3.0 Terminology

business group

An association of one or more users with the resources (workload templates, service levels, and networks) from which they can build business services. Each business group supports a sponsor assignment for financial approval. A user must be a member of a business group to request a business service.

A business group might represent a cost center, department, or company.

business service

A collection of workloads that are deployed together.

host

A Virtual Machine (VM) host. In Cloud Manager, a host can represent a single host or a cluster.

host group

A collection of hosts with the same hypervisor technology, operating system version, storage repositories, and networks. All hosts in a group provide the same level of service for a workload.

service level

The level of service associated with a workload. A service level identifies the class of hardware (host group) used to host a workload as well as objectives that provide specific measurable characteristics for the workload such as availability, throughput, frequency, response time, and quality. The cost of a service level is determined by the cost of its host group and objectives.

service level objective

A measurable characteristic such as availability, throughput, frequency, response time, or quality. Each of these characteristics typically has multiple objectives that identify a different level of service.

For example, you might define three availability objectives (97%, 98%, and 99%) and associate them with different service levels (Silver, Gold, and Platinum). By associating different costs with the objectives, you can establish the desired cost structure for your service levels.

sponsor

The member of a business group who is responsible for financial approval of the group’s business services.

workload

A virtual machine.

workload template

A template used to create a workload. The template defines the VM template from which the workload is created and allows for customizing of the VM template settings to increase or decrease the resources (vCPUs, memory, disk storage, and networks) allocated to the workload.

zone

A PlateSpin Orchestrate Server and its associated resources (VM hosts, VM templates, and so on).
