Before touching a single service, it helps to understand what "the cloud" actually is: computing resources such as servers, storage, and databases delivered over the internet and paid for by use. You'll learn the three service models (IaaS, PaaS, and SaaS), the deployment models (public, private, hybrid, and multi-cloud), and how providers organize their data centers into regions and availability zones.
You'll also meet the shared responsibility model, which defines what the provider secures and what remains your job, and take a first look at how AWS, Microsoft Azure, and Google Cloud compare. Watch the videos in order, then move on to Linux once the vocabulary feels familiar.
A beginner-friendly look at what cloud computing is and how it changed the way people and companies access computing services.
The three major service models, what each one manages for you, and how to tell which one fits a given job.
Public, private, hybrid, and multi-cloud: how they differ and how organizations choose between them.
Who secures what: the split between the cloud provider and the customer, shown through AWS. Azure and Google Cloud follow the same principle.
How AWS organizes its global infrastructure into regions and availability zones, and why workloads are spread across them. Azure and Google Cloud use the same idea.
