1.2. Taxonomy

Oracle VDI consists of four main elements, or layers, which are described in more detail in System Overview of Oracle Virtual Desktop Infrastructure in the Oracle Virtual Desktop Infrastructure Administrator's Guide.

Figure 1.1. Oracle VDI Architecture

The diagram shows the four elements of the Oracle VDI system and the components of each layer.

Desktop Access

Oracle VDI provides many ways to access virtual desktops so that a user can work on the same virtual desktop from nearly anywhere, such as from:

Because Oracle VDI hosts these desktops in a relatively secure environment, some of the common risks associated with client devices, such as loss of confidential data, are mitigated.

Management

Oracle VDI manages every aspect of virtual desktop life cycles: creation, configuration, assignment to users, and recycling. To control, configure, and monitor its operation, Oracle VDI provides a command-line interface and the Oracle VDI Manager, a web-based management tool. Specifically for comprehensive centralized monitoring of Oracle VDI resources, a plug-in for Oracle Enterprise Manager is also provided.

Virtualization

Oracle VDI can use any of several popular hypervisors to handle virtualization functionality. The Oracle VM VirtualBox hypervisor, which is well integrated into the Oracle VDI architecture, can be used to provision UNIX and Linux desktops as well as Windows desktops. Oracle VDI also supports Microsoft Hyper-V and VMware vCenter, which provision only Windows desktops. In addition, Oracle VDI supports the use of Remote Desktop Services (RDS) hosts for session-based virtualization.

For security enhancement practices and precautions for non-Oracle products, see the manufacturers' product documentation.

Storage

To store instances of virtual machines, templates, snapshots, and other items associated with virtualization, Oracle VDI supports:
