What the cloud is, how it works under the hood, and why it changed the economics of IT. You start with the problem the cloud solves, then learn the deployment models and the pricing models.

The service models and building blocks every cloud runs on: IaaS, PaaS, and SaaS, plus compute, storage, databases, and networking, and the modern patterns built on top of them.

Who secures what in the cloud, and how cloud systems stay up. You learn the shared responsibility model, identity and encryption basics, and the patterns behind high availability and disaster recovery.

Where cloud skills lead. The roles teams hire for, how to practice hands-on for free, and which certification to take first, with a clear roadmap toward the AWS Certified Cloud Practitioner as a natural next step.
