Hi
There are many type of roles available in Azure . You can check from below link.https://docs.microsoft.com/en-us/azure/role-based-access-control/built-in-roles
Roles can be high-level, like owner, or specific, like virtual machine reader. ... For example, the Virtual Machine Contributor role allows a user to create and manage virtual machines. If the built-in roles don't meet the specific needs of your organization, you can create your own Azure custom roles
