Amazon owns the AWS cloud business and the Prime subscription service.
Amazon Web Services, usually called AWS, provides cloud infrastructure and related services to businesses, governments, developers, and organizations. Amazon Prime is a consumer subscription program that combines benefits such as shipping, video entertainment, and other services, with features varying by country.
Amazon began as an online bookseller in 1994 and expanded into a broad marketplace, logistics network, digital media company, device maker, and cloud provider. AWS became especially important because enterprise cloud services can produce substantial operating income alongside Amazon’s lower-margin retail operations.
Amazon’s market capitalization reflects the combined expectations for these different businesses rather than just online shopping. A common confusion is assuming AWS is a separate publicly traded company; it is a business segment of Amazon, and its financial results are included in Amazon’s corporate reporting.
