The user needs to log on, and then may assign the token to the resource that was accessed. Multiple users can be assigned directly to specific tenants and behave as if they were included within the tenant.2, authentication information: Confirm the user identity data. such as user name and password, user name and API key, o

These services can be used independently. A typical scenario is that they are used in storage services, but they are often bundled together. In this case, the server will be attached with a network connection (usually) it also provides access to storage. Such bundled services are generally referred to as IaaS, regardless of whether
