3.4.1 Background
During any provider and consumer conversation the topic of virtual machine performance always arises. In some cases this is referred to as one element of a Service Level Agreement (SLA). In this document, the aspect of a tenant’s performance is examined in relation to the three allocation models.
Note: Higher performance levels are defined here as guaranteeing physical resources from the provider virtual datacenter to the consumer. Actual virtual machine performance might vary based upon the application running within the virtual machine. However, guaranteeing required resource availability to a virtual machine provides the best performance.
We have already discussed examples of how to create virtual datacenters based on various use cases. The intent here is to expand on the tenant requirements that may drive decisions to the different allocation models. Thinking about allocation models in the context of performance rather than uptime or availability is just another option.
