Welcome to Cloud Fundamentals, the perfect starting point for anyone looking to understand how the cloud truly works.

In this course, you’ll explore the core principles of cloud computing, beginning with what the cloud actually is — beyond the buzzwords. We’ll explain how data centers, physical servers, and virtualization come together to form the backbone of modern cloud environments.

You’ll also learn the differences between IaaS (Infrastructure as a Service), PaaS (Platform as a Service), SaaS (Software as a Service), and FaaS (Function as a Service) — with practical examples and demos on real cloud platforms like AWS and Proxmox.

Through easy-to-follow lessons, we’ll break down complex topics such as:

• How virtual machines run inside physical servers

• What a hypervisor does and why it’s critical

• How redundancy and high availability are achieved in the cloud

• The difference between public, private, and hybrid cloud models

• Common cloud computing roles and careers

Unlike most courses that only focus on cloud providers, Nodekloud Academy helps you understand the technology behind the cloud — so you can build, manage, and troubleshoot your own cloud environments with confidence.

By the end of this course, you’ll not only know what the cloud is — you’ll know how it works.
You’ll have a solid foundation to continue your journey as a Cloud Engineer, ready to work with both private and public cloud infrastructures.
