Introduction to AWS Infrastructure and Cloud Service Models

Navigating the vast ecosystem of cloud computing can feel overwhelming when you are just starting out. Understanding how physical infrastructure translates into virtual resources is the crucial first step to building scalable modern applications. This text-based course guides you through the foundational concepts of cloud computing, comparing IaaS, PaaS, and SaaS models, and mapping them directly to core AWS services. You will transition from a cloud novice to someone who understands how compute, storage, database, and networking components interact. What you'll learn: 1. Understand the fundamental differences between IaaS, PaaS, and SaaS models. 2. Explore core AWS compute options including virtual servers and serverless basics. 3. Configure cloud storage solutions using object, block, and file storage systems. 4. Differentiate between relational and non-relational database services in AWS. 5. Design basic virtual networks with subnets, security groups, and routing. 6. Apply the AWS Shared Responsibility Model to secure cloud infrastructure. 7. Analyze cloud architecture using modern well-architected framework principles. You will begin with essential cloud terminology and deployment models before moving step-by-step through practical AWS infrastructure services. Each section reinforces your understanding with written scenarios, architectural breakdowns, and conceptual exercises. This course is designed for absolute beginners, aspiring cloud administrators, and developers looking for a solid conceptual foundation in AWS with no prior cloud experience required.
