Amazon Web Services (AWS)

AWS commands 31% global IaaS market share and $107B in annual revenue as of 2025, making it the undisputed cloud leader. Over 1 million active customers, including Netflix with 270M subscribers and a $600M CIA contract, rely on its 12,000+ product marketplace. Amazon Bedrock and SageMaker position AWS as the default enterprise AI platform, while its 2006 origin with S3 and EC2, detailed in Brad Stone's 'Amazon Unbound,' cemented its legacy. AWS outperforms #2 Azure by adding more than $30B in annual revenue, maintaining a wide lead.
