Cloud Service Categories: Understanding IaaS, PaaS, and SaaS

Moving to the cloud requires a clear understanding of how different services operate and where your responsibilities lie. Without a solid grasp of fundamental cloud service categories, choosing the right architecture for your applications can be overwhelming.\n\nThis text-based course guides you through the foundational pillars of cloud computing—Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). You will learn how to evaluate these models, understand the shared responsibility model, and explore modern serverless and containerized alternatives.\n\nWhat you'll learn:\n- Learn the core differences between IaaS, PaaS, and SaaS with real-world architectural scenarios.\n- Understand the shared responsibility model to identify what security tasks you manage versus the cloud provider.\n- Explore modern serverless (FaaS) and container-based deployment options in contemporary cloud platforms.\n- Master the criteria for selecting the most cost-effective and scalable service model for your business needs.\n- Practice evaluating cloud service architectures through written case studies and practical decision-making exercises.\n\nYou will start with essential cloud terminology and the evolution of cloud computing before diving into detailed breakdowns of each service category. Through clear written explanations and structured analysis, you will build the confidence to map business requirements to the correct cloud service model.\n\nThis course is designed entirely for beginners, with no prior cloud computing experience or technical background required.\n\nStart reading today to build a strong foundation in modern cloud architecture.
