Conguring Reservation Policies on page 30
When a user requests a machine, it can be provisioned on any reservation of the appropriate type that
has sucient capacity for the machine. You can apply a reservation policy to a blueprint to restrict the
machines provisioned from that blueprint to a subset of available reservations.

Machine Blueprints on page 30
A blueprint that contains a machine component species the workow used to provision a machine
and includes information such as CPU, memory, and storage. Machine blueprints specify the
workow used to provision a machine and include additional provisioning information such as the
locations of required disk images or virtualization platform objects. Blueprints also specify policies
such as the lease period and can include networking and security components such as security groups,
policies, or tags.

Machine Leases and Reclamation on page 31
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.
n
Scaling and Reconguring Deployments on page 32
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.
