A template spec is a new resource type for storing an Azure Resource Manager template (ARM template) in Azure for later deployment. This resource type enables you to share ARM templates with other users in your organization. Just like any other Azure resource, you can use role-based access control (RBAC) to share the template spec. Microsoft.Resources/templateSpecs is the new resource type for template specs. It consists of a main template and any number of linked templates. Azure securely stores template specs in resource groups. Template Specs support versioning. To deploy the template spec, you use standard Azure tools like PowerShell, Azure CLI, Azure portal, REST, and other supported SDKs and clients. You use the same commands as you would for the template.
