Before touching any specific Azure service, you need the handful of organizing concepts everything else in this course sits on top of. This module is that on-ramp: it's short, but skipping it makes every later module harder than it needs to be.
It starts with a quick, practical overview of what Azure actually is and the core service categories it offers. From there it covers subscriptions and resource groups — how Azure organizes everything you create, and the hierarchy that billing, access, and management all key off of — and regions and availability zones, since where a resource physically lives affects its latency, resilience, and compliance. It closes with the two ways you'll actually work in Azure day to day: the Azure Portal for a visual, clickable view of your environment, and the Azure CLI for scripting and automating the exact same operations.
Watch the lessons in order, then continue on to Identity & Access Management.
A fast, five-minute tour of what Azure is and the main service categories it offers — compute, storage, networking, and databases — so the rest of this course has somewhere to hang.
How Azure organizes what you create: subscriptions as the billing and access boundary, resource groups as the container you'll manage most things through, and how the two relate.
How Azure's physical infrastructure is organized into geographies, regions, region pairs, and availability zones — and why choosing the right one matters for latency, resilience, and compliance.
The fundamentals of managing Azure infrastructure from the command line: installing and signing in, the core command structure, and running the same operations you'd otherwise click through in the Portal.
