Machine Leases and Reclamation on page 29
IaaS provides two mechanisms for controlling resource use and controlling costs. Leases provide
access to a machine for a limited period. By using the reclamation process, a tenant administrator can
identify underused resources and reclaim them from their owners.

Scaling and Reconguring Deployments on page 30
You can scale provisioned deployments to adjust to changing workload demands. You use the scale in
or scale out actions for horizontal scale, and the machine recongure action for vertical scale. You
govern scale and recongure actions by using entitlements, approval policies, or by designing
constraints directly into blueprints.
Configuring Infrastructure Fabric
The IaaS administrator and fabric administrator roles are responsible for conguring the fabric to enable
provisioning of infrastructure services. Fabric conguration is system-wide and is shared across all tenants.
An IaaS administrator creates an endpoint to congure access to an infrastructure source. When the
connection to an infrastructure source is established, vRealize Automation collects information about the
compute resources available through that source. The IaaS administrator can then organize those resources
into fabric groups and assign a fabric administrator to manage each group as well as cross-tenant
conguration such as machine prexes.
A fabric administrator can create reservations to allocate provisioning resources in the fabric group to
specic business groups that the tenant administrator created during tenant conguration. Optionally, the
fabric administrator can congure reservation, network, or storage reservation policies. For example, they
can create a reservation policy to control placement of provisioned machines.
When the fabric administrator has created reservations, the IaaS architects can create and publish machine
blueprints for reuse in application blueprints and for catalog administrators to make available in the service
catalog.
Infrastructure Source Endpoints
Infrastructure sources can include a group of virtualization compute resources or a cloud service account.
An IaaS administrator congures an infrastructure source by specifying the endpoint details and credentials
that vRealize Automation can use to communicate with the source.
vRealize Automation collects information about all congured infrastructure sources at regular intervals.
This information includes virtualization hosts, templates, and ISO images for virtualization environments;
virtual datacenters for vCloud Director; and regions and machines provisioned on them for Amazon.
