Resource Group
In plain terms
A logical container for related cloud resources.
Going deeper
A resource group bundles related cloud resources so they can be managed, deployed, and billed together. It organizes cloud assets by project or lifecycle.
Under the hood
Eases access control, tagging, and teardown; an Azure concept (AWS uses tags/stacks similarly).
Examples
Azure resource groups, organizing resources, grouped deployment/cleanup.
Think of it like...
Like a labeled box holding all the items for one project together.
