ATIS-0200006 16 Appendix A (Informative) A Service Provider Deployment Options This document describes two approaches - “General” and “Static” - for Virtual Desktop Infrastructure Federation. The two approaches map directly to two dep

6、loyment options. When both options are available, a service provider may use them in combination. The result is a “Hybrid” deployment option that would overcome the resource allocation and cost limitations in the “Static” option while providing the control granularity offered in the “General” option

7、. The Hybrid deployment option is described below. The current hypervisor technologies have a lot in common in terms of the supported operating systems and other system functions like failover and load balancing. As such, it may not be always necessary to instantiate a user virtual machine in a virt

8、ual data center, as suggested by the “Static” option. While moving the user virtual machine from a Primary VDP to the Supporting VDP, the following scheme is suggested: 1. If the user is a premium user, use a virtual machine resource in the virtual data center. 2. If the user is not a premium user,

9、try to find a virtual machine resource with the required user characteristics in the supporting VDP. 3. If step 2 fails, use a virtual machine resource in the virtual data center for the user. 4. If step 3 fails, try to find other supporting VDPs which may not be most proximal to the user. With the

10、“Hybrid”option, 1. The capacity and the cost of the dedicated virtual data center can be kept contained; 2. The supporting VDP is less likely to run out of capacity; and 3. Premium users can benefit from the virtual data center solution. A comparison of the deployment options “General”, “Static”, an

The VD service providers can choose an option convenient to them based on these tradeoffs.
