Catalog Item Role Components Description Details
Custom IT
Services
XaaS architects Create and publish
XaaS blueprints on
the XaaS tab.
You can create XaaS catalog items that
extend vRealize Automation functionality
beyond machine, networking, security, and
software provisioning. Using existing
vRealize Orchestrator workflows and plug-
ins, or custom scripts you develop in
vRealize Orchestrator, you can automate
the delivery of any IT services.
Published XaaS blueprints are available
for catalog administrators to include in the
catalog as standalone blueprints, but you
can also combine them with other
components on the Blueprints tab to
create more elaborate catalog items.

You can reuse published components and
blueprints, combining them in new ways to
create IT service packages that deliver
elaborate functionality to your users.

Designing Machine Blueprints
Machine blueprints are the complete specification for a machine, determining a machine's attributes, the
manner in which it is provisioned, and its policy and management settings. Depending on the complexity
of the catalog item you are building, you can combine one or more machine components in the blueprint
with other components in the design canvas to create more elaborate catalog items that include
networking and security, Software components, XaaS components, and other blueprint components.
Space-Ecient Storage for Virtual Provisioning
Space-efficient storage technology eliminates the inefficiencies of traditional storage methods by using
only the storage actually required for a machine's operations. Typically, this is only a fraction of the
storage actually allocated to machines. vRealize Automation supports two methods of provisioning with
space-efficient technology, thin provisioning and FlexClone provisioning.
When standard storage is used, the storage allocated to a provisioned machine is fully committed to that
machine, even when it is powered off. This can be a significant waste of storage resources because few
virtual machines actually use all of the storage allocated to them, just as few physical machines operate
with a 100% full disk. When a space-efficient storage technology is used, the storage allocated and the
storage used are tracked separately and only the storage used is fully committed to the provisioned
machine.
