Cloud Concepts
An overview of the first AWS Cloud Practitioner domain: cloud computing fundamentals, the benefits of the AWS Cloud, the Well-Architected Framework, migration strategies, and cloud economics.
Cloud Concepts is the first domain of the AWS Certified Cloud Practitioner course, and it sets up the vocabulary every later domain relies on. Before you compare services, reason about security, or read a pricing page, you need a clear picture of what the AWS Cloud is and why organizations move to it. This domain builds that picture from the ground up, then connects it to the business reasons behind cloud adoption.
Cloud Concepts carries 24% of the CLF-C02 exam, the second-largest share, so the ideas here come up often. Most of them are also the base for questions in the other 3 domains.
What This Domain Covers
- what cloud computing is and how it differs from running your own on-premises hardware
- the service models IaaS, PaaS, and SaaS, and the deployment models that sit behind them
- the 6 advantages of the AWS Cloud, plus availability, elasticity, and agility
- the AWS Well-Architected Framework and its 6 pillars
- cloud migration: the AWS Cloud Adoption Framework, the common migration strategies, and the AWS Snow Family
- cloud economics: fixed versus variable cost, total cost of ownership, rightsizing, and economies of scale
Why It Matters
Many questions in the later domains assume you already speak this language. Once you can explain on-demand delivery, elasticity, managed services, and the move from fixed cost to variable cost, a large share of beginner-level AWS questions stops being confusing.
This domain also introduces the pattern the whole certification returns to: AWS takes on the routine infrastructure work so your team spends more time building and improving the workloads that matter to the business. Keep that idea in mind and the rest of the course reads as variations on it.
