Virtual data centers provide an environment where virtual machines can be stored, deployed, and operated. Selecting a Virtual Private Cloud OnDemand service for the first time provisions your first virtual data center (with 2.6vGHz vCPUs), a gateway, and routed network automatically. Virtual Infrastructure Administrators can create additional virtual data centers in Virtual Private Cloud OnDemand.

Expand the Virtual Data Centers pane to view and manage the virtual data centers in your environment.

Virtual Data Center Pane

The Virtual Data Centers pane displays the status of each virtual data center deployed for the selected location:

Online Virtual Data Center Icon

Ready and usable: the virtual data center was created successfully; it is available for use, such creating and managing virtual machines.

Virtual Data Center Status Icon

Busy and usable: an operation is running for the virtual data center; for example, it is being renamed. However, users can still access it to perform tasks, such as creating and managing virtual machines.

Busy Virtual Data Center Icon

Busy and unusable: the virtual data center is busy completing an operation and cannot be used until that operation finishes; for example, it is being created or deleted.

Offline Virtual Data Center Icon

Unavailable: an error has occurred affecting the virtual data center and it cannot be used.

For assistance with an unavailable virtual data center, file a support request. See Account Support in vCloud AirVirtual Private Cloud OnDemand Getting Started for information.

Because a virtual data center creates artificial limits on operational abilities, customers question why they should create multiple virtual data centers in Virtual Private Cloud OnDemand.

Virtual data centers function as logical containers for resources that you want to create limits around or group together. Virtual Private Cloud OnDemand is designed to allow for flexible and scalable capacity for your public cloud. You scale capacity by deploying additional virtual machines or by increasing resources for existing virtual machines. You do not allocate set resources to your virtual data centers. However, each virtual data center is implemented with capacity limitations. Adding multiple virtual data centers expands your capacity limits exponentially. See Capacity for Virtual Private Cloud OnDemand for information.

Using multiple virtual data centers allows you to organize resources into more manageable chunks, making them easier to find and manage. You can implement monitoring at the virtual data center level with associated alarms; set events to trigger different responses depending on their location within your virtual data center structure.

Creating a virtual data center creates a gateway automatically, through which you can configure security boundaries. Using virtual data centers, you can define where your network and storage boundaries are (and by association, host boundaries as well).

Adding virtual data centers provides the ability to group virtual machines into customer-defined network segments. Virtual Private Cloud OnDemand leverages the organization network scheme from vCloud Director for L2 network segmentation and network extension. The organization networks use VxLANs as network resource pools. You can create multiple organization networks per virtual data center to segment workloads as needed. See Network Virtualization in Virtual Private Cloud OnDemand in the vCloud AirVirtual Private Cloud OnDemand Networking Guide.

You can create virtual data centers to group virtual machines so that they can work together; for example, by setting up virtual machine load balancing using the gateway services within the virtual data center. See Load Balancer in the vCloud AirVirtual Private Cloud OnDemand Networking Guide.

In sum, having multiple virtual data centers allows you to achieve the following goals:

Group your resources into one or more virtual data centers depending upon your requirements; for example, you can create one virtual data center for your entire company or you can create different virtual data centers for different departments, project teams, or geographic sites.

Isolate particular applications or groups of applications; for example, you can isolate your production applications from development and testing.

Monitor resource usage at the virtual data center level and add more resources if necessary.
