With Infrastructure as a Service (IaaS), you can rapidly model and provision servers and desktops across virtual and physical, private and public, or hybrid cloud infrastructures. Configuring Infrastructure FabricThe IaaS administrator and fabric administrator roles are responsible for configuring the fabric to enable provisioning of infrastructure services. Fabric configuration is system-wide and is shared across all tenants. Infrastructure Source EndpointsInfrastructure sources can include a group of virtualization compute resources, a cloud service account, or a physical management interface. Compute ResourcesA compute resource is an object that represents a host, host cluster, or pool in a virtualization platform, a virtual datacenter, or an Amazon region on which machines can be provisioned. Data CollectionvRealize Automation collects data from infrastructure source endpoints and their compute resources. Fabric GroupsAn IaaS administrator can organize virtualization compute resources and cloud endpoints into fabric groups by type and intent. One or more fabric administrators manage the resources in each fabric group. Business GroupsA business group associates a set of services and resources to a set of users, often corresponding to a line of business, department, or other organizational unit. Machine PrefixesYou use machine prefixes to generate the names of provisioned machines. Machine prefixes are shared across all tenants. Resource ReservationsA fabric administrator creates a reservation to allocate provisioning resources in the fabric group to a specific business group. Configuring Reservation PoliciesWhen a user requests a machine, it can be provisioned on any reservation of the appropriate type that has sufficient 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. Cost ProfilesFabric administrators can associate compute resources and physical machines with cost profiles to enable calculation of a machine’s cost. The cost is displayed to machine owners, requesters, approvers, and administrators at various points in the request and provisioning life cycle. Machine BlueprintsA machine blueprint is the complete specification for a virtual, cloud, or physical machine and is used to determine a machine’s attributes and how it is provisioned. Machine Leases and ReclamationIaaS 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. Machine ReconfigurationvSphere and vCloud Director platforms support reconfiguration of existing machines to modify specifications for CPU, memory, storage, or networks. A machine owner can request a reconfiguration when the machine is in either the On or Off state.
