Description

Introduction of Cloud Infrastructure Fundamentals

Cloud computing offers scalable, on-demand access to a variety of computing resources, allowing businesses to operate more efficiently and reduce costs. The three main service models—Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)—each provide different levels of abstraction and management responsibilities. This course will explore these three core cloud service models in detail, helping you understand their differences, use cases, and when to adopt each model.

Prerequisites

• Basic knowledge of computing and IT concepts.
• Familiarity with internet technologies, networking, and virtualization concepts is beneficial but not mandatory.
• No prior cloud computing experience is required.
