Amazon Web Services (AWS) is the world’s most completely defined and broadly used cloud platform adopted around the globe, offering over 175 fully-featured services globally from various data centers. AWS is a platform that offers reliable, flexible, scalable, user-friendly, and cost-effective cloud computing solutions. The AWS platform is built with a combination of Infrastructure as a service (IaaS), Platform as a service (PaaS), and Packaged software as a service (SaaS).

The early version was aimed at helping developers to build applications and tools that allow them to include some of the unique features of Amazon.com into their websites.
