast delivery options like same-day delivery. The battle between these two giants will likely allow both to be successful by continuing to satisfy changing customer needs through technology and innovation.
