What Cloud Computing Is

Cloud computing is the delivery of computing resources over the internet as a service instead of owning and managing all the infrastructure yourself. In this lesson, learners build a clear definition of cloud computing, understand the main ideas behind shared resources, on-demand access, scalability, and pay-as-you-go usage, and learn the terminology needed for the rest of the course.

The lesson also clarifies what cloud computing is not, why businesses adopt it, and how it differs from traditional on-premises IT. This foundation prepares learners for service models, deployment options, architecture, security, and cost control in later lessons.
