How to delete a Resource Group in Azure safely?

Hello,

We have once Subscription in Azure with multiple Resource Groups in that subscription.

Because we do not have any need for some of those Resource Groups anymore we would like to delete them, but will it affect other resource groups? In other words, can we delete a resource group without affecting other resource groups? I read somewhere that some resources can be shared between resource groups , and I do not know how to find those resources.

Thank you.

    Hi @reza admin

    Deleting a resource group permanently deletes all resources within it. This includes virtual machines, databases, storage accounts, and any other resources contained in the group. Note that:

    Resources can only belong to one resource group.

    Resource groups are not nested, so deletion affects only the selected group.

    Resources can connect to resources in other resource groups, but they do not share the same lifecycle. To check for shared connections, you will need to review the dependencies of the resources in the resource group you plan to delete. This can often be done through the Azure portal by examining the properties of each resource.

    You can use Azure PowerShell or the Azure CLI to manage your resource groups and resources. Before deletion, you can list resources and check their dependencies to ensure that no critical connections will be lost.

    Once you are certain that deleting the resource group will not affect other resources you need, you can proceed with the deletion using the Azure portal, Azure PowerShell, or Azure CLI.

    Always ensure that you have backups of any important data before proceeding with deletion, as this action is irreversible.

    Hi Rez,

    You can have resources deployed to different regions but contained with a resource group in a different region. But you can't have a resource appear in multiple resource groups.

    You can have a resource from one resource group reliant on another resource from another resource group but that means there is a shared connection.
