Configuring roles
You can also add software components to the infrastructure while setting it up. Finally, you could set up
the chargeback and metering parameters for infrastructure resources during the setup phase and publish the
infrastructure cloud resources for usage by cloud users. Oracle Enterprise Manager helps set up the database or
middleware cloud out of the box in addition to the infrastructure cloud example shown here.
There can be different administration tasks and roles during the cloud setup phase. The cloud administrator can
be someone who sets up the cloud infrastructure including systems, database, or any other cloud resource offered
as a service. A self-service administrator can be the administrator at the business units or any other cloud tenant who
sets up the quota and roles for their users.
Some of the typical tasks associated with cloud administrators are provisioning bare-metal hypervisors, configuring
storage arrays and the network, creating server pools, and defining zones based on functional and operational
boundaries. They also configure the policies and access control of the Software Library for the cloud users.
Self-service administrators define allowable VM sizes, assign quotas to users/roles, define access boundaries, map
roles to zones, set up chargeback plans, and make software available for deployment by self-service users of the cloud.
EM12c supports these typical roles and their common activities out of the box. As you saw in Figure
5-6
, these
roles and policies for users can be customized if needed during the cloud setup process via the Self Service portal.
The customized setup of cloud, user roles, and policies helps automate the provisioning of the resources depending
on the cloud service models. The same automation technology, leveraged by the Self Service portal for provisioning
the resources, is also available via command-line APIs called EMCLI (not discussed in this topic).
Building the Cloud
After your cloud admins have set up the shared resources, self-service admins in the business units or other cloud user
organizations will need to build the complete infrastructure, where they will ultimately deploy their business applications.
