Buying and selling goods or services over the internet using electronic transactions. Like a digital marketplace that's open 24/7 from anywhere in the world.
Amazon is the world's largest e-commerce platform, handling millions of transactions daily for products ranging from books to electronics.
E-commerce is a business model (online buying and selling), not a single cloud service. Cloud providers support e-commerce with building blocks like web/app hosting, databases, payments integrations, security, analytics, and content delivery networks (CDNs).
