Amazon is a global commerce, cloud computing, and digital infrastructure platform organized primarily around North America, International, and AWS. Its retail ecosystem includes first-party sales, third-party seller services, advertising, Prime subscriptions, fulfillment logistics, digital content, and devices. AWS provides compute, storage, databases, networking, security, analytics, machine learning, and generative AI services to enterprises, developers, and public-sector customers. Amazon’s scale advantages come from fulfillment density, marketplace liquidity, advertising inventory, recurring Prime engagement, and cloud infrastructure, with current investment focused on AI capacity, automation, and custom silicon.
