WHAT
A Resource Group is a logical container in Azure that holds all the related resources for your application — VNets, VMs, load balancers, everything.
💡
WHY
Azure requires every resource to belong to a group. It's the first thing you create in any lab or real project. It lets you manage, monitor, and delete everything together with one action.
⚙️
HOW
You pick a name (saas-lab-rg) and a region (eastus — where Azure's data centres host your resources). All subsequent commands will reference this group with -g saas-lab-rg.
