Table 5‑6. Daily Cost Drivers
Cost Driver Calculated Cost
Memory Memory (GB) on the physical machine multiplied by the daily memory cost per gigabyte specified
in the cost profile associated with the machine
CPUs Number of CPUs on the physical machine multiplied by the daily CPU cost specified in the cost
profile associated with the machine
Blueprint cost The value for daily cost specified in the machine blueprint is added to the total cost of the
machine.
This value can represent a markup for using the machine in addition to the resources consumed
by the machine.
Storage cost specified in a cost profile is not taken into account for physical machines. If you assign a
cost profile that includes a value for storage cost to a physical machine, it is ignored. You can account for
the cost of using storage in the daily cost specified in the blueprint for the physical machine.
Lease cost is calculated as daily cost multiplied by the total number of days in the lease period, if
applicable.
Managing Machine Leases
Tenant administrators or business group managers can use leases to place time limits on resource
consumption.
Tenant administrators or business group managers can optionally define a lease duration when creating a
blueprint.
n
If a blueprint does not specify a lease period, machines are provisioned from that blueprint with no
expiration date.
n
If a blueprint specifies a single value for lease duration, machines are provisioned from that blueprint
with the lease duration specified in the blueprint.
n
If a blueprint specifies a range of possible lease durations, a user can select the desired lease
duration when submitting the machine request. Machine requests can be subject to approval based
on the requested lease duration.
The lease duration can be changed after a machine is provisioned. A typical use case is for a machine
owner to extend the lease past its original expiration date. The following considerations apply to modifying
the lease on a provisioned machine:
n
Users must be entitled to the Change Lease action to modify a lease.
n
The new expiration date is not subject to the constraints on lease duration specified in the blueprint.
n
Tenant administrators or approval administrators can create approval policies of the type Service
Catalog - Resource Action Request (Change Lease). The policy can be configured so that approval is
always required for lease modifications, or approval can be conditional based on criteria such as the
new lease duration or the cost of the machine.
Tenant administrators can also request that a machine owner release a provisioned machine for
reclamation, which might result in a shortened lease period.
