Create and

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 workows 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.

Designing Machine Blueprints
Machine blueprints are the complete specication for a machine, determining a machine's aributes, the
manner in which it is provisioned, and its policy and management seings. 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-Efficient Storage for Virtual Provisioning
Space-ecient storage technology eliminates the ineciencies 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-
ecient technology, thin provisioning and FlexClone provisioning.
When standard storage is used, the storage allocated to a provisioned machine is fully commied to that
machine, even when it is powered o. This can be a signicant 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-ecient storage technology is used, the storage allocated and the storage
used are tracked separately and only the storage used is fully commied to the provisioned machine.
