Amazon Web Services is the world's leading cloud computing platform, launched in 2006 as a subsidiary of Amazon.com. AWS pioneered the infrastructure-as-a-service model, fundamentally transforming how businesses build and deploy technology by offering on-demand computing resources over the internet. What began with simple storage (S3) and compute (EC2) services has grown into a comprehensive platform offering over 200 fully featured services spanning compute, storage, databases, analytics, machine learning, artificial intelligence, Internet of Things, security, and application development. AWS operates from 33 geographic regions and 105 availability zones worldwide, providing the most extensive global cloud infrastructure of any provider. The platform powers a vast range of organizations, from startups and small businesses to the world's largest enterprises and government agencies, including Netflix, NASA, Capital One, and numerous Fortune 500 companies. AWS holds approximately 31 percent of the global cloud infrastructure market, maintaining its position as the dominant cloud provider ahead of Microsoft Azure and Google Cloud. Key services include Amazon EC2 for scalable computing, Amazon S3 for object storage, Amazon RDS for managed databases, AWS Lambda for serverless computing, and Amazon SageMaker for machine learning. AWS has been a significant driver of Amazon's profitability, generating tens of billions of dollars in annual revenue and operating as the company's highest-margin business segment.
