Amazon Web Services (AWS)

AWS invented the modern cloud computing market in 2006 with S3 and EC2, and remains the undisputed market leader with 31% global IaaS market share and $107B in annual revenue as of 2025. Over 1 million active customers rely on AWS, including Netflix (which serves 270M subscribers entirely on AWS), Airbnb, and the CIA ($600M intelligence cloud contract). The AWS marketplace lists 12,000+ software products, creating a gravitational pull that makes migration increasingly difficult. Amazon Bedrock (multi-model AI API) and SageMaker (ML platform) position AWS as the default choice for enterprise AI deployment. The origin story of AWS — born from Amazon's internal infrastructure — is told in Brad Stone's 'Amazon Unbound'.
