What is an Azure Resource Group?

An Azure Resource Group is a logical container that holds related Azure resources for a solution or application. All resources in a group share the same lifecycle — you deploy, update, and delete them together. A resource group has a specific Azure region but can contain resources from any region. Key properties: every resource must belong to exactly one resource group; resource groups cannot be nested; you can apply RBAC permissions, tags, and policies at the resource group level, which inherit down to resources. Resource groups help organize resources by project, environment (dev/prod), or team, making cost management and access control simpler.
