VMware vCloud Director Evaluator’s Guide

5.2 Compute and Storage Infrastructure in the Cloud

Once you have added vCenter servers, you can now take the resources that the vCenter exposes and create

cloud constructs using them. VMware vCloud Director treats vCenter and vSphere resources as a giant pool

of resources.

The ﬁrst cloud infrastructure object we will create is called a Provider Virtual Datacenter or Provider VDC.

A Provider VDC is a combination of compute and storage resources. You can take compute and storage

resources with speciﬁc characteristics, such as cost and performance, and combine them to create a Provider

VDC. When you do this, you can logically tier your pool of compute and storage resources into multiple service

oerings, each implemented by one or more Provider VDCs.

Each Provider VDC will have an SLA

and cost

associated with it and is intended to be a shared resource. You

will see later in this evaluation how multiple Organizations can use resources from Provider VDCs.

As system administrators, IT users are pooling resources together and creating virtual datacenters. VMware

vCloud Director calls these pooled resources Provider VDCs, because in the private cloud, IT is acting like a

service provider within the enterprise datacenter.

Figure 5-2-1.

For example, you can create the following tiers of service (Provider VDCs):
