AWS Certified Developer - Associate Guide

Cloud computing is the on-demand delivery of computing resources, such as servers, storage, networking, databases, and other services, over the Internet. Its pay-as-you-go pricing means that you pay only for the services you use, which reduces or eliminates your organization’s total cost of ownership and lowers operating costs. Cloud computing enables you to run your infrastructure more efficiently: it enables faster business innovation, offers flexibility to scale as your business needs change, and helps create economies of scale.
