Unlike standard IAM member accounts, service accounts are used by applications, services, or VM instances and not people. Nonetheless, the two types of accounts share many of the same features, including the ability to be assigned pre-defined or custom roles. But, of course, there are differences such as the technique for associating a VM instance with a service account.
In this hands-on lab, you’ll work with service accounts in a variety of ways: creating, editing, disabling, enabling, assigning IAM roles, and attaching a service account to a VM instance.
