Amazon Web Services (AWS) provides on-demand cloud computing platforms and APIs to individuals, companies, and governments, allowing them to access virtual computer systems and computer-hosted services through the Internet. AWS began in 2006 with a focus on providing web service infrastructure for Amazon's own retail division, and has since expanded into a broad range of cloud-based services including computing, storage, networking, database, analytics, application services, and deployment/management tools. With AWS, users pay only for resources consumed, avoiding up-front costs and gaining elasticity to scale up as needed.
