service must define hardware requirements and the amount of resources
utilized during execution. The broker stores the required operating system
(Operating System); CPU utilization, consisting of number of nodes, cores,
and clock speed (CPU); and memory utilization in gigabytes (RAM). On suc-
cessful publication, the service can be flagged for public viewing (Published).
The interface used to publish virtual machines is shown in Figure  11.6.
Using the provided interface, the service provider specifies the location of
the virtual machine instance using an identifier given by the cloud provider
(Amazon ID). The instance types that each virtual machine supports are also
provided (Instance Types); from the instance type, cost and the hardware
specification of each virtual machine can be determined.
The interface used to invoke services is shown in Figure 11.7. Through
this interface, a user is able to give a descriptive name to a job for iden-
tification purposes. Users then select from published resources to create
a pool of hardware; any number of published virtual machines can be
added to the pool. Optionally, users can also select from a list of public
(and their private) software services (Application Modules). Once cloud
resources and application modules are selected, the service can be invoked
by clicking the “Submit Job” button. During the deployment process, the
selected pool of resources is allocated and made ready for HPC execution.
If a software service has been selected, resources are selected and config-
ured for the application. The user is then directed to the graphical inter-
face generated using the automated interface generation parser, exposing
the service controls.
