AWS provides scalable, flexible, and cost-effective cloud solutions used by individuals, startups, and enterprises.

AWS is a subsidiary of Amazon that provides cloud computing platforms and APIs on a pay-as-you-go basis. It allows businesses to run applications, store data, and scale resources without the need for on-premise hardware.
