About delete Azure resource group named "DefaultResourceGroup-EUS"

Question

Azure resource group named "DefaultResourceGroup-EUS" was automatically created in may resource group list. There is any problem if i delete it and why?

Answer 1

"DefaultResourceGroup-EUS" is typically created automatically by certain Azure services that need to place resources in a group for management purposes. The "-EUS" suffix suggests that the resource group is associated with the East US region. While you can delete this resource group, you should be aware that it may disrupt any services that depend on the resources within that group. For example, if there are virtual machines, storage accounts, or other resources in this group that are being used by your applications or services, deleting the resource group will delete these resources as well, which could cause downtime or loss of data. As for why this resource group is automatically created, it's often because certain services in Azure need a resource group to manage their resources. For example, Azure Security Center, now known as Microsoft Defender for Cloud, automatically creates a resource group to store its resources, such as security recommendations and alerts. If this is the case, deleting the resource group may disrupt these services.
